79# Queensland ceased to.
80#
81# From Paul Eggert (1996-11-22):
82# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
83# Hamilton) observed DST for two years after the rest of Queensland stopped.
84# Hamilton is the largest, but there is also a Hamilton in Victoria,

801
802# From John Mackin (1991-03-06):
803# We in Australia have _never_ referred to DST as `daylight' time.
804# It is called `summer' time. Now by a happy coincidence, `summer'
805# and `standard' happen to start with the same letter; hence, the
806# abbreviation does _not_ change...
807# The legislation does not actually define abbreviations, at least
808# in this State, but the abbreviation is just commonly taken to be the
809# initials of the phrase, and the legislation here uniformly uses
810# the phrase `summer time' and does not use the phrase `daylight
811# time'.
812# Announcers on the Commonwealth radio network, the ABC (for Australian
813# Broadcasting Commission), use the phrases `Eastern Standard Time'
814# or `Eastern Summer Time'. (Note, though, that as I say in the
815# current australasia file, there is really no such thing.) Announcers
816# on its overseas service, Radio Australia, use the same phrases
817# prefixed by the word `Australian' when referring to local times;
818# time announcements on that service, naturally enough, are made in UTC.
819
820# From Arthur David Olson (1992-03-08):

824# EST for any place operating at a GMTOFF of 10:00
825
826# From Chuck Soper (2006-06-01):
827# I recently found this Australian government web page on time zones:
828# <http://www.australia.gov.au/about-australia-13time>
829# And this government web page lists time zone names and abbreviations:
830# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml>
831
832# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
833# versus "AEST" etc.:
834#
835# I see the following points of dispute:
836#
837# * How important are unique time zone abbreviations?
838#
839# Here I tend to agree with the point (most recently made by Chris
840# Newman) that unique abbreviations should not be essential for proper
841# operation of software. We have other instances of ambiguity
842# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
843# Standard Time"), and they are not likely to go away any time soon.
844# In the old days, some software mistakenly relied on unique
845# abbreviations, but this is becoming less true with time, and I don't
846# think it's that important to cater to such software these days.
847#
848# On the other hand, there is another motivation for unambiguous
849# abbreviations: it cuts down on human confusion. This is
850# particularly true for Australia, where "EST" can mean one thing for
851# time T and a different thing for time T plus 1 second.
852#
853# * Does the relevant legislation indicate which abbreviations should be used?
854#
855# Here I tend to think that things are a mess, just as they are in
856# many other countries. We Americans are currently disagreeing about
857# which abbreviation to use for the newly legislated Chamorro Standard
858# Time, for example.
859#
860# Personally, I would prefer to use common practice; I would like to
861# refer to legislation only for examples of common practice, or as a
862# tiebreaker.
863#
864# * Do Australians more often use "Eastern Daylight Time" or "Eastern
865# Summer Time"? Do they typically prefix the time zone names with
866# the word "Australian"?
867#
868# My own impression is that both "Daylight Time" and "Summer Time" are
869# common and are widely understood, but that "Summer Time" is more
870# popular; and that the leading "A" is also common but is omitted more
871# often than not. I just used AltaVista advanced search and got the
872# following count of page hits:
873#
874# 1,103 "Eastern Summer Time" AND domain:au
875# 971 "Australian Eastern Summer Time" AND domain:au
876# 613 "Eastern Daylight Time" AND domain:au
877# 127 "Australian Eastern Daylight Time" AND domain:au
878#
879# Here "Summer" seems quite a bit more popular than "Daylight",
880# particularly when we know the time zone is Australian and not US,
881# say. The "Australian" prefix seems to be popular for Eastern Summer
882# Time, but unpopular for Eastern Daylight Time.
883#
884# For abbreviations, tools like AltaVista are less useful because of
885# ambiguity. Many hits are not really time zones, unfortunately, and
886# many hits denote US time zones and not Australian ones. But here
887# are the hit counts anyway:
888#
889# 161,304 "EST" and domain:au
890# 25,156 "EDT" and domain:au
891# 18,263 "AEST" and domain:au
892# 10,416 "AEDT" and domain:au
893#
894# 14,538 "CST" and domain:au
895# 5,728 "CDT" and domain:au
896# 176 "ACST" and domain:au
897# 29 "ACDT" and domain:au
898#
899# 7,539 "WST" and domain:au
900# 68 "AWST" and domain:au
901#
902# This data suggest that Australians tend to omit the "A" prefix in
903# practice. The situation for "ST" versus "DT" is less clear, given
904# the ambiguities involved.
905#
906# * How do Australians feel about the abbreviations in the tz database?
907#
908# If you just count Australians on this list, I count 2 in favor and 3
909# against. One of the "against" votes (David Keegel) counseled delay,
910# saying that both AEST/AEDT and EST/EST are widely used and
911# understood in Australia.
912
913# From Paul Eggert (1995-12-19):
914# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ.
915# Mark Prior writes that his newspaper
916# reports that NSW's fall 1995 change will occur at 2:00,
917# but Robert Elz says it's been 3:00 in Victoria since 1970
918# and perhaps the newspaper's `2:00' is referring to standard time.
919# For now we'll continue to assume 2:00s for changes since 1960.

