54# From Alex Livingston (1996-11-01):
55# I have heard or read more than once that some resort islands off the coast
56# of Queensland chose to keep observing daylight-saving time even after
57# Queensland ceased to.
58#
59# From Paul Eggert (1996-11-22):
60# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
61# Hamilton) observed DST for two years after the rest of Queensland stopped.
62# Hamilton is the largest, but there is also a Hamilton in Victoria,
63# so use Lindeman.

818# From John Mackin (1991-03-06):
819# We in Australia have _never_ referred to DST as `daylight' time.
820# It is called `summer' time.  Now by a happy coincidence, `summer'
821# and `standard' happen to start with the same letter; hence, the
822# abbreviation does _not_ change...
823# The legislation does not actually define abbreviations, at least
824# in this State, but the abbreviation is just commonly taken to be the
825# initials of the phrase, and the legislation here uniformly uses
826# the phrase `summer time' and does not use the phrase `daylight
827# time'.
828# Announcers on the Commonwealth radio network, the ABC (for Australian
829# Broadcasting Commission), use the phrases `Eastern Standard Time'
830# or `Eastern Summer Time'.  (Note, though, that as I say in the
831# current australasia file, there is really no such thing.)  Announcers
832# on its overseas service, Radio Australia, use the same phrases
833# prefixed by the word `Australian' when referring to local times;
834# time announcements on that service, naturally enough, are made in UTC.

842# From Chuck Soper (2006-06-01):
843# I recently found this Australian government web page on time zones:
844# <http://www.australia.gov.au/about-australia-13time>
845# And this government web page lists time zone names and abbreviations:
846# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml>
847
848# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
849# versus "AEST" etc.:
850#
851# I see the following points of dispute:
852#
853# * How important are unique time zone abbreviations?
854#
855#   Here I tend to agree with the point (most recently made by Chris
856#   Newman) that unique abbreviations should not be essential for proper
857#   operation of software.  We have other instances of ambiguity
858#   (e.g. "IST" denoting both "Israel Standard Time" and "Indian
859#   Standard Time"), and they are not likely to go away any time soon.
860#   In the old days, some software mistakenly relied on unique
861#   abbreviations, but this is becoming less true with time, and I don't
862#   think it's that important to cater to such software these days.
863#
864#   On the other hand, there is another motivation for unambiguous
865#   abbreviations: it cuts down on human confusion.  This is
866#   particularly true for Australia, where "EST" can mean one thing for
867#   time T and a different thing for time T plus 1 second.
868#
869# * Does the relevant legislation indicate which abbreviations should be used?
870#
871#   Here I tend to think that things are a mess, just as they are in
872#   many other countries.  We Americans are currently disagreeing about
873#   which abbreviation to use for the newly legislated Chamorro Standard
874#   Time, for example.
875#
876#   Personally, I would prefer to use common practice; I would like to
877#   refer to legislation only for examples of common practice, or as a
878#   tiebreaker.
879#
880# * Do Australians more often use "Eastern Daylight Time" or "Eastern
881#   Summer Time"?  Do they typically prefix the time zone names with
882#   the word "Australian"?
883#
884#   My own impression is that both "Daylight Time" and "Summer Time" are
885#   common and are widely understood, but that "Summer Time" is more
886#   popular; and that the leading "A" is also common but is omitted more
887#   often than not.  I just used AltaVista advanced search and got the
888#   following count of page hits:
889#
890#     1,103 "Eastern Summer Time" AND domain:au
891#       971 "Australian Eastern Summer Time" AND domain:au
892#       613 "Eastern Daylight Time" AND domain:au
893#       127 "Australian Eastern Daylight Time" AND domain:au
894#
895#   Here "Summer" seems quite a bit more popular than "Daylight",
896#   particularly when we know the time zone is Australian and not US,
897#   say.  The "Australian" prefix seems to be popular for Eastern Summer
898#   Time, but unpopular for Eastern Daylight Time.
899#
900#   For abbreviations, tools like AltaVista are less useful because of
901#   ambiguity.  Many hits are not really time zones, unfortunately, and
902#   many hits denote US time zones and not Australian ones.  But here
903#   are the hit counts anyway:
904#
905#     161,304 "EST" and domain:au
906#      25,156 "EDT" and domain:au
907#      18,263 "AEST" and domain:au
908#      10,416 "AEDT" and domain:au
909#
910#      14,538 "CST" and domain:au
911#       5,728 "CDT" and domain:au
912#         176 "ACST" and domain:au
913#          29 "ACDT" and domain:au
914#
915#       7,539 "WST" and domain:au
916#          68 "AWST" and domain:au
917#
918#   This data suggest that Australians tend to omit the "A" prefix in
919#   practice.  The situation for "ST" versus "DT" is less clear, given
920#   the ambiguities involved.
921#
922# * How do Australians feel about the abbreviations in the tz database?
923#
924#   If you just count Australians on this list, I count 2 in favor and 3
925#   against.  One of the "against" votes (David Keegel) counseled delay,
926#   saying that both AEST/AEDT and EST/EST are widely used and
927#   understood in Australia.
928
929# From Paul Eggert (1995-12-19):
930# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ.
931# Mark Prior writes that his newspaper
932# reports that NSW's fall 1995 change will occur at 2:00,
933# but Robert Elz says it's been 3:00 in Victoria since 1970
934# and perhaps the newspaper's `2:00' is referring to standard time.
935# For now we'll continue to assume 2:00s for changes since 1960.

