+
+# This data is by no means authoritative; if you think you know better,
+# go ahead and edit the file (and please send any changes to
+# tz@elsie.nci.nih.gov for general use in the future).
+
+# From Paul Eggert <eggert@twinsun.com> (1997-10-05):
+#
+# A good source for time zone historical data outside the U.S. is
+# Thomas G. Shanks, The International Atlas (4th edition),
+# San Diego: ACS Publications, Inc. (1995).
+#
+# Gwillim Law <LAW@encmail.encompass.com> writes that a good source
+# for recent time zone data is the International Air Transport
+# Association's Standard Schedules Information Manual (IATA SSIM),
+# published semiannually.  Law sent in several helpful summaries
+# of the IATA's data after 1990.
+#
+# Except where otherwise noted, Shanks is the source for entries through 1990,
+# and IATA SSIM is the source for entries after 1990.
+#
+# Another source occasionally used is Edward W. Whitman, World Time Differences,
+# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
+# I found in the UCLA library.
+#
+# A reliable and entertaining source about time zones is
+# Derek Howse, Greenwich time and the discovery of the longitude,
+# Oxford University Press (1980).
+#
+# Previous editions of this database used WAT, CAT, SAT, and EAT
+# for +0:00 through +3:00, respectively,
+# but Mark R V Murray <markm@iafrica.com> reports that
+# `SAST' is the official abbreviation for +2:00 in the country of South Africa,
+# `CAT' is commonly used for +2:00 in countries north of South Africa, and
+# `WAT' is probably the best name for +1:00, as the common phrase for
+# the area that includes Nigeria is ``West Africa''.
+# He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
+#
+# To make things confusing, `WAT' seems to have been used for -1:00 long ago;
+# I'd guess that this was because people needed _some_ name for -1:00,
+# and at the time, far west Africa was the only major land area in -1:00.
+# This usage is now obsolete, as the last use of -1:00 on the African
+# mainland seems to have been 1976 in Western Sahara.
+#
+# To summarize, the following abbreviations seem to have some currency:
+#	-1:00	WAT	West Africa Time (no longer used)
+#	 0:00	GMT	Greenwich Mean Time
+#	 2:00	CAT	Central Africa Time
+#	 2:00	SAST	South Africa Standard Time
+# and Murray suggests the following abbreviation:
+#	 1:00	WAT	West Africa Time
+# I realize that this leads to `WAT' being used for both -1:00 and 1:00
+# for times before 1976, but this is the best I can think of
+# until we get more information.
+#
+# I invented the following abbreviations; corrections are welcome!
+#	 2:00	WAST	West Africa Summer Time
+#	 2:30	BEAT	British East Africa Time (no longer used)
+#	 2:45	BEAUT	British East Africa Unified Time (no longer used)
+#	 3:00	CAST	Central Africa Summer Time (no longer used)
+#	 3:00	SAST	South Africa Summer Time (no longer used)
+#	 3:00	EAT	East Africa Time
+#	 4:00	EAST	East Africa Summer Time (no longer used)

+# We use the same time as McMurdo does.

+# One last quirk about South Pole time.
+# All the electric clocks are usually wrong.
+# Something about the generators running at 60.1hertz or something

+# Maybe if we let them run fast all of the time, we'd get to leave here sooner!!

+# People's Republic of China.  Yes, they really have only one time zone.
+
+# From Bob Devine (1988-01-28):
+# No they don't.  See TIME mag, 1986-02-17 p.52.  Even though
+# China is across 4 physical time zones, before Feb 1, 1986 only the
+# Peking (Bejing) time zone was recognized.  Since that date, China
+# has two of 'em -- Peking's and Urumqi (named after the capital of
+# the Xinjiang Uighur Autonomous Region).  I don't know about DST for it.
+#
+# . . .I just deleted the DST table and this editor makes it too
+# painful to suck in another copy..  So, here is what I have for

+# time annually.  Ever since 1993, the change to daylight savings time is
+# on a Thursday night from midnight IST to 1 a.m IDT.  The change back to
+# standard time is on a Saturday night from midnight daylight savings time
+# to 11 p.m. standard time.  1996 is an exception to this rule where the

+
+# Australia
+
+# From John Mackin (1991-03-06):
+# We in Australia have _never_ referred to DST as `daylight' time.
+# It is called `summer' time.  Now by a happy coincidence, `summer'
+# and `standard' happen to start with the same letter; hence, the
+# abbreviation does _not_ change...
+# The legislation does not actually define abbreviations, at least
+# in this State, but the abbreviation is just commonly taken to be the
+# initials of the phrase, and the legislation here uniformly uses
+# the phrase `summer time' and does not use the phrase `daylight
+# time'.
+# Announcers on the Commonwealth radio network, the ABC (for Australian
+# Broadcasting Commission), use the phrases `Eastern Standard Time'
+# or `Eastern Summer Time'.  (Note, though, that as I say in the
+# current australasia file, there is really no such thing.)  Announcers
+# on its overseas service, Radio Australia, use the same phrases
+# prefixed by the word `Australian' when referring to local times;
+# time announcements on that service, naturally enough, are made in UTC.
+
+# From Arthur David Olson (March 8 1992):
+# Given the above, what's chosen for year-round use is:
+#	CST	for any place operating at a GMTOFF of 9:30
+#	WST	for any place operating at a GMTOFF of 8:00
+#	EST	for any place operating at a GMTOFF of 10:00
+
+# From Paul Eggert (1995-12-19):
+# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
+# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
+# reports that NSW's fall 1995 change will occur at 2:00,
+# but Robert Elz says it's been 3:00 in Victoria since 1970
+# and perhaps the newspaper's `2:00' is referring to standard time.
+# For now we'll continue to assume 2:00s for changes since 1960.

+# New Zealand, from Elz' asia 1.1
+# Elz says "no guarantees"
+
+# From Mark Davies (1990-10-03):
+# the 1989/90 year was a trial of an extended "daylight saving" period.
+# This trial was deemed successful and the extended period adopted for
+# subsequent years (with the addition of a further week at the start).
+# source -- phone call to Ministry of Internal Affairs Head Office.

+# From Arthur David Olson (1992-03-08):
+# The chosen rules use the Davies October 8 values for the start of DST in 1989
+# rather than the October 1 value.
+
+# From Paul Eggert (1995-12-19);
+# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
+# Robert Uzgalis <buz@cs.aukuni.ac.nz> writes that the New Zealand Daylight
+# Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard
+# time on both the first Sunday in October and the third Sunday in March.
+# As with Australia, we'll assume the tradition is 2:00s, not 2:00.
+#
+# From Paul Eggert (1996-11-22):
+# Shanks gives no data for Chatham; usno1989 says it's +12:45,
+# usno1995 says it's +12:45/+13:45, and IATA SSIM (1991/1996)
+# gives the NZ rules but with transitions at 2:45 local standard time.
+# Guess that they adopted DST in 1990.

