+
+# 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

+#
+# An Order made under the Summer Time (Isle of Man) Act, 1916

+#
+# 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.

+# - 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

+#
+# - 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

+#
+# - 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

+#
+# - 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

+#
+# - The Defence (Summer Time) Regulations, 1939, S.R.&O. 1939, No. 1379

+#
+# - 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

+# which continues throughout the rest of the year.
+#
+# - S.R.&O. 1942, No. 506
+#
+# Another Order amending the Defence (Summer Time) Regulations, 1939.

+# - 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

+# From Chris Carrier <72157.3334@CompuServe.COM> (1996-12-02):
+# On 1929-10-01 the Soviet Union instituted an ``Eternal Calendar''
+# with 30-day months plus 5 holidays, with a 5-day week.
+# On 1931-12-01 it changed to a 6-day week; in 1934 it reverted to the
+# Gregorian calendar while retaining the 6-day week; on 1940-06-27 it
+# reverted to the 7-day week.  With the 6-day week the usual days
+# off were the 6th, 12th, 18th, 24th and 30th of the month.
+# (Source: Evitiar Zerubavel, _The Seven Day Circle_)
+#
+# From Paul Eggert <eggert@twinsun.com> (1996-11-22):
+# Except for Moscow after 1919-07-01, I invented the time zone abbreviations,
+# and (unless otherwise specified) guessed what happened after 1991.
+# Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,
+# are from Andrey A. Chernov.  The rest is from Shanks and the IATA.
+#
+# From Andrey A. Chernov <ache@nagual.ru> (1996-10-04):
+# `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.
+#
+# From Chris Carrier <72157.3334@CompuServe.COM> (1996-10-30):
+# According to a friend of mine who rode the Trans-Siberian Railroad from
+# Moscow to Irkutsk in 1995, public air and rail transport in Russia ...
+# still follows Moscow time, no matter where in Russia it is located.

+#
+# 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).)

+# '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.

+# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the

+# 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.
