41# From Alex Livingston <alex@agsm.unsw.edu.au> (1996-11-01):
42# I have heard or read more than once that some resort islands off the coast
43# of Queensland chose to keep observing daylight-saving time even after
44# Queensland ceased to.
45#
46# From Paul Eggert (1996-11-22):
47# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
48# Hamilton) observed DST for two years after the rest of Queensland stopped.
49# Hamilton is the largest, but there is also a Hamilton in Victoria,
50# so use Lindeman.

537# <a href="http://www.dstc.qut.edu.au/DST/marg/daylight.html">
538# Australia's Daylight Saving Times
539# </a>, by Margaret Turner, summarizes daylight saving issues in Australia.
540
541# From John Mackin (1991-03-06):
542# We in Australia have _never_ referred to DST as `daylight' time.
543# It is called `summer' time.  Now by a happy coincidence, `summer'
544# and `standard' happen to start with the same letter; hence, the
545# abbreviation does _not_ change...
546# The legislation does not actually define abbreviations, at least
547# in this State, but the abbreviation is just commonly taken to be the
548# initials of the phrase, and the legislation here uniformly uses
549# the phrase `summer time' and does not use the phrase `daylight
550# time'.
551# Announcers on the Commonwealth radio network, the ABC (for Australian
552# Broadcasting Commission), use the phrases `Eastern Standard Time'
553# or `Eastern Summer Time'.  (Note, though, that as I say in the
554# current australasia file, there is really no such thing.)  Announcers
555# on its overseas service, Radio Australia, use the same phrases
556# prefixed by the word `Australian' when referring to local times;
557# time announcements on that service, naturally enough, are made in UTC.
558
559# From Arthur David Olson (1992-03-08):
560# Given the above, what's chosen for year-round use is:
561#	CST	for any place operating at a GMTOFF of 9:30
562#	WST	for any place operating at a GMTOFF of 8:00
563#	EST	for any place operating at a GMTOFF of 10:00
564
565# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
566# versus "AEST" etc.:
567#
568# I see the following points of dispute:
569#
570# * How important are unique time zone abbreviations?
571#
572#   Here I tend to agree with the point (most recently made by Chris
573#   Newman) that unique abbreviations should not be essential for proper
574#   operation of software.  We have other instances of ambiguity
575#   (e.g. "IST" denoting both "Israel Standard Time" and "Indian
576#   Standard Time"), and they are not likely to go away any time soon.
577#   In the old days, some software mistakenly relied on unique
578#   abbreviations, but this is becoming less true with time, and I don't
579#   think it's that important to cater to such software these days.
580#
581#   On the other hand, there is another motivation for unambiguous
582#   abbreviations: it cuts down on human confusion.  This is
583#   particularly true for Australia, where "EST" can mean one thing for
584#   time T and a different thing for time T plus 1 second.
585#
586# * Does the relevant legislation indicate which abbreviations should be used?
587#
588#   Here I tend to think that things are a mess, just as they are in
589#   many other countries.  We Americans are currently disagreeing about
590#   which abbreviation to use for the newly legislated Chamorro Standard
591#   Time, for example.
592#
593#   Personally, I would prefer to use common practice; I would like to
594#   refer to legislation only for examples of common practice, or as a
595#   tiebreaker.
596#
597# * Do Australians more often use "Eastern Daylight Time" or "Eastern
598#   Summer Time"?  Do they typically prefix the time zone names with
599#   the word "Australian"?
600#
601#   My own impression is that both "Daylight Time" and "Summer Time" are
602#   common and are widely understood, but that "Summer Time" is more
603#   popular; and that the leading "A" is also common but is omitted more
604#   often than not.  I just used AltaVista advanced search and got the
605#   following count of page hits:
606#
607#     1,103 "Eastern Summer Time" AND domain:au
608#       971 "Australian Eastern Summer Time" AND domain:au
609#       613 "Eastern Daylight Time" AND domain:au
610#       127 "Australian Eastern Daylight Time" AND domain:au
611#
612#   Here "Summer" seems quite a bit more popular than "Daylight",
613#   particularly when we know the time zone is Australian and not US,
614#   say.  The "Australian" prefix seems to be popular for Eastern Summer
615#   Time, but unpopular for Eastern Daylight Time.
616#
617#   For abbreviations, tools like AltaVista are less useful because of
618#   ambiguity.  Many hits are not really time zones, unfortunately, and
619#   many hits denote US time zones and not Australian ones.  But here
620#   are the hit counts anyway:
621#
622#     161,304 "EST" and domain:au
623#      25,156 "EDT" and domain:au
624#      18,263 "AEST" and domain:au
625#      10,416 "AEDT" and domain:au
626#
627#      14,538 "CST" and domain:au
628#       5,728 "CDT" and domain:au
629#         176 "ACST" and domain:au
630#          29 "ACDT" and domain:au
631#
632#       7,539 "WST" and domain:au
633#          68 "AWST" and domain:au
634#
635#   This data suggest that Australians tend to omit the "A" prefix in
636#   practice.  The situation for "ST" versus "DT" is less clear, given
637#   the ambiguities involved.
638#
639# * How do Australians feel about the abbreviations in the tz database?
640#
641#   If you just count Australians on this list, I count 2 in favor and 3
642#   against.  One of the "against" votes (David Keegel) counseled delay,
643#   saying that both AEST/AEDT and EST/EST are widely used and
644#   understood in Australia.
645
646# From Paul Eggert (1995-12-19):
647# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
648# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
649# reports that NSW's fall 1995 change will occur at 2:00,
650# but Robert Elz says it's been 3:00 in Victoria since 1970
651# and perhaps the newspaper's `2:00' is referring to standard time.
652# For now we'll continue to assume 2:00s for changes since 1960.