+# Fiji
+
+# Howse writes (p 162) that in 1879 the British governor of Fiji
+# enacted an ordinance standardizing the islands on +12:00.
+# Perhaps it didn't take.  We go with Shanks's more precise date in 1915.

+# Johnston
+
+# Johnston data is from usno1995.
+
+# Kiribati
+
+# From Paul Eggert (1996-01-22):
+# Today's _Wall Street Journal_ (page 1) reports that Kiribati
+# ``declared it the same day throught the country as of Jan. 1, 1995''
+# as part of the competition to be first into the 21st century.
+
+# Kwajalein
+
+# In comp.risks 14.87 (26 August 1993), Peter Neumann writes:
+# I wonder what happened in Kwajalein, where there was NO Friday,
+# 1993-08-20.  Thursday night at midnight Kwajalein switched sides with
+# respect to the International Date Line, to rejoin its fellow islands,

+# N Mariana Is, Guam
+
+# Howse writes (p 162) ``The Spaniards, on the other hand, reached the

+# Ignore this for now, as we have no hard data.  See also Asia/Manila.

+
+# Alan Eugene Davis <adavis@kuentos.guam.net> writes (1996-03-16),

+# Shanks writes that Truk switched from GMT+10 to GMT+11 on 1978-10-01;

+# United Kingdom
+# The UK and its colonies adopted the Gregorian calendar on 1752-09-14.
+
+# From Peter Ilieve <peter@memex.co.uk> (1994-07-06):
+#
+# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
+# historical vistas along the Thames in west London. There was a photo
+# and a sketch map showing some of the sightlines involved. One paragraph
+# of the text said:
+#
+# `An old stone obelisk marking a forgotten terrestrial meridian stands
+# beside the river at Kew. In the 18th century, before time and longitude
+# was standardised by the Royal Observatory in Greenwich, scholars observed
+# this stone and the movement of stars from Kew Observatory nearby. They
+# made their calculations and set the time for the Horse Guards and Parliament,
+# but now the stone is obscured by scrubwood and can only be seen by walking
+# along the towpath within a few yards of it.'
+#
+# I have a one inch to one mile map of London and my estimate of the stone's
+# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should
+# be within about +-2". The Ordnance Survey grid reference is TQ172761.
+#
+# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
+
+# From Paul Eggert <eggert@twinsun.com> (1993-11-18):
+#
+# Howse writes that Britain was the first country to use standard time.
+# The railways cared most about the inconsistencies of local mean time,
+# and it was they who forced a uniform time on the country.
+# The original idea was credited to Dr. William Hyde Wollaston (1766-1828);
+# it was popularized in 1840 by Capt. Basil Hall, RN (1788-1844),
+# famed explorer and former Commissioner for Longitude.
+# The first railway to adopt London time was the Great Western Railway
+# in November 1840; other railways followed suit, and by 1847 most
+# (though not all) railways used London time.  On 1847 Sep 22 the
+# Railway Clearing House, an industry standards body, recommended that GMT be
+# adopted at all stations; the January 1848 Bradshaw's lists most major
+# railways as using GMT.  By 1855 the vast majority of public
+# clocks in Britain were set to GMT (though some, like the Great Clock
+# in Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
+# one for local time and one for GMT).  The last major holdout was the legal
+# system, which stubbornly stuck to local time for many years, leading
+# to oddities like polls opening at 08:13 and closing at 16:13.
+# The legal system finally switched to GMT when the Statutes (Definition
+# of Time) Act took effect; it received the Royal Assent on 1880 Aug 2.
+#
+# In the tables below, we condense this complicated story into a single
+# transition date for London, namely 1847 Sep 22.  We don't know as much
+# about Dublin, so we use 1880 Aug 2, the legal transition time.
+
+# From Paul Eggert (1996-06-12):
+# Summer Time was first seriously proposed by William Willett (1857-1915),
+# a London builder who circulated a pamphlet ``Waste of Daylight'' (1907)
+# that proposed advancing clocks 20 minutes on each of four Sundays in April,
+# and retarding them by the same amount on four Sundays in September.
+# A bill was drafted in 1909 and introduced in Parliament several times,
+# but it met with ridicule and opposition, especially from farming interests.
+# One-hour Summer Time was eventually adopted as a wartime measure in 1916.
+
+# From Paul Eggert (1996-09-03):
+# The OED Supplement says that the English originally said ``Daylight Saving''
+# when they were debating the adoption of DST in 1908; but by 1916 this
+# term appears only in quotes taken from DST's opponents, whereas the
+# proponents (who eventually won the argument) are quoted as using ``Summer''.
+
+# From Arthur David Olson (1989-01-19):
+#
+# A source at the British Information Office in New York avers that it's
+# known as "British" Summer Time in all parts of the United Kingdom.
+
+# Date: 4 Jan 89 08:57:25 GMT (Wed)
+# From: Jonathan Leffler <nih-csl!uunet!mcvax!sphinx.co.uk!john>
+# [British Summer Time] is fixed annually by Act of Parliament.
+# If you can predict what Parliament will do, you should be in
+# politics making a fortune, not computing.
+
+# From Chris Carrier <72157.3334@CompuServe.COM> (1996-06-14):
+# I remember reading in various wartime issues of the London Times the
+# acronym BDST for British Double Summer Time.  Look for the published
+# time of sunrise and sunset in The Times, when BDST was in effect, and
+# if you find a zone reference it will say, "All times B.D.S.T."