1050# From Rives McDow (2002-04-09):
1051# The most interesting region I have found consists of three towns on the
1052# southern coast.... South Australia observes daylight saving time; Western
1053# Australia does not. The two states are one and a half hours apart. The
1054# residents decided to forget about this nonsense of changing the clock so
1055# much and set the local time 20 hours and 45 minutes from the
1056# international date line, or right in the middle of the time of South
1057# Australia and Western Australia....
1058#
1059# From Paul Eggert (2002-04-09):
1060# This is confirmed by the section entitled
1061# "What's the deal with time zones???" in
1062# <http://www.earthsci.unimelb.edu.au/~awatkins/null.html>.
1063#
1064# From Alex Livingston (2006-12-07):
1065# ... it was just on four years ago that I drove along the Eyre Highway,
1066# which passes through eastern Western Australia close to the southern
1067# coast of the continent.
1068#
1069# I paid particular attention to the time kept there. There can be no
1070# dispute that UTC+08:45 was considered "the time" from the border
1071# village just inside the border with South Australia to as far west
1072# as just east of Caiguna. There can also be no dispute that Eucla is
1073# the largest population centre in this zone....
1074#
1075# Now that Western Australia is observing daylight saving, the
1076# question arose whether this part of the state would follow suit. I
1077# just called the border village and confirmed that indeed they have,
1078# meaning that they are now observing UTC+09:45.
1079#
1080# (2006-12-09):
1081# I personally doubt that either experimentation with daylight saving
1082# in WA or its introduction in SA had anything to do with the genesis

1178# From Scott Harrington (2001-08-29):
1179# On KQED's "City Arts and Lectures" program last night I heard an
1180# interesting story about daylight savings time. Dr. John Heilbron was
1181# discussing his book "The Sun in the Church: Cathedrals as Solar
1182# Observatories"[1], and in particular the Shrine of Remembrance[2] located
1183# in Melbourne, Australia.
1184#
1185# Apparently the shrine's main purpose is a beam of sunlight which
1186# illuminates a special spot on the floor at the 11th hour of the 11th day
1187# of the 11th month (Remembrance Day) every year in memory of Australia's
1188# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
1189# you will indeed see the sunbeam illuminate the special spot at the
1190# expected time.
1191#
1192# However, that is only because of some special mirror contraption that had
1193# to be employed, since due to daylight savings time, the true solar time of
1194# the remembrance moment occurs one hour later (or earlier?). Perhaps
1195# someone with more information on this jury-rig can tell us more.

1551# But some of the older, more conservative members from the outer
1552# islands objected. "If at midnight on Dec. 31, we move ahead 40
1553# minutes, as your Royal Highness wishes, what becomes of the 40
1554# minutes we have lost?"
1555#
1556# The Crown Prince, presented an unanswerable argument: "Remember that
1557# on the World Day of Prayer, you would be the first people on Earth
1558# to say your prayers in the morning."

1564# Tonga's director of tourism, who is also secretary of the National Millenium
1565# Committee, has a plan to get Tonga back in front.
1566# He has proposed a one-off move to tropical daylight saving for Tonga from
1567# October to March, which has won approval in principle from the Tongan
1568# Government.

1623#
1624# Saturday, the 14th [of October, 1950] -- ... The time was all the
1625# more confusing at that point, because we had crossed the
1626# International Date Line, thus getting two Sundays. Furthermore, we
1627# discovered that Wake Island had two hours of daylight saving time
1628# making calculation of time in Washington difficult if not almost
1629# impossible.

1638# The International Date Line
1639
1640# From Gwillim Law (2000-01-03):
1641#
1642# The International Date Line is not defined by any international standard,
1643# convention, or treaty. Mapmakers are free to draw it as they please.
1644# Reputable mapmakers will simply ensure that every point of land appears on
1645# the correct side of the IDL, according to the date legally observed there.
1646#
1647# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1648# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1649# to the east side of the Phoenix and Line Islands), I suppose that most
1650# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
1651# has a rather arbitrary nature. The straight-line boundaries between Pacific
1652# island nations that are shown on many maps are based on an international
1653# convention, but are not legally binding national borders.... The date is
1654# governed by the IDL; therefore, even on the high seas, there may be some
1655# places as late as fourteen hours later than UTC. And, since the IDL is not
1656# an international standard, there are some places on the high seas where the
1657# correct date is ambiguous.
1658
1659# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
1660# Before 1920, all ships kept local apparent time on the high seas by setting
1661# their clocks at night or at the morning sight so that, given the ship's
1662# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
1663# meridian (12 o'clock = local apparent noon). During 1917, at the
1664# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
1665# ships, both military and civilian, should adopt hourly standard time zones
1666# on the high seas. Whenever a ship was within the territorial waters of any
1667# nation it would use that nation's standard time. The captain was permitted
1668# to change his ship's clocks at a time of his choice following his ship's
1669# entry into another zone time--he often chose midnight. These zones were
1670# adopted by all major fleets between 1920 and 1925 but not by many
1671# independent merchant ships until World War II.

1676# The American Practical Navigator (2002)
1677# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187>
1678# talks only about the 180-degree meridian with respect to ships in
1679# international waters; it ignores the international date line.