759
760# From Rives McDow (2002-04-09):
761# The most interesting region I have found consists of three towns on the
762# southern coast of Australia, population 10 at last report, along with
763# 50,000 sheep, about 100 kilometers long and 40 kilometers into the
764# continent.  The primary town is Madura, with the other towns being
765# Mundrabilla and Eucla.  According to the sheriff of Madura, the
766# residents got tired of having to change the time so often, as they are
767# located in a strip overlapping the border of South Australia and Western
768# Australia.  South Australia observes daylight saving time; Western
769# Australia does not.  The two states are one and a half hours apart.  The
770# residents decided to forget about this nonsense of changing the clock so
771# much and set the local time 20 hours and 45 minutes from the
772# international date line, or right in the middle of the time of South
773# Australia and Western Australia.  As it only affects about 10 people and
774# tourists staying at the Madura Motel, it has never really made as big an
775# impact as Broken Hill.  However, as tourist visiting there or anyone
776# calling the local sheriff will attest, they do keep time in this way.
777#
778# From Paul Eggert (2002-04-09):
779# This is confirmed by the section entitled
780# "What's the deal with time zones???" in
781# <http://www.earthsci.unimelb.edu.au/~awatkins/null.html>,
782# which says a few other things:
783#
784# * Border Village, SA also is 45 minutes ahead of Perth.
785# * The locals call this time zone "central W.A. Time" (presumably "CWAT").
786# * The locals also call Western Australia time "Perth time".
787#
788# It's not clear from context whether everyone in Western Australia
789# knows of this naming convention, or whether it's just the people in
790# this subregion.

893# From Scott Harrington (2001-08-29):
894# On KQED's "City Arts and Lectures" program last night I heard an
895# interesting story about daylight savings time.  Dr. John Heilbron was
896# discussing his book "The Sun in the Church: Cathedrals as Solar
897# Observatories"[1], and in particular the Shrine of Remembrance[2] located
898# in Melbourne, Australia.
899#
900# Apparently the shrine's main purpose is a beam of sunlight which
901# illuminates a special spot on the floor at the 11th hour of the 11th day
902# of the 11th month (Remembrance Day) every year in memory of Australia's
903# fallen WWI soldiers.  And if you go there on Nov. 11, at 11am local time,
904# you will indeed see the sunbeam illuminate the special spot at the
905# expected time.
906#
907# However, that is only because of some special mirror contraption that had
908# to be employed, since due to daylight savings time, the true solar time of
909# the remembrance moment occurs one hour later (or earlier?).  Perhaps
910# someone with more information on this jury-rig can tell us more.

921#	In Australia, time is not legislated federally, but rather by the

1172# <http://radiodx.com/spdxr/KMTH.htm> (2002-12-31):
1173# For the past two months we've been on what is known as Daylight
1174# Saving Time.  This time has put us on air at 5am in the morning,
1175# your time down there in New Zealand.  Starting September 2, 1956
1176# we'll again go back to Standard Time.  This'll mean that we'll go to
1177# air at 6am your time.