+# From Peter Ilieve <peter@aldie.co.uk> (1998-01-12):
+# The following list attempts to show the complete history of Summer Time
+# legislation in the United Kingdom, and has quite a bit to say about
+# the Isle of Man and the Channel Islands as well.
+#
+# Things that I have not personally seen are marked (???). Things that
+# I haven't seen but Joseph Myers has are marked (jsm). The problem
+# with finding old Orders (rather than Acts) is that nobody seems to
+# keep the actual documents themselves, not even the Government. They
+# get bound into annual volumes, which are published, but by the time
+# this happens the Orders are mainly spent as the years they refer
+# to have come and gone, so they don't get included in the annual
+# volumes.
+#
+# Thanks are due to my learned legal friend Lorna Montgomerie, who dug out
+# the dusty old statutes, to Melanie Allison of the Ministry of Defence,
+# who provided the wartime regulations and a snippet of Hansard explaining
+# why double summer time started on a Monday in 1945 (it was Easter),
+# and to Joseph Myers <jsm28@cam.ac.uk>, who tracked down the Orders
+# up to 1945, some of the old Acts, and the first five EC Directives.
+#
+# Some definitions:
+#
+# Great Britain: England, Scotland and Wales
+# United Kingdom: Great Britain plus Ireland (up to 1922) or Northern
+# Ireland (since 1922)
+# S.I.: Statutory Instrument, the modern name for secondary legislation
+# S.R.&O.: Statutory Rules and Orders, the older name for secondary legislation
+#
+# Unless otherwise specified, Acts and secondary legislation are assumed
+# to apply throughout the United Kingdom, but not to the Isle of Man
+# or the Channel Islands.
+#
+# Some of the Acts and Orders I found in various libraries, and I don't
+# have copies. When I looked at them I was looking for dates and not things
+# like whether they applied to the Bailiwick of Jersey. I will try to
+# check these documents again.
+#
+# ---
+#
+# - The Statutes (Definition of Time) Act, 1880 (43 & 44 Vict. c. 9)
+#
+# Defined Greenwich mean time to be the standard time in Great Britain
+# and Dublin mean time to be the standard time in Ireland, superseding
+# various forms of local mean time.
+#
+# - The Statutory Time Act, 1883 (???)
+#
+# An Act of Tynwald, the Isle of Man Parliament. It appears to have
+# defined the standard time on the Isle of Man as GMT but as I haven't
+# seen it I don't know if it used Greenwich mean time, some other definition,
+# or just said that Isle of Man time would be the same as in Great Britain.
+#
+# - The Isle of Man (War Legislation) Act, 1914 (4 & 5 Geo. 5. c. 62) (???)
+#
+# Gives the power, by Order in Council, to extend wartime legislation
+# to the Isle of Man.
+#
+# - The Summer Time Act, 1916 (6 & 7 Geo. 5. c. 14)
+#
+# Introduced Summer Time for the first time, in Great Britain and Ireland.
+# Specified a one hour offset from GMT (DMT in Ireland), dates of
+# Sunday 21 May and Sunday 1 October and times of 02:00 (GMT/DMT).
+# Gave a power to make Orders in subsequent years, for the duration
+# of the then current war.
+#
+# - The Time (Ireland) Act, 1916 (6 & 7 Geo. 5. c. 45)
+#
+# This abolished Dublin mean time at 02:00 DMT on Sunday 1 October 1916,
+# bringing the whole of the United Kingdom onto GMT. As Ireland was behind
+# GMT/BST at 02:00 DMT on 1 Oct Great Britain had already put the clocks back.
+# Using Paul Eggert's suggestion of IST for Irish Summer Time and the figure
+# derived from Whitman for the offset of IST from GMT (00:34:39) the sequence
+# would have been:
+# Dublin        London
+# 02:34:38 IST  02:59:59 BST
+# 02:34:39 IST  02:00:00 GMT
+# 02:59:59 IST  02:25:20 GMT
+# 02:25:21 GMT  02:25:21 GMT
+# with the transition 03:00:00 IST -> 02:00:00 DMT -> 02:25:21 GMT all at once.
+#
+# - S.R.&O. 1916, No. 382
+#
+# An Order made under the Isle of Man (War Legislation) Act, 1914
+# extending the Summer Time Act, 1916 to the Isle of Man. Dated
+# 23 May 1916, two days after the start of Summer Time, but it says that
+# the Act is deemed to have taken effect in the Isle of Man at the same
+# time as it took effect in the United Kingdom.
+#
+# - S.R.&O. 1917, No. 362
+#
+# An Order made under the Summer Time Act, 1916 giving dates
+# for Summer Time in 1917 of Sunday 8 April to Monday 17 September,
+# both at 02:00 GMT. Note that Summer Time ends on a Monday.
+#
+# - S.R.&O. 1917, No. 358
+#
+# An Order made under the Summer Time (Isle of Man) Act, 1916
+# (the thing created by S.R.&O. 1916, No. 382) specifying the same
+# dates of 8 April to 17 September, at 02:00 GMT for the Isle of Man.
+#
+# - S.R.&O. 1918, No. 274
+#
+# An Order made under the Summer Time Act, 1916 giving dates
+# for Summer Time in 1918 of Sunday 24 March to Monday 30 September,
+# both at 02:00 GMT.
+#
+# - S.R.&O. 1918, No. 429
+#
+# The matching Isle of Man Order for 1918 with the same dates and times.
+#
+# - S.R.&O. 1919, No. 297
+#
+# An Order made under the Summer Time Act, 1916 giving dates
+# for Summer Time in 1919 of Sunday 30 March to Monday 29 September,
+# both at 02:00 GMT.
+#
+# - S.R.&O. 1919, No. 366
+#
+# The matching Isle of Man Order for 1919 with the same dates and times.
+#
+# - S.R.&O. 1920, No. 458
+#
+# An Order made under the Summer Time Act, 1916 giving dates
+# for Summer Time in 1920 of Sunday 28 March to Monday 27 September,
+# both at 02:00 GMT.
+#
+# - S.R.&O. 1920, No. 573
+#
+# The matching Isle of Man Order for 1920 with the same dates and times.
+#
+# - S.R.&O. 1920, No. 1844
+#
+# An Order modifying both S.R.&O. 1920, No. 458 and S.R.&O. 1920, No. 573 to
+# change the end date for Summer Time from Monday 27 September to
+# Monday 25 October (the time remaining 02:00 GMT). The 1989 Green
+# Paper (Cm 722) says this was done because of a coal strike.
+#
+# - The War Emergency Laws (Continuance) Act, 1920 (10 & 11 Geo. 5. c. 5) (???)
+#
+# This extends the power to make Orders under the Summer Time Act, 1916
+# for a period of 12 months after the termination of the war.
+# I haven't seen this one so I don't know when it came into force, or
+# when the law deemed the termination of the war to have been.
+#
+# - S.R.&O. 1921, No. 363
+#
+# An Order made under the Summer Time Act, 1916 and the War
+# Emergency Laws (Continuance) Act, 1920 giving dates for Summer Time
+# in 1921 of Sunday 3 April to Monday 3 October, both at 02:00 GMT.
+#
+# - S.R.&O. 1921, No. 364
+#
+# The matching Isle of Man Order for 1921 with the same dates and times.
+#
+# - S.R.&O. 1922, No. 264 (???)
+#
+# This probably defines Summer Time for 1922 as the Summer Time Act, 1922
+# was passed after the start date. Dates from Cm 722:
+#   1922: 26 March to 8 October
+#
+# - S.R.&O. 1922, No. 290 (???)
+#
+# This is probably the matching Isle of Man Order.
+#
+# - The Summer Time Act, 1922 (12 & 13 Geo. 5. c. 22)
+#
+# This specifies an offset of 1 hour and dates of the day after the third
+# Saturday in April, unless that be Easter, in which case it is the day after
+# the second Saturday, and the day after the third Saturday in September.
+# The time is 02:00 GMT. It applied in 1922 and 1923, and longer if Parliament
+# so approved. It applied to the Isle of Man and the Channel Islands as well.
+# Came into Force on 20 July 1920. Note the reversion to ending on a Sunday.
+#
+# - S.R.&O. 1922, No. 1205
+#
+# An Order made under the War Emergency Laws (Continuance) Act, 1920
+# dated 13 October 1922. It revokes (among other things) the Order extending
+# the Summer Time Act, 1916 to the Isle of Man.
+#
+# - The Expiring Laws Continuance Act, 1923 (13 & 14 Geo. 5. c. 37) (jsm)
+#
+# This extended the Summer Time Act, 1922 (among other things) until
+# 31 December 1924.
+#
+# - The Expiring Laws Continuance Act, 1924 (15 Geo. 5. c. 1) (jsm)
+#
+# This further extended the Summer Time Act, 1922 (among other things) until
+# 31 December 1925.
+#
+# - The Time Act (Northern Ireland), 1924 (14 & 15 Geo. 5. c. 24 (N.I.))
+#
+# This Act says that while it remains in force, any Act or Order relating
+# to the time for general purposes in Great Britain shall also apply
+# in Northern Ireland, and the Time (Ireland) Act, 1916 shall have effect
+# accordingly.
+#
+# - The Summer Time Act, 1925 (15 & 16 Geo. 5. c. 64)
+#
+# This makes the 1922 Act permanent, with a change to the end date to the
+# day after the first Saturday in October. Came into force on 7 August 1925.
+#
+# - The Emergency Powers (Defence) Act, 1939 (2 & 3 Geo. 6. c. 62) (???)
+#
+# I haven't seen this one. It presumably gave the Government powers to
+# do all manner of things during the newly started war.
+#
+# - The Defence (Summer Time) Regulations, 1939, S.R.&O. 1939, No. 1379
+#
+# These were made under the Emergency Powers (Defence) Act, 1939.
+# They change the end date to be the day after the third Saturday in November.
+#
+# - S.R.&O. 1940, No. 1883
+#
+# An Order in Council amending the Defence (Summer Time) Regulations, 1939.
+# This continues summer time throughout the year after it starts in 1940.
+# There was another Order (S.R.&O. 1940, No. 172) that I assume had merely
+# changed the dates, to start on 4 February, and was then superseded by this
+# one. I haven't seen No. 172 so I don't know what end date it would have
+# specified. The dates from Cm 722:
+#   1940: Summer Time starts on 4 February
+#
+# - S.R.&O. 1941, No. 476
+#
+# Another Order amending the Defence (Summer Time) Regulations, 1939.
+# This introduces double summer time, starting at 01:00 GMT on the day after
+# the first Saturday in May and ending at 01:00 GMT on the day after the
+# second Saturday in August, offset another hour from normal summer time,
+# which continues throughout the rest of the year.
+#
+# - S.R.&O. 1942, No. 506
+#
+# Another Order amending the Defence (Summer Time) Regulations, 1939.
+# This changes the start date of Double Summer Time to the day after the first
+# Saturday in April, bringing it forward from May.
+#
+# - S.R.&O. 1944, No. 932
+#
+# This changed the end date of Double Summer Time to 17 September 1944.
+# (I don't have the text of this, just a note of what it did, the text almost
+# certainly had the `day after the nth Saturday' form.)
+#
+# - S.R.&O. 1945, No. 312 (???)
+#
+# Probably defines the dates of Double Summer Time in 1945.
