# From Alex Livingston <alex@agsm.unsw.edu.au> (1996-11-01):
# I have heard or read more than once that some resort islands off the coast
# of Queensland chose to keep observing daylight-saving time even after
# Queensland ceased to.
#
# From Paul Eggert (1996-11-22):
# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
# Hamilton) observed DST for two years after the rest of Queensland stopped.
# Hamilton is the largest, but there is also a Hamilton in Victoria,
# so use Lindeman.

# <a href="http://www.dstc.qut.edu.au/DST/marg/daylight.html">
# Australia's Daylight Saving Times
# </a>, by Margaret Turner, summarizes daylight saving issues in 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 (1992-03-08):
# 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 (2001-04-05), summarizing a long discussion about "EST"
# versus "AEST" etc.:
#
# I see the following points of dispute:
#
# * How important are unique time zone abbreviations?
#
#   Here I tend to agree with the point (most recently made by Chris
#   Newman) that unique abbreviations should not be essential for proper
#   operation of software.  We have other instances of ambiguity
#   (e.g. "IST" denoting both "Israel Standard Time" and "Indian
#   Standard Time"), and they are not likely to go away any time soon.
#   In the old days, some software mistakenly relied on unique
#   abbreviations, but this is becoming less true with time, and I don't
#   think it's that important to cater to such software these days.
#
#   On the other hand, there is another motivation for unambiguous
#   abbreviations: it cuts down on human confusion.  This is
#   particularly true for Australia, where "EST" can mean one thing for
#   time T and a different thing for time T plus 1 second.
#
# * Does the relevant legislation indicate which abbreviations should be used?
#
#   Here I tend to think that things are a mess, just as they are in
#   many other countries.  We Americans are currently disagreeing about
#   which abbreviation to use for the newly legislated Chamorro Standard
#   Time, for example.
#
#   Personally, I would prefer to use common practice; I would like to
#   refer to legislation only for examples of common practice, or as a
#   tiebreaker.
#
# * Do Australians more often use "Eastern Daylight Time" or "Eastern
#   Summer Time"?  Do they typically prefix the time zone names with
#   the word "Australian"?
#
#   My own impression is that both "Daylight Time" and "Summer Time" are
#   common and are widely understood, but that "Summer Time" is more
#   popular; and that the leading "A" is also common but is omitted more
#   often than not.  I just used AltaVista advanced search and got the
#   following count of page hits:
#
#     1,103 "Eastern Summer Time" AND domain:au
#       971 "Australian Eastern Summer Time" AND domain:au
#       613 "Eastern Daylight Time" AND domain:au
#       127 "Australian Eastern Daylight Time" AND domain:au
#
#   Here "Summer" seems quite a bit more popular than "Daylight",
#   particularly when we know the time zone is Australian and not US,
#   say.  The "Australian" prefix seems to be popular for Eastern Summer
#   Time, but unpopular for Eastern Daylight Time.
#
#   For abbreviations, tools like AltaVista are less useful because of
#   ambiguity.  Many hits are not really time zones, unfortunately, and
#   many hits denote US time zones and not Australian ones.  But here
#   are the hit counts anyway:
#
#     161,304 "EST" and domain:au
#      25,156 "EDT" and domain:au
#      18,263 "AEST" and domain:au
#      10,416 "AEDT" and domain:au
#
#      14,538 "CST" and domain:au
#       5,728 "CDT" and domain:au
#         176 "ACST" and domain:au
#          29 "ACDT" and domain:au
#
#       7,539 "WST" and domain:au
#          68 "AWST" and domain:au
#
#   This data suggest that Australians tend to omit the "A" prefix in
#   practice.  The situation for "ST" versus "DT" is less clear, given
#   the ambiguities involved.
#
# * How do Australians feel about the abbreviations in the tz database?
#
#   If you just count Australians on this list, I count 2 in favor and 3
#   against.  One of the "against" votes (David Keegel) counseled delay,
#   saying that both AEST/AEDT and EST/EST are widely used and
#   understood in Australia.

# 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.

# discussing his book "The Sun in the Church: Cathedrals as Solar

# in Melbourne, Australia.
#
# Apparently the shrine's main purpose is a beam of sunlight which
# illuminates a special spot on the floor at the 11th hour of the 11th day
# of the 11th month (Remembrance Day) every year in memory of Australia's
# fallen WWI soldiers.  And if you go there on Nov. 11, at 11am local time,
# you will indeed see the sunbeam illuminate the special spot at the
# expected time.
#
# However, that is only because of some special mirror contraption that had
# to be employed, since due to daylight savings time, the true solar time of
# the remembrance moment occurs one hour later (or earlier?).  Perhaps
# someone with more information on this jury-rig can tell us more.