1179# From Paul Eggert (2003-03-23):
1180# We don't know the date of that quote, but we'll guess they

1187# From Rives McDow (1999-11-08):
1188# A Proclamation was signed by the Governor of Pitcairn on the 27th March 1998
1189# with regard to Pitcairn Standard Time.  The Proclamation is as follows.
1190#
1191#	The local time for general purposes in the Islands shall be
1192#	Co-ordinated Universal time minus 8 hours and shall be known
1193#	as Pitcairn Standard Time.
1194#
1195# ... I have also seen Pitcairn listed as UTC minus 9 hours in several
1196# references, and can only assume that this was an error in interpretation
1197# somehow in light of this proclamation.
1198
1199# From Rives McDow (1999-11-09):
1200# The Proclamation regarding Pitcairn time came into effect on 27 April 1998

1203# From Howie Phelps (1999-11-10), who talked to a Pitcairner via shortwave:

1218# Tonga
1219
1220# From Paul Eggert (1996-01-22):
1221# Today's _Wall Street Journal_ (p 1) reports that ``Tonga has been plotting
1222# to sneak ahead of [New Zealanders] by introducing daylight-saving time.''
1223# Since Kiribati has moved the Date Line it's not clear what Tonga will do.

1225# Don Mundell writes in the 1997-02-20 Tonga Chronicle
1226# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
1227# How Tonga became `The Land where Time Begins'
1228# </a>:
1229
1230# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
1231# 12 hours and 20 minutes ahead of GMT.  When New Zealand adjusted its
1232# standard time in 1940s, Tonga had the choice of subtracting from its
1233# local time to come on the same standard time as New Zealand or of
1234# advancing its time to maintain the differential of 13 degrees
1235# (approximately 50 minutes ahead of New Zealand time).
1236#
1237# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1238# Tungi, preferred to ensure Tonga's title as the land where time
1239# begins, the Legislative Assembly approved the latter change.
1240#
1241# But some of the older, more conservative members from the outer
1242# islands objected. "If at midnight on Dec. 31, we move ahead 40
1243# minutes, as your Royal Highness wishes, what becomes of the 40
1244# minutes we have lost?"
1245#
1246# The Crown Prince, presented an unanswerable argument: "Remember that
1247# on the World Day of Prayer, you would be the first people on Earth
1248# to say your prayers in the morning."
1249
1250# From Paul Eggert (1999-08-12):
1251# Shanks says the transition was on 1968-10-01; go with Mundell.
1252
1253# From Eric Ulevik (1999-05-03):
1254# Tonga's director of tourism, who is also secretary of the National Millenium
1255# Committee, has a plan to get Tonga back in front.
1256# He has proposed a one-off move to tropical daylight saving for Tonga from
1257# October to March, which has won approval in principle from the Tongan
1258# Government.

1268# I have not been able to find exact dates for the transition in November

1313#
1314# Saturday, the 14th [of October, 1950] -- ...  The time was all the
1315# more confusing at that point, because we had crossed the
1316# International Date Line, thus getting two Sundays.  Furthermore, we
1317# discovered that Wake Island had two hours of daylight saving time

1328# The International Date Line
1329
1330# From Gwillim Law (2000-01-03):
1331#
1332# The International Date Line is not defined by any international standard,
1333# convention, or treaty.  Mapmakers are free to draw it as they please.
1334# Reputable mapmakers will simply ensure that every point of land appears on
1335# the correct side of the IDL, according to the date legally observed there.
1336#
1337# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1338# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1339# to the east side of the Phoenix and Line Islands), I suppose that most
1340# mapmakers redrew the IDL following the boundary of Kiribati.  Even that line
1341# has a rather arbitrary nature.  The straight-line boundaries between Pacific
1342# island nations that are shown on many maps are based on an international
1343# convention, but are not legally binding national borders.
1344#
1345# An Anglo-French Conference on Time-Keeping at Sea (June, 1917) agreed that
1346# legal time on the high seas would be zone time, i.e., the standard time at
1347# the nearest meridian that is a multiple of fifteen degrees.  The date is
1348# governed by the IDL; therefore, even on the high seas, there may be some
1349# places as late as fourteen hours later than UTC.  And, since the IDL is not
1350# an international standard, there are some places on the high seas where the
1351# correct date is ambiguous.
1352
1353# From Paul Eggert, using references suggested by Oscar van Vlijmen

1356# The American Practical Navigator (2002)
1357# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187>
1358# talks only about the 180-degree meridian with respect to ships in
1359# international waters; it ignores the international date line.