+# I do have this quote from Hansard (the official record of the United Kingdom
+# Parliament), Oral Answers, 1 March 1945, cols 1559--60:
+#
+#  `58. Major Sir Goronwy Owen asked the Secretary of State for the Home
+#   Department if he is now able to state the Government's proposals
+#   regarding double summer time.
+#
+#   [two other similar questions omitted]
+#
+#   Mr. H. Morrison: The Government, in reviewing the matter, have
+#   considered, [...] the conclusion has been reached that the adoption of
+#   double summer time from the beginning of April is essential to the
+#   maintenance of the war effort. [...] As 1st April is Easter Sunday,
+#   when very early services are held in many churches, it is proposed that
+#   double summer time shall start not in the night preceding Easter
+#   Sunday, but in the night of Sunday-Monday so that it will operate from
+#   Monday, 2nd April.'
+#
+# Cm 722 gives dates of:
+#   1945: Double Summer time: 2 April to 15 July
+#   1945: Summer Time ends on 7 October
+#
+# - S.R.&O. 1945, No. 1208
+#
+# An Order under the Emergency Powers (Defence) Acts, 1939 and 1940 revoking
+# a long list of things, including the Defence (Summer Time) Regulations, 1939.
+# This meant that Summer Time reverted to being set by the 1922 and 1925 Acts.
+#
+# - The Summer Time Act, 1947 (10 & 11 Geo. 6. c. 16)
+#
+# Came into force on 11 March 1947. Amended the Summer Time Acts, 1922 and
+# 1925 to change the dates of Summer Time and to introduce Double Summer Time
+# (although it doesn't give this, or any, name for this period of 2 hour
+# offset from GMT). Dates are given for 1947 only and are: 02:00 GMT Sunday
+# 16 March, 01:00 GMT Sunday 13 April, 01:00 GMT Sunday 10 August, and 02:00
+# Sunday 2 November. It gave a power to make Orders for subsequent years,
+# both to vary the dates and to continue Double Summer Time. It applied
+# to the Isle of Man and the Channel Islands.
+#
+# - Summer Time Order, 1948 (S.I. 1948/495) (???)
+# - Summer Time Order, 1949 (S.I. 1949/373) (???)
+# - Summer Time Order, 1950 (S.I. 1950/518) (???)
+# - Summer Time Order, 1951 (S.I. 1951/430) (???)
+# - Summer Time Order, 1952 (S.I. 1952/451) (???)
+#
+# These presumably give the dates of Summer Time for the relevent years.
+# There was no Double Summer Time. The dates given in the 1989 Green Paper
+# for these years are:
+#   1948: 14 March to 31 October
+#   1949: 3 April to 30 October
+#   1950: 16 April to 22 October
+#   1951: 15 April to 21 October
+#   1952: 20 April to 26 October
+# After 1952 things revert back to the 1922 and 1925 Acts.
+#
+# - The Interpretation Act (Northern Ireland), 1954 (1954 c. 33 (N.I.)) (???)
+#
+# I presume that section 39 of this Act is similar to section 9 of the
+# Interpretation Act, 1978 (listed below) in specifying GMT as the
+# legal time in Northern Ireland, replacing the Time (Ireland) Act, 1916.
+#
+# - Summer Time Order, 1961 (S.I. 1961/71)
+#
+# Specified dates of 26 March and 29 October (02:00 GMT) for 1961
+#
+# - Summer Time (1962) Order, 1961 (S.I. 1961/2465)
+#
+# Specified dates of 25 March to 28 October (02:00 GMT) for 1962.
+#
+# - Summer Time Order, 1963 (S.I. 1963/81)
+#
+# Specified dates of 31 March to 27 October (02:00 GMT) for 1963.
+#
+# - Summer Time (1964) Order, 1963 (S.I. 1963/2101)
+#
+# Specified dates of 22 March to 25 October (02:00 GMT) for 1964.
+#
+# - Summer Time Order, 1964 (S.I. 1964/1201)
+#
+# Specified dates for three years (all 02:00 GMT):
+#   1965: 21 March to 24 October
+#   1966: 20 March to 23 October
+#   1967: 19 March to 29 October
+#
+# - Summer Time Order, 1967 (S.I. 1967/1148)
+# - Summer Time Order, 1968 (S.I. 1968/117)
+#
+# The first of these specifies dates for 1968 of 18 February for the United
+# Kingdom but 7 April for the Isle of Man, both ending on 27 October,
+# all at 02:00 GMT. The second Order changes the Isle of Man start date
+# to 18 February to match the United Kingdom.
+#
+# - The British Standard Time Act 1968 (1968 c. 45)
+#
+# This came into force on 27 October 1968 and continued summer time throughout
+# the year. It expired at 02:00 GMT on 31 October 1971, as specified in the
+# Act, as Parliament did not move to make this experment permanent.
+# It applied to the Isle of Man and the Channel Islands.
+#
+# Interestingly, it says baldly `This Act shall come into force on
+# 27 October 1968', without giving a time. As S1 of the Act merely
+# stated that `The time for general purposes in the United Kingdom
+# (to be known as British standard time) shall be one hour in
+# advance of Greenwich mean time throughout the year; ...' you could
+# possibly argue that the start time of BStandardT was 00:00 1968-10-27,
+# especially as the Act repealed the Summer Time Acts 1916--1947 in toto,
+# thereby destroying the authority of the Summer Time Order specifying
+# summer time in 1968.
+#
+# - The Manx Time Act 1968
+#
+# This is an Act of Tynwald (the Isle of Man Parliament) that said that
+# henceforth Manx time would be the same as the time in Great Britain.
+#
+# - The Summer Time Act 1972 (1972 c. 6)
+#
+# This specified a reversion to normal Summer Time behaviour with a start
+# date of the day after the third Saturday in March, unless that is Easter,
+# when it is the day after the second Saturday, and an end date of the day
+# after the fourth Saturday in October. Times are at 02:00 GMT, offset is
+# 1 hour. It gives the power to make Orders to vary these dates and
+# times. This Act is still in force and is the legal authority for
+# implementing the EC Directives in the United Kingdom.
+#
+# - The Interpretation Act 1978 (1978 c. 30)
+#
+# Section 9 of this Act replaces section 1 of the Statutes (Definition of
+# Time) Act, 1880 with very similar wording maintaining GMT as the legal
+# time in Great Britain. This does not apply in Northern Ireland (it
+# has its own Interpretation Act listed above).
+#
+# - Council Directive of 22 July 1980 on summertime arrangements (80/737/EEC)
+#
+# The first of the European Directives on Summer Time. It specified start
+# dates for 1981 and 1982. No agreement had been reached on end dates.
+# Only dates were given, there was no rule like `last Sunday in March'.
+# The main change for the United Kingdom was a move to a 01:00 GMT change
+# time. The dates:
+#   1981: 29 March
+#   1982: 28 March
+#
+# - Summer Time Order, 1980 (S.I. 1980/1089)
+#
+# Specified dates for 1981 and 1982, with the start dates as in the
+# EC Directive and all times 01:00 GMT:
+#   1981: 29 March to 25 October
+#   1982: 28 March to 24 October
+#
+# - Second Council Directive of 10 June 1982 on summertime arrangements
+#   (82/399/EEC)
+#
+# The next European Directive. Specified dates for three years, 1983 to 1985.
+# Agreement still hadn't been reached on a common end date, and wouldn't
+# be until 1994 with the appeareance of the seventh Directive with a common
+# date for 1996 and beyond, but this time the Directive gave two sets of
+# end dates. The start date was specified by rule: the last Sunday in March.
+# All times were 01:00 GMT. The end dates were given without rule, as:
+#   1983: 25 September or 23 October
+#   1984: 30 September or 28 october
+#   1985: 29 September or 27 October
+#
+# - Summer Time Order, 1982 (S.I. 1982/1673)
+#
+# Implemented the second EC Directive, using the October end dates.
+#   1983: 27 March to 23 October
+#   1984: 25 March to 28 october
+#   1985: 31 March to 27 October
+#
+# - Third Council Directive of 12 December 1984 on summertime arrangements
+#   (84/634/EEC)
+#
+# Specified start dates of the last Sunday in March and two sets of end
+# dates, last Sunday in September and fourth Sunday in October, all at
+# 01:00 GMT. The end dates were also specified as dates:
+#   1986: 28 September or 26 October
+#   1987: 27 September or 25 October
+#   1988: 25 September or 23 October
+#
+# - Summer Time Order, 1986 (S.I. 1986/223)
+#
+# Implemented the third EC Directive, using the October end dates.
+#   1986: 30 March to 26 October
+#   1987: 29 March to 25 October
+#   1988: 27 March to 23 October
+#
+# - Council Directive of 20 December 1985 amending Directive 84/634/EEC
+#   on summertime arrangements (85/582/EEC)
+#
+# This was to do with the accession of Spain and Portugal to the EEC.
+# The previous directve had used wording like `Member States belonging
+# to the zero (Greenwich) time zone' when refering to the different
+# sets of end dates. Portugal was in that time zone but was not going
+# to follow the United Kingdom and Ireland dates, so the text was reworded
+# without any change to the dates themselves.
+#
+# - Fourth Council Directive of 22 December 1987 on summertime arrangements
+#   (88/14/EEC)
+#
+# This Directive covered only a single year: 1989. My guess is that
+# this was because 1989 was one of the years when the historic United Kingdom
+# end date of the Sunday after the fourth Saturday in October differed from
+# the rule in the previous Directive of the fourth Sunday in October.
+# All times are 01:00 GMT. No rule was specified, specific dates were given:
+#   1989: 26 March to 24 September or 29 October
+#
+# - Summer Time Order, 1988 (S.I. 1988/931)
+#
+# Implemented the dates of 26 March to 29 October for 1989.
+#
+# - Fifth Council Directive of 21 December 1988 on summertime arrangements
+#   (89/47/EEC)
+#
+# Covered the three years 1990 to 1992. All times are 01:00 GMT. Gave both
+# rules (last Sunday in March, last Sunday in September or fourth Sunday
+# in October) and specific dates:
+#   1990: 25 March to 30 September or 28 October
+#   1991: 31 March to 29 September or 27 October
+#   1992: 29 March to 27 September or 25 October
+#
+# - Summer Time Order, 1989 (S.I. 1989/985)
+#
+# Implemented the fifth Directive using the October end dates.
+#
+# - Sixth Council Directive 92/20/EEC of 26 March 1992 on summertime
+#   arrangements
+#
+# Covered the two years 1993 and 1994. All times are 01:00 GMT. Specified
+# both rules (same as the fifth Directive) and specific dates:
+#   1993: 28 March to 26 September or 24 October
+#   1994: 27 March to 25 September or 23 October
+#
+# - Summer Time Order, 1992 (S.I. 1992/1729)
+#
+# Implemented the sixth Directive using the October end dates.