1066# From Rives McDow (2002-04-09):
1067# The most interesting region I have found consists of three towns on the
1068# southern coast....  South Australia observes daylight saving time; Western
1069# Australia does not.  The two states are one and a half hours apart.  The
1070# residents decided to forget about this nonsense of changing the clock so
1071# much and set the local time 20 hours and 45 minutes from the
1072# international date line, or right in the middle of the time of South
1073# Australia and Western Australia....
1074#
1075# From Paul Eggert (2002-04-09):
1076# This is confirmed by the section entitled

1080# From Alex Livingston (2006-12-07):
1081# ... it was just on four years ago that I drove along the Eyre Highway,
1082# which passes through eastern Western Australia close to the southern
1083# coast of the continent.
1084#
1085# I paid particular attention to the time kept there. There can be no
1086# dispute that UTC+08:45 was considered "the time" from the border
1087# village just inside the border with South Australia to as far west
1088# as just east of Caiguna. There can also be no dispute that Eucla is
1089# the largest population centre in this zone....
1090#
1091# Now that Western Australia is observing daylight saving, the
1092# question arose whether this part of the state would follow suit. I
1093# just called the border village and confirmed that indeed they have,

1096# (2006-12-09):
1097# I personally doubt that either experimentation with daylight saving

1194# From Scott Harrington (2001-08-29):
1195# On KQED's "City Arts and Lectures" program last night I heard an

1197# discussing his book "The Sun in the Church: Cathedrals as Solar
1198# Observatories"[1], and in particular the Shrine of Remembrance[2] located
1199# in Melbourne, Australia.
1200#
1201# Apparently the shrine's main purpose is a beam of sunlight which
1202# illuminates a special spot on the floor at the 11th hour of the 11th day
1203# of the 11th month (Remembrance Day) every year in memory of Australia's
1204# fallen WWI soldiers.  And if you go there on Nov. 11, at 11am local time,
1205# you will indeed see the sunbeam illuminate the special spot at the
1206# expected time.
1207#
1208# However, that is only because of some special mirror contraption that had
1209# to be employed, since due to daylight savings time, the true solar time of
1210# the remembrance moment occurs one hour later (or earlier?).  Perhaps
1211# someone with more information on this jury-rig can tell us more.

1318# Lord Howe Island summer time in 2000/2001 will commence on the same

1320# Lord Howe Island Board (controlling authority for the Island) is
1321# seeking the community's views on various options for summer time
1322# arrangements on the Island, e.g. advance clocks by 1 full hour
1323# instead of only 30 minutes.  [Dependent] on the wishes of residents
1324# the Board may approach the NSW government to change the existing

1326# however always coincide with the rest of NSW.
1327
1328# From James Lonergan, Secretary, Lord Howe Island Board (2000-10-25):
1329# Lord Howe Island advances clocks by 30 minutes during DST in NSW and retards

1331# introduced in NSW, the "changeover" time on the Island has been 02:00 as
1332# shown on clocks on LHI. I guess this means that for 30 minutes at the start
1333# of DST, LHI is actually 1 hour ahead of the rest of NSW.