# New South Wales and subjurisdictions have their own ideas of a fun time.
# Based on law library research by John Mackin (john@basser.cs.su.oz),
# who notes:
#	In Australia, time is not legislated federally, but rather by the
#	individual states.  Thus, while such terms as ``Eastern Standard Time''
#	[I mean, of course, Australian EST, not any other kind] are in common
#	use, _they have NO REAL MEANING_, as they are not defined in the
#	legislation.  This is very important to understand.

# clocks by 30 minutes when DST finishes. Since DST was most recently
# introduced in NSW, the "changeover" time on the Island has been 02:00 as
# shown on clocks on LHI. I guess this means that for 30 minutes at the start
# of DST, LHI is actually 1 hour ahead of the rest of NSW.

# From Paul Eggert (2001-02-09):
# For Lord Howe dates we use Shanks through 1989, and Lonergan thereafter.
# For times we use Lonergan.

# New Zealand

# 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.

# 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 (1999-10-29):
# Shanks gives no time data for Chatham; usno1989 says it's +12:45,
# usno1995 says it's +12:45/+13:45, and IATA SSIM (1991/1999)
# gives the NZ rules but with transitions at 2:45 local standard time.
# Guess that they have been in lock-step with NZ since 1990.

# Fiji

# Howse writes (p 153) that in 1879 the British governor of Fiji
# enacted an ordinance standardizing the islands on Antipodean Time
# instead of the American system (which was one day behind).

# From Rives McDow (1998-10-08):
# Fiji will introduce DST effective 0200 local time, 1998-11-01
# until 0300 local time 1999-02-28.  Each year the DST period will
# be from the first Sunday in November until the last Sunday in February.

# From Paul Eggert (2000-01-08):
# IATA SSIM (1999-09) says DST ends 0100 local time.  Go with McDow.

# From the BBC World Service (1998-10-31 11:32 UTC):
# The Fijiian government says the main reasons for the time change is to
# improve productivity and reduce road accidents.  But correspondents say it
# also hopes the move will boost Fiji's ability to compete with other pacific
# islands in the effort to attract tourists to witness the dawning of the new
# millenium.

# as part of the competition to be first into the 21st century.

# In comp.risks 14.87 (26 August 1993), Peter Neumann writes:
# I wonder what happened in Kwajalein, where there was NO Friday,

# N Mariana Is, Guam

# Howse writes (p 153) ``The Spaniards, on the other hand, reached the
# Philippines and the Ladrones from America,'' and implies that the Ladrones
# (now called the Marianas) kept American date for quite some time.
# For now, we assume the Ladrones switched at the same time as the Philippines;
# see Asia/Manila.

# US Public Law 106-564 (2000-12-23) made UTC+10 the official standard time,

#
# Shanks writes that Truk switched from UTC+10 to UTC+11 on 1978-10-01;
# ignore this for now.

# Pitcairn

# From Rives McDow (1999-11-08):
# A Proclamation was signed by the Governor of Pitcairn on the 27th March 1998
# with regard to Pitcairn Standard Time.  The Proclamation is as follows.
#
#	The local time for general purposes in the Islands shall be
#	Co-ordinated Universal time minus 8 hours and shall be known
#	as Pitcairn Standard Time.
#
# ... I have also seen Pitcairn listed as UTC minus 9 hours in several
# references, and can only assume that this was an error in interpretation
# somehow in light of this proclamation.

# From Rives McDow (1999-11-09):
# The Proclamation regarding Pitcairn time came into effect on 27 April 1998
# ... at midnight.

# From Howie Phelps (1999-11-10), who talked to a Pitcairner via shortwave:
# Betty Christian told me yesterday that their local time is the same as
# Pacific Standard Time. They used to be 1/2 hour different from us here in
# Sacramento but it was changed a couple of years ago.


# Samoa

# Howse writes (p 153, citing p 10 of the 1883-11-18 New York Herald)

# Tonga

# From Paul Eggert (1996-01-22):
# Today's _Wall Street Journal_ (p 1) reports that ``Tonga has been plotting
# to sneak ahead of [New Zealanders] by introducing daylight-saving time.''
# Since Kiribati has moved the Date Line it's not clear what Tonga will do.