+# - Seventh Directive 94/21/EC of the European Parliament and of the Council
+#   of 30 May 1994 on summer-time arrangements
+#
+# Covered the three years 1995 to 1997. Agreement had finally been reached
+# on a common end date, to start in 1996. Both rules and dates were given.
+# The rules were the same last Sunday in March to last Sunday in September
+# or fourth Sunday in October for 1995, with the end rule changing to the
+# last Sunday in October for 1996 and 1997. The year 1995 was another of
+# the tricky ones where the EC and traditional United Kingdom rules differed
+# but this time the UK changed on the fourth Sunday, 22 October, earlier
+# than usual. All times are 01:00 GMT. Specific dates were also given:
+#   1995: 26 March to 24 September or 22 October
+#   1996: 31 March to 27 October
+#   1997: 30 March to 26 October
+#
+# - Summer Time Order 1994 (S.I. 1994/2798)
+#
+# Implements the seventh Directive using the October end date in 1995.
+# Applies also to the Bailiwick of Guernsey but not to the Bailiwick of
+# Jersey or the Isle of Man, which have their own (unspecified) legislation
+# on the subject.
+#
+# - Eighth Directive 97/44/EC of the European Parliament and of the Council
+#   of 22 July 1997 on summer-time arrangements
+#
+# Covers four years: 1998 to 2001. All times are 01:00 GMT. Specifies both
+# rules, last Sunday in March and last Sunday in October, and specific dates:
+#   1998: 29 March to 25 October
+#   1999: 28 March to 31 October
+#   2000: 26 March to 29 October
+#   2001: 25 March to 28 October
+#
+# - Summer Time Order 1997 (S.I. 1997/2982)
+#
+# Implements the eighth Directive. Has the same text about the Isle of Man,
+# Guernsey and Jersey as the 1994 Order.
+
+# From Joseph S. Myers <jsm28@hermes.cam.ac.uk> (1998-01-06):
+#
+# The legal time in the UK outside of summer time is definitely GMT, not UTC;
+# see Lord Tanlaw's speech
+# <a href="http://www.parliament.the-stationery-office.co.uk/pa/ld199697/ldhansrd/pdvn/lds97/text/70611-20.htm#70611-20_head0">
+# (Lords Hansard 11 June 1997 columns 964 to 976)
+# </a>.
+
+# From Paul Eggert <eggert@twinsun.com> (1996-06-12):
+#
+# The date `20 April 1924' in the table of ``Summer Time: A
+# Consultation Document'' (Cm 722, 1989) table is a transcription error;
+# 20 April was an Easter Sunday.  Shanks has 13 April, the correct date.
+# Also, the table is not quite right for 1925 through 1938; the correct rules
+# (which Shanks uses) are given in the Summer Time Acts of 1922 and 1925.
+# Shanks and the UK Government paper disagree about the Apr 1956 transition;
+# since we have no other data, and since Shanks was correct in the other
+# points of disagreement about London, we'll believe Shanks for now.
+# Also, for lack of other data, we'll follow Shanks for Eire in 1940-1948.
+#
+# Given Peter Ilieve's comments, the following claims by Shanks are incorrect:
+#     * Wales did not switch from GMT to daylight saving time until
+#	1921 Apr 3, when they began to conform with the rest of Great Britain.
+# Actually, Wales was identical after 1880.
+#     * Eire had two transitions on 1916 Oct 1.
+# It actually just had one transition.
+#     * Northern Ireland used single daylight saving time throughout WW II.
+# Actually, it conformed to Britain.
+#     * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
+# Actually, that date saw the usual switch to summer time.
+# Standard time was not changed until 1968-10-27 (the clocks didn't change).
+#
+# The following claims by Shanks are possible though doubtful;
+# we'll ignore them for now.
+#     * Jersey, Guernsey, and the Isle of Man did not switch from GMT
+#	to daylight saving time until 1921 Apr 3, when they began to
+#	conform with Great Britain.
+#     * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
+#
+#
+# Whitman says Dublin Mean Time was -0:25:21, which is more precise than Shanks.
+
+# From an anonymous contributor (1996-06-02):
+# The law governing time in Ireland is under Statutory Instrument SI 395/94,
+# which gives force to European Union 7th Council Directive # 94/21/EC.
+# Under this directive, the Minister for Justice in Ireland makes appropriate
+# regulations. I spoke this morning with the Secretary of the Department of
+# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
+# "Irish Summer Time", abbreviated to "IST".

