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

842# From John Mackin (1991-03-06):
843# We in Australia have _never_ referred to DST as `daylight' time.
844# It is called `summer' time. Now by a happy coincidence, `summer'
845# and `standard' happen to start with the same letter; hence, the
846# abbreviation does _not_ change...
847# The legislation does not actually define abbreviations, at least
848# in this State, but the abbreviation is just commonly taken to be the
849# initials of the phrase, and the legislation here uniformly uses
850# the phrase `summer time' and does not use the phrase `daylight
851# time'.
852# Announcers on the Commonwealth radio network, the ABC (for Australian
853# Broadcasting Commission), use the phrases `Eastern Standard Time'
854# or `Eastern Summer Time'. (Note, though, that as I say in the
855# current australasia file, there is really no such thing.) Announcers
856# on its overseas service, Radio Australia, use the same phrases
857# prefixed by the word `Australian' when referring to local times;
858# time announcements on that service, naturally enough, are made in UTC.

984263bc
MD
872# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
873# versus "AEST" etc.:
874#
875# I see the following points of dispute:
876#
877# * How important are unique time zone abbreviations?
878#
879# Here I tend to agree with the point (most recently made by Chris
880# Newman) that unique abbreviations should not be essential for proper
881# operation of software. We have other instances of ambiguity
882# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
883# Standard Time"), and they are not likely to go away any time soon.
884# In the old days, some software mistakenly relied on unique
885# abbreviations, but this is becoming less true with time, and I don't
886# think it's that important to cater to such software these days.
887#
888# On the other hand, there is another motivation for unambiguous
889# abbreviations: it cuts down on human confusion. This is
890# particularly true for Australia, where "EST" can mean one thing for
891# time T and a different thing for time T plus 1 second.
892#
893# * Does the relevant legislation indicate which abbreviations should be used?
894#
895# Here I tend to think that things are a mess, just as they are in
896# many other countries. We Americans are currently disagreeing about
897# which abbreviation to use for the newly legislated Chamorro Standard
898# Time, for example.
899#
900# Personally, I would prefer to use common practice; I would like to
901# refer to legislation only for examples of common practice, or as a
902# tiebreaker.
903#
904# * Do Australians more often use "Eastern Daylight Time" or "Eastern
905# Summer Time"? Do they typically prefix the time zone names with
906# the word "Australian"?
907#
908# My own impression is that both "Daylight Time" and "Summer Time" are
909# common and are widely understood, but that "Summer Time" is more
910# popular; and that the leading "A" is also common but is omitted more
911# often than not. I just used AltaVista advanced search and got the
912# following count of page hits:
913#
914# 1,103 "Eastern Summer Time" AND domain:au
915# 971 "Australian Eastern Summer Time" AND domain:au
916# 613 "Eastern Daylight Time" AND domain:au
917# 127 "Australian Eastern Daylight Time" AND domain:au
918#
919# Here "Summer" seems quite a bit more popular than "Daylight",
920# particularly when we know the time zone is Australian and not US,
921# say. The "Australian" prefix seems to be popular for Eastern Summer
922# Time, but unpopular for Eastern Daylight Time.
923#
924# For abbreviations, tools like AltaVista are less useful because of
925# ambiguity. Many hits are not really time zones, unfortunately, and
926# many hits denote US time zones and not Australian ones. But here
927# are the hit counts anyway:
928#
929# 161,304 "EST" and domain:au
930# 25,156 "EDT" and domain:au
931# 18,263 "AEST" and domain:au
932# 10,416 "AEDT" and domain:au
933#
934# 14,538 "CST" and domain:au
935# 5,728 "CDT" and domain:au
936# 176 "ACST" and domain:au
937# 29 "ACDT" and domain:au
938#
939# 7,539 "WST" and domain:au
940# 68 "AWST" and domain:au
941#
942# This data suggest that Australians tend to omit the "A" prefix in
943# practice. The situation for "ST" versus "DT" is less clear, given
944# the ambiguities involved.
945#
946# * How do Australians feel about the abbreviations in the tz database?
947#
948# If you just count Australians on this list, I count 2 in favor and 3
949# against. One of the "against" votes (David Keegel) counseled delay,
950# saying that both AEST/AEDT and EST/EST are widely used and
951# understood in Australia.