# Don Mundell writes in the 1997-02-20 Tonga Chronicle
# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
# How Tonga became `The Land where Time Begins'
# </a>:

# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
# 12 hours and 20 minutes ahead of GMT.  When New Zealand adjusted its
# standard time in 1940s, Tonga had the choice of subtracting from its
# local time to come on the same standard time as New Zealand or of
# advancing its time to maintain the differential of 13 degrees
# (approximately 50 minutes ahead of New Zealand time).
#
# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
# Tungi, preferred to ensure Tonga's title as the land where time
# begins, the Legislative Assembly approved the latter change.
#
# But some of the older, more conservative members from the outer
# islands objected. "If at midnight on Dec. 31, we move ahead 40
# minutes, as your Royal Highness wishes, what becomes of the 40
# minutes we have lost?"
#
# The Crown Prince, presented an unanswerable argument: "Remember that
# on the World Day of Prayer, you would be the first people on Earth
# to say your prayers in the morning."

# From Paul Eggert (1999-08-12):
# Shanks says the transition was on 1968-10-01; go with Mundell.

# From Eric Ulevik (1999-05-03):
# Tonga's director of tourism, who is also secretary of the National Millenium
# Committee, has a plan to get Tonga back in front.
# He has proposed a one-off move to tropical daylight saving for Tonga from
# October to March, which has won approval in principle from the Tongan
# Government.

# From Steffen Thorsen [straen@thorsen.priv.no] (1999-09-09):
# * Tonga will introduce DST in November
#
# I was given this link by John Letts <johnletts@earthlink.net>:
# <a hef="http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm">
# http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm
# </a>
#
# I have not been able to find exact dates for the transition in November
# yet. By reading this article it seems like Fiji will be 14 hours ahead
# of UTC as well, but as far as I know Fiji will only be 13 hours ahead
# (12 + 1 hour DST).

# From Arthur David Olson [arthur_david_olson@nih.gov] (1999-09-20):
# According to <a href="http://www.tongaonline.com/news/sept1799.html>
# http://www.tongaonline.com/news/sept1799.html
# </a>:
# "Daylight Savings Time will take effect on Oct. 2 through April 15, 2000
# and annually thereafter from the first Saturday in October through the
# third Saturday of April.  Under the system approved by Privy Council on
# Sept. 10, clocks must be turned ahead one hour on the opening day and
# set back an hour on the closing date."
# Alas, no indication of the time of day.

# From Rives McDow (1999-10-06):
# Tonga started its Daylight Saving on Saturday morning October 2nd at 0200am.
# Daylight Saving ends on April 16 at 0300am which is Sunday morning.

# From Steffen Thorsen (2000-10-31):
# Back in March I found a notice on the website http://www.tongaonline.com
# that Tonga changed back to standard time one month early, on March 19
# instead of the original reported date April 16. Unfortunately, the article
# is no longer available on the site, and I did not make a copy of the
# text, and I have forgotten to report it here.
# (Original URL was: http://www.tongaonline.com/news/march162000.htm )

# From Rives McDow (2000-12-01):
# Tonga is observing DST as of 2000-11-04 and will stop on 2001-01-27.

# From Sione Moala-Mafi (2001-09-20) via Rives McDow:
# At 2:00am on the first Sunday of November, the standard time in the Kingdom
# shall be moved forward by one hour to 3:00am.  At 2:00am on the last Sunday
# of January the standard time in the Kingdom shall be moved backward by one
# hour to 1:00am.

# The International Date Line

# From Gwillim Law (2000-01-03):
#
# The International Date Line is not defined by any international standard,
# convention, or treaty.  Mapmakers are free to draw it as they please.
# Reputable mapmakers will simply ensure that every point of land appears on
# the correct side of the IDL, according to the date legally observed there.
#
# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
# to the east side of the Phoenix and Line Islands), I suppose that most
# mapmakers redrew the IDL following the boundary of Kiribati.  Even that line
# has a rather arbitrary nature.  The straight-line boundaries between Pacific
# island nations that are shown on many maps are based on an international
# convention, but are not legally binding national borders.
#
# An Anglo-French Conference on Time-Keeping at Sea (June, 1917) agreed that
# legal time on the high seas would be zone time, i.e., the standard time at
# the nearest meridian that is a multiple of fifteen degrees.  The date is
# governed by the IDL; therefore, even on the high seas, there may be some
# places as late as fourteen hours later than UTC.  And, since the IDL is not
# an international standard, there are some places on the high seas where the
# correct date is ambiguous.