+# Iceland
+#
+# From Adam David <adam@veda.is> (1993-11-06):
+# The name of the timezone in Iceland for system / mail / news purposes is GMT.
+#
+# (1993-12-05):
+# This material is paraphrased from the 1988 edition of the University of
+# Iceland Almanak.
+#
+# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
+# behind GMT. Previously, local mean solar time was used in different parts
+# of Iceland, the almanak had been based on Reykjavik mean solar time which
+# was 1 hour and 28 minutes behind GMT.
+#
+# "first day of winter" referred to [below] means the first day of the 26 weeks
+# of winter, according to the old icelandic calendar that dates back to the
+# time the norsemen first settled Iceland.  The first day of winter is always
+# Saturday, but is not dependent on the Julian or Gregorian calendars.
+#
+# (1993-12-10):
+# I have a reference from the Oxford Icelandic-English dictionary for the
+# beginning of winter, which ties it to the ecclesiastical calendar (and thus
+# to the julian/gregorian calendar) over the period in question.
+#	the winter begins on the Saturday next before St. Luke's day
+#	(old style), or on St. Luke's day, if a Saturday.
+# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
+# might be a reference to the Julian calendar as opposed to Gregorian, or it
+# might mean something else (???).
+#
+# From Paul Eggert <eggert@twinsun.com> (1993-12-09):
+# The Iceland Almanak, Shanks and Whitman disagree on many points.
+# We go with the Almanak, except for one claim from Shanks, namely that
+# Reykavik was -1:28 from 1837 to 1908, local mean time before that.