1511# Pitcairn
1512
1513# From Rives McDow (1999-11-08):
1514# A Proclamation was signed by the Governor of Pitcairn on the 27th March 1998
1515# with regard to Pitcairn Standard Time.  The Proclamation is as follows.
1516#
1517#	The local time for general purposes in the Islands shall be
1518#	Co-ordinated Universal time minus 8 hours and shall be known
1519#	as Pitcairn Standard Time.
1520#
1521# ... I have also seen Pitcairn listed as UTC minus 9 hours in several
1522# references, and can only assume that this was an error in interpretation
1523# somehow in light of this proclamation.
1524
1525# From Rives McDow (1999-11-09):
1526# The Proclamation regarding Pitcairn time came into effect on 27 April 1998
1527# ... at midnight.
1528
1529# From Howie Phelps (1999-11-10), who talked to a Pitcairner via shortwave:
1530# Betty Christian told me yesterday that their local time is the same as
1531# Pacific Standard Time. They used to be 1/2 hour different from us here in
1532# Sacramento but it was changed a couple of years ago.

1538# that in 1879 the King of Samoa decided to change
1539# ``the date in his kingdom from the Antipodean to the American system,
1540# ordaining -- by a masterpiece of diplomatic flattery -- that
1541# the Fourth of July should be celebrated twice in that year.''

1544# Tonga
1545
1546# From Paul Eggert (1996-01-22):
1547# Today's _Wall Street Journal_ (p 1) reports that ``Tonga has been plotting
1548# to sneak ahead of [New Zealanders] by introducing daylight-saving time.''
1549# Since Kiribati has moved the Date Line it's not clear what Tonga will do.

1552# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
1553# How Tonga became `The Land where Time Begins'
1554# </a>:
1555
1556# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
1557# 12 hours and 20 minutes ahead of GMT.  When New Zealand adjusted its
1558# standard time in 1940s, Tonga had the choice of subtracting from its
1559# local time to come on the same standard time as New Zealand or of
1560# advancing its time to maintain the differential of 13 degrees
1561# (approximately 50 minutes ahead of New Zealand time).
1562#
1563# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1564# Tungi, preferred to ensure Tonga's title as the land where time
1565# begins, the Legislative Assembly approved the latter change.
1566#
1567# But some of the older, more conservative members from the outer
1568# islands objected. "If at midnight on Dec. 31, we move ahead 40
1569# minutes, as your Royal Highness wishes, what becomes of the 40
1570# minutes we have lost?"
1571#
1572# The Crown Prince, presented an unanswerable argument: "Remember that
1573# on the World Day of Prayer, you would be the first people on Earth
1574# to say your prayers in the morning."
1575
1576# From Paul Eggert (2006-03-22):
1577# Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell.
1578
1579# From Eric Ulevik (1999-05-03):
1580# Tonga's director of tourism, who is also secretary of the National Millenium
1581# Committee, has a plan to get Tonga back in front.
1582# He has proposed a one-off move to tropical daylight saving for Tonga from
1583# October to March, which has won approval in principle from the Tongan
1584# Government.
1585

1587# * Tonga will introduce DST in November

1594# I have not been able to find exact dates for the transition in November
1595# yet. By reading this article it seems like Fiji will be 14 hours ahead

1640# Saturday, the 14th [of October, 1950] -- ...  The time was all the

1654# The International Date Line
1655
1656# From Gwillim Law (2000-01-03):
1657#
1658# The International Date Line is not defined by any international standard,
1659# convention, or treaty.  Mapmakers are free to draw it as they please.
1660# Reputable mapmakers will simply ensure that every point of land appears on
1661# the correct side of the IDL, according to the date legally observed there.
1662#
1663# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1664# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1665# to the east side of the Phoenix and Line Islands), I suppose that most
1666# mapmakers redrew the IDL following the boundary of Kiribati.  Even that line
1667# has a rather arbitrary nature.  The straight-line boundaries between Pacific
1668# island nations that are shown on many maps are based on an international
1669# convention, but are not legally binding national borders.... The date is
1670# governed by the IDL; therefore, even on the high seas, there may be some
1671# places as late as fourteen hours later than UTC.  And, since the IDL is not
1672# an international standard, there are some places on the high seas where the
1673# correct date is ambiguous.
1674
1675# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
1676# Before 1920, all ships kept local apparent time on the high seas by setting
1677# their clocks at night or at the morning sight so that, given the ship's
1678# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
1679# meridian (12 o'clock = local apparent noon).  During 1917, at the
1680# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
1681# ships, both military and civilian, should adopt hourly standard time zones
1682# on the high seas.  Whenever a ship was within the territorial waters of any
1683# nation it would use that nation's standard time.  The captain was permitted
1684# to change his ship's clocks at a time of his choice following his ship's
1685# entry into another zone time--he often chose midnight.  These zones were
1686# adopted by all major fleets between 1920 and 1925 but not by many
1687# independent merchant ships until World War II.