956# reports that NSW's fall 1995 change will occur at 2:00,
957# but Robert Elz says it's been 3:00 in Victoria since 1970

1221# discussing his book "The Sun in the Church: Cathedrals as Solar
1222# Observatories"[1], and in particular the Shrine of Remembrance[2] located
1223# in Melbourne, Australia.
1224#
1225# Apparently the shrine's main purpose is a beam of sunlight which
1226# illuminates a special spot on the floor at the 11th hour of the 11th day
1227# of the 11th month (Remembrance Day) every year in memory of Australia's
1228# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
1229# you will indeed see the sunbeam illuminate the special spot at the
1230# expected time.
1231#
1232# However, that is only because of some special mirror contraption that had
1233# to be employed, since due to daylight savings time, the true solar time of
1234# the remembrance moment occurs one hour later (or earlier?). Perhaps
1235# someone with more information on this jury-rig can tell us more.

1541# The local time for general purposes in the Islands shall be

1543# as Pitcairn Standard Time.
1544#
1545# ... I have also seen Pitcairn listed as UTC minus 9 hours in several

1577# How Tonga became `The Land where Time Begins'
1578# </a>:
1579
1580# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
1581# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
1582# standard time in 1940s, Tonga had the choice of subtracting from its
1583# local time to come on the same standard time as New Zealand or of
1584# advancing its time to maintain the differential of 13 degrees
1585# (approximately 50 minutes ahead of New Zealand time).
1586#
1587# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1588# Tungi, preferred to ensure Tonga's title as the land where time
1589# begins, the Legislative Assembly approved the latter change.
1590#
1591# But some of the older, more conservative members from the outer
1592# islands objected. "If at midnight on Dec. 31, we move ahead 40
1593# minutes, as your Royal Highness wishes, what becomes of the 40
1594# minutes we have lost?"
1595#
1596# The Crown Prince, presented an unanswerable argument: "Remember that
1597# on the World Day of Prayer, you would be the first people on Earth
1598# to say your prayers in the morning."

1678# The International Date Line
1679
1680# From Gwillim Law (2000-01-03):
1681#
1682# The International Date Line is not defined by any international standard,
1683# convention, or treaty. Mapmakers are free to draw it as they please.
1684# Reputable mapmakers will simply ensure that every point of land appears on
1685# the correct side of the IDL, according to the date legally observed there.
1686#
1687# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1688# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1689# to the east side of the Phoenix and Line Islands), I suppose that most
1690# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
1691# has a rather arbitrary nature. The straight-line boundaries between Pacific
1692# island nations that are shown on many maps are based on an international
e1e23b59 1693# convention, but are not legally binding national borders.... The date is
984263bc
MD
1694# governed by the IDL; therefore, even on the high seas, there may be some
1695# places as late as fourteen hours later than UTC. And, since the IDL is not
1696# an international standard, there are some places on the high seas where the
1697# correct date is ambiguous.

1699# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
1700# Before 1920, all ships kept local apparent time on the high seas by setting
1701# their clocks at night or at the morning sight so that, given the ship's
1702# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
1703# meridian (12 o'clock = local apparent noon). During 1917, at the
1704# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
1705# ships, both military and civilian, should adopt hourly standard time zones
1706# on the high seas. Whenever a ship was within the territorial waters of any
1707# nation it would use that nation's standard time. The captain was permitted
1708# to change his ship's clocks at a time of his choice following his ship's
1709# entry into another zone time--he often chose midnight. These zones were
1710# adopted by all major fleets between 1920 and 1925 but not by many
1711# independent merchant ships until World War II.