+# and (unless otherwise specified) guessed what happened after 1991.
+# Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,

+# `MSK' and `MSD' were born and used initially on Moscow computers with
+# Unix-like OSes by several developer groups (e.g. Demos group, Kiae group)....
+# The next step was the UUCP network, the Relcom predecessor
+# (used mainly for mail), and MSK/MSD was actively used there.

+# </a>:
+#
+# In 1700, Denmark made the transition from Julian to Gregorian.  Sweden
+# decided to *start* a transition in 1700 as well, but rather than have one of
+# those unsightly calendar gaps :-), they simply decreed that the next leap
+# year after 1696 would be in 1744 -- putting the whole country on a calendar
+# different from both Julian and Gregorian for a period of 40 years.
+#
+# However, in 1704 something went wrong and the plan was not carried through;
+# they did, after all, have a leap year that year.  And one in 1708.  In 1712
+# they gave it up and went back to Julian, putting 30 days in February that
+# year!...
+#
+# Then in 1753, Sweden made the transition to Gregorian in the usual manner,
+# getting there only 13 years behind the original schedule.
+#
+# (A previous posting of this story was challenged, and Swedish readers
+# produced the following references to support it: "Tiderakning och historia"
+# by Natanael Beckman (1924) and "Tid, en bok om tiderakning och
+# kalendervasen" by Lars-Olof Lode'n (no date was given).)

+# ...the European time rules are...standardized since 1981, when
+# most European coun[tr]ies started DST.  Before that year, only
+# a few countries (UK, France, Italy) had DST, each according

+# 'Apr firstSun', and not on 'Mar lastSun' as in the following
+# years...
+# But also since 1981 there are some more national exceptions
+# than listed in 'europe': Switzerland, for example, joined DST
+# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep
+# lastSun' in 1981---I don't know how they handle now.

+# The information from Tom Hofmann is (as far as I know) not entirely correct.
+# After a request from chongo at amdahl I tried to retrieve all information
+# about DST in Europe.  I was able to find all from about 1969.
+#
+# ...standardization on DST in Europe started in about 1977 with switches on
+# first Sunday in April and last Sunday in September...
+# In 1981 UK joined Europe insofar that
+# the starting day for both shifted to last Sunday in March.  And from 1982
+# the whole of Europe used DST, with switch dates April 1 and October 1 in
+# the Sov[i]et Union.  In 1985 the SU reverted to standard Europe[a]n switch
+# dates...
+#
+# It should also be remembered that time-zones are not constants; e.g.
+# Portugal switched in 1976 from MET (or CET) to WET with DST...
+# Note also that though there were rules for switch dates not
+# all countries abided to these dates, and many individual deviations
+# occurred, though not since 1982 I believe.  Another note: it is always
+# assumed that DST is 1 hour ahead of normal time, this need not be the
+# case; at least in the Netherlands there have been times when DST was 2 hours
+# in advance of normal time.

+#	Atlantic standard time
+#	eastern standard time
+#	central standard time
+#	mountain standard time

+# Saskatchewan
+
+# From Paul Eggert (1996-06-12):
+# Shanks writes that since 1970 most of this region has been like Regina.
+# Some western towns (e.g. Swift Current) switched from MST/MDT to CST in 1972.
+# Other western towns (e.g. Lloydminster) are like Edmonton.
+
+# From W. Jones <jones@skdad.usask.ca> (1992-11-06):
+# The. . .below is based on information I got from our law library, the
+# provincial archives, and the provincial Community Services department.
+# A precise history would require digging through newspaper archives, and
+# since you didn't say what you wanted, I didn't bother.
+#
+# Saskatchewan is split by a time zone meridian (105W) and over the years
+# the boundary became pretty ragged as communities near it reevaluated
+# their affiliations in one direction or the other.  In 1965 a provincial
+# referendum favoured legislating common time practices.
+#
+# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
+# Saskatchewan 1978) was proclaimed, and established that the eastern
+# part of Saskatchewan would use CST year round, that districts in
+# northwest Saskatchewan would by default follow CST but could opt to
+# follow Mountain Time rules (thus 1 hour difference in the winter and
+# zero in the summer), and that districts in southwest Saskatchewan would
+# by default follow MT but could opt to follow CST.
+#
+# It took a few years for the dust to settle (I know one story of a town
+# on one time zone having its school in another, such that a mom had to
+# serve her family lunch in two shifts), but presently it seems that only
+# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
+# rules any more; all other districts appear to have used CST year round
+# since sometime in the 1960s.

+# Mexico
+
+# From Guy Harris:
+# Rules are from the Official Airline Guide, Worldwide Edition, for 1987.
+# Rules [before] 1987 are unknown.
+# The comments in the OAG say "Only Ensenada, Mexicale, San Felipe and Tijuana
+# observe DST."  This is presumably Baja California Norte, above 28th parallel,
+# as listed there; [there is also] "Baja California Sur and N. Pacific
+# Coast (States of Sinaloa and Sonora)."
+
+# From Bob Devine (1988-01-28):
+# The Federal District (where Mexico City is) has observed [DST] several
+# times but not recently.
+#
+# I don't where to drawn the line in the North Baja area.  28th latitude
+# sounds good -- but it may be higher (how far [d]o radio stations from
+# San Diego affect culture?).
+#
+# The dates of DST probably go back to 1981.  The rules are the same as
+# US's.  This is going to be a headache for US presidential electi[o]n years!
+
+# From Arthur David Olson (1988-02-13)
+# Since the 1981 starting date is only "probable," we'll keep the 1987
+# starting date below.
+
+# From U. S. Naval Observatory (1989-01-19):
+# MEXICO BAJA CAL N   7 H  BEHIND UTC    BAJA CALIFORNIA SUR AND

+
+# From Arthur David Olson (1989-01-21):
+# April 3 fell on a Sunday in 1988; October 29 fell on a Sunday in 1989.  Ahem.
+# USNO claims there should be four Mexican zones rather than three:
+# a zone that's GMT-8 with DST; a zone that's always GMT-7;
+# a zone that's GMT-6 with DST; and a zone that's always GMT-6.
+
+# From Paul Eggert <eggert@twinsun.com> (1993-11-18):
+# Shanks also says there are four zones, but disagrees about the fourth.
+# Instead of GMT-6 with DST, he says there's GMT-8 without DST.
+
+# From Alan Perry <alan.perry@eng.sun.com> (1996-02-15):
+# A guy from our Mexico subsidiary finally found the Presidential Decree
+# outlining the timezone changes in Mexico.
+# 
+# ------------- Begin Forwarded Message -------------
+# 
+# I finally got my hands on the Official Presidential Decree that sets up the
+# rules for the DST changes. The rules are:
+# 
+# 1. The country is divided in 3 timezones:
+#    - Baja California Norte (the Mexico/BajaNorte TZ)
+#    - Baja California Sur, Nayarit, Sinaloa and Sonora (the Mexico/BajaSur TZ)
+#    - The rest of the country (the Mexico/General TZ)
+#    
+# 2. From the first Sunday in April at 2:00 AM to the last Sunday in October
+#    at 2:00 AM, the times in each zone are as follows:
+#    BajaNorte: GMT+7
+#    BajaSur:   GMT+6
+#    General:   GMT+5
+#    
+# 3. The rest of the year, the times are as follows:
+#    BajaNorte: GMT+8
+#    BajaSur:   GMT+7
+#    General:   GMT+6
+#    
+# The Decree was published in Mexico's Official Newspaper on January 4th.
+# 
+# -------------- End Forwarded Message --------------

+# Times were computed using formulas in the U.S. Naval Observatory's
+# Almanac for Computers 1988; the formulas "will give EqT to an accuracy of
+# [plus or minus two] seconds during the current year."
+#
+# Rounding to the nearest five seconds results in fewer than
+# 256 different "time types"--a limit that's faced because time types are

+# Apparent noon times below are for Riyadh; they're a bit off for other places.
+# Times were computed using a formula provided by the U. S. Naval Observatory:
+#	eqt = -105.8 * sin(l) + 596.2 * sin(2 * l) + 4.4 * sin(3 * l)
+#		-12.7 * sin(4 * l) - 429.0 * cos(l) - 2.1 * cos (2 * l)
+#		+ 19.3 * cos(3 * l);
+# where l is the "mean longitude of the Sun" given by
+#	l = 279.642 degrees + 0.985647 * d
+# and d is the interval in days from January 0, 0 hours Universal Time
+# (equaling the day of the year plus the fraction of a day from zero hours).
+# The accuracy of the formula is plus or minus three seconds.
+#
+# Rounding to the nearest five seconds results in fewer than
+# 256 different "time types"--a limit that's faced because time types are
+# stored on disk as unsigned chars.

+# From Guy Harris:
+# The OAG lists 1987-10-25 and 1988-02-12 as the starting and
+# ending dates, giving them as "estimated date(s) based on previous year".  We
+# infer a rule here from one example, always a dangerous practice....  Yes,
+# they really do switch on Saturday, according to the OAG.
+# "[America/Porto_Acre]" is for the [State] of Acre;
+# "[America/Noronha]" is for Fernando De Noronha.
+
+# From Paul Eggert <eggert@twinsun.com> (1993-11-18):
+# The mayor of Rio recently attempted to change the time zone rules
+# just in his city, in order to leave more summer time for the tourist trade.
+# The rule change lasted only part of the day;
+# the federal government refused to follow the city's rules, and business
+# was in a chaos, so the mayor backed down that afternoon.
+
+# From IATA SSIM (1996-02):
+# _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS),
+# Santa Catarina (SC), Parana (PR), Sao Paulo (SP), Rio de Janeiro (RJ),
+# Espirito Santo (ES), Minas Gerais (MG), Bahia (BA), Goias (GO),
+# Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL].
+# [The last three states are new to this issue of the IATA SSIM.]
+
+# From Gwillim Law (1996-10-07):
+# Geography, history (Tocantins was part of Goias until 1989), and other
+# sources of time zone information lead me to believe that AL, SE, and TO were
+# always in BR1, and so the only change was whether or not they observed DST....
+# The earliest issue of the SSIM I have is 2/91.  Each issue from then until
+# 9/95 says that DST is observed only in the ten states I quoted from 9/95,
+# along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2
+# (UTC-4)....  The other two time zones given for Brazil are BR3, which is
+# UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is
+# UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's
+# become part of the state of Pernambuco).  The boundary between BR1 and BR2
+# has never been clearly stated.  They've simply been called East and West.
+# However, some conclusions can be drawn from another IATA manual: the Airline
+# Coding Directory, which lists close to 400 airports in Brazil.  For each
+# airport it gives a time zone which is coded to the SSIM.  From that
+# information, I'm led to conclude that the states of Amapa (AP), Ceara (CE),
+# Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do
+# Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST.
+
+# From Paul Eggert (1996-11-22):
+# Let's make the following assumptions:
+#
+# * All data in Shanks are correct through 1990.  In particular,
+#   Shanks was right when he said Acre stopped observing DST in mid-1988.
+# * Areas where Shanks reports DST up to 1990, but the IATA reports no DST
+#   in 1995, stopped observing DST in mid-1990.
+#
+# Under these assumptions Brazil needs 7 entries to cover all the distinct
+# time zone histories since 1970:
+#
+# Noronha (UTC-2), Fortaleza (UTC-3), and Manaus (UTC-4) stopped observing DST
+#	in mid-1990.
+# Maceio (UTC-3) stopped observing DST in mid-1990, but started again mid-1995.
+# Sao Paulo (UTC-3) and Cuiaba (UTC-4) always observed DST.
+# Porto Acre (UTC-5) stopped observing DST in mid-1988.
+
+# From Rodrigo Feher <feher@pobox.com> (1998-01-17):
+# Reading "southamerica" file in timezone 7.55 I've found an
+# error. Line 193 say "Territory of Acre". It is not a territory anymore
+# but a state.

+# TZ zone descriptions
+#
+# From Paul Eggert <eggert@twinsun.com> (1996-08-05):
+#
+# This file contains a table with the following columns:
+# 1.  ISO 3166 2-character country code.  See the file `iso3166.tab'.
+# 2.  Latitude and longitude of the zone's principal location
+#     in ISO 6709 sign-degrees-minutes-seconds format,
+#     either +-DDMM+-DDDMM or +-DDMMSS+-DDDMMSS,
+#     first latitude (+ is north), then longitude (+ is east).
+# 3.  Zone name used in value of TZ environment variable.
+# 4.  Comments; present if and only if the country has multiple rows.
+#     
+# Columns are separated by a single tab.
+# The table is sorted first by country, then an order within the country that
+# (1) makes some geographical sense, and
+# (2) puts the most populous zones first, where that does not contradict (1).
+#
+# Lines beginning with `#' are comments.
