2458787Sru# Go with Whitman and the Australian National Standards Commission, which
2558787Sru# says W Australia didn't use DST in 1943/1944.  Ignore Whitman's claim that
2658787Sru# 1944/1945 was just like 1943/1944.

5620094Swollman# of Queensland chose to keep observing daylight-saving time even after
5720094Swollman# Queensland ceased to.

5920094Swollman# From Paul Eggert (1996-11-22):
6020094Swollman# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
6120094Swollman# Hamilton) observed DST for two years after the rest of Queensland stopped.
6220094Swollman# Hamilton is the largest, but there is also a Hamilton in Victoria,
6320094Swollman# so use Lindeman.

68519878Swollman# From John Mackin (1991-03-06):
6862742Swollman# We in Australia have _never_ referred to DST as `daylight' time.
6872742Swollman# It is called `summer' time.  Now by a happy coincidence, `summer'
6882742Swollman# and `standard' happen to start with the same letter; hence, the
6892742Swollman# abbreviation does _not_ change...
6902742Swollman# The legislation does not actually define abbreviations, at least
6912742Swollman# in this State, but the abbreviation is just commonly taken to be the
6922742Swollman# initials of the phrase, and the legislation here uniformly uses
6932742Swollman# the phrase `summer time' and does not use the phrase `daylight
6942742Swollman# time'.
6952742Swollman# Announcers on the Commonwealth radio network, the ABC (for Australian
6962742Swollman# Broadcasting Commission), use the phrases `Eastern Standard Time'
6972742Swollman# or `Eastern Summer Time'.  (Note, though, that as I say in the
6982742Swollman# current australasia file, there is really no such thing.)  Announcers
6992742Swollman# on its overseas service, Radio Australia, use the same phrases
7002742Swollman# prefixed by the word `Australian' when referring to local times;
7012742Swollman# time announcements on that service, naturally enough, are made in UTC.

710163302Sru# I recently found this Australian government web page on time zones:

712163302Sru# And this government web page lists time zone names and abbreviations:

714163302Sru
71586222Swollman# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
71686222Swollman# versus "AEST" etc.:
71786222Swollman#
71886222Swollman# I see the following points of dispute:
71986222Swollman#
72086222Swollman# * How important are unique time zone abbreviations?
72186222Swollman#
72286222Swollman#   Here I tend to agree with the point (most recently made by Chris
72386222Swollman#   Newman) that unique abbreviations should not be essential for proper
72486222Swollman#   operation of software.  We have other instances of ambiguity
72586222Swollman#   (e.g. "IST" denoting both "Israel Standard Time" and "Indian
72686222Swollman#   Standard Time"), and they are not likely to go away any time soon.
72786222Swollman#   In the old days, some software mistakenly relied on unique
72886222Swollman#   abbreviations, but this is becoming less true with time, and I don't
72986222Swollman#   think it's that important to cater to such software these days.
73086222Swollman#
73186222Swollman#   On the other hand, there is another motivation for unambiguous
73286222Swollman#   abbreviations: it cuts down on human confusion.  This is
73386222Swollman#   particularly true for Australia, where "EST" can mean one thing for
73486222Swollman#   time T and a different thing for time T plus 1 second.
73586222Swollman#
73686222Swollman# * Does the relevant legislation indicate which abbreviations should be used?
73786222Swollman#
73886222Swollman#   Here I tend to think that things are a mess, just as they are in
73986222Swollman#   many other countries.  We Americans are currently disagreeing about
74086222Swollman#   which abbreviation to use for the newly legislated Chamorro Standard
74186222Swollman#   Time, for example.
74286222Swollman#
74386222Swollman#   Personally, I would prefer to use common practice; I would like to
74486222Swollman#   refer to legislation only for examples of common practice, or as a
74586222Swollman#   tiebreaker.
74686222Swollman#
74786222Swollman# * Do Australians more often use "Eastern Daylight Time" or "Eastern
74886222Swollman#   Summer Time"?  Do they typically prefix the time zone names with
74986222Swollman#   the word "Australian"?
75086222Swollman#
75186222Swollman#   My own impression is that both "Daylight Time" and "Summer Time" are
75286222Swollman#   common and are widely understood, but that "Summer Time" is more
75386222Swollman#   popular; and that the leading "A" is also common but is omitted more
75486222Swollman#   often than not.  I just used AltaVista advanced search and got the
75586222Swollman#   following count of page hits:
75686222Swollman#
75786222Swollman#     1,103 "Eastern Summer Time" AND domain:au
75886222Swollman#       971 "Australian Eastern Summer Time" AND domain:au
75986222Swollman#       613 "Eastern Daylight Time" AND domain:au
76086222Swollman#       127 "Australian Eastern Daylight Time" AND domain:au
76186222Swollman#
76286222Swollman#   Here "Summer" seems quite a bit more popular than "Daylight",
76386222Swollman#   particularly when we know the time zone is Australian and not US,
76486222Swollman#   say.  The "Australian" prefix seems to be popular for Eastern Summer
76586222Swollman#   Time, but unpopular for Eastern Daylight Time.
76686222Swollman#
76786222Swollman#   For abbreviations, tools like AltaVista are less useful because of
76886222Swollman#   ambiguity.  Many hits are not really time zones, unfortunately, and
76986222Swollman#   many hits denote US time zones and not Australian ones.  But here
77086222Swollman#   are the hit counts anyway:
77186222Swollman#
77286222Swollman#     161,304 "EST" and domain:au
77386222Swollman#      25,156 "EDT" and domain:au
77486222Swollman#      18,263 "AEST" and domain:au
77586222Swollman#      10,416 "AEDT" and domain:au
77686222Swollman#
77786222Swollman#      14,538 "CST" and domain:au
77886222Swollman#       5,728 "CDT" and domain:au
77986222Swollman#         176 "ACST" and domain:au
78086222Swollman#          29 "ACDT" and domain:au
78186222Swollman#
78286222Swollman#       7,539 "WST" and domain:au
78386222Swollman#          68 "AWST" and domain:au
78486222Swollman#
78586222Swollman#   This data suggest that Australians tend to omit the "A" prefix in
78686222Swollman#   practice.  The situation for "ST" versus "DT" is less clear, given
78786222Swollman#   the ambiguities involved.
78886222Swollman#
78986222Swollman# * How do Australians feel about the abbreviations in the tz database?
79086222Swollman#
79186222Swollman#   If you just count Australians on this list, I count 2 in favor and 3
79286222Swollman#   against.  One of the "against" votes (David Keegel) counseled delay,
79386222Swollman#   saying that both AEST/AEDT and EST/EST are widely used and
79486222Swollman#   understood in Australia.
79586222Swollman
79614343Swollman# From Paul Eggert (1995-12-19):
797158421Swollman# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ.
798149514Swollman# Mark Prior writes that his newspaper
7999908Swollman# reports that NSW's fall 1995 change will occur at 2:00,
8009908Swollman# but Robert Elz says it's been 3:00 in Victoria since 1970
8019908Swollman# and perhaps the newspaper's `2:00' is referring to standard time.
80214343Swollman# For now we'll continue to assume 2:00s for changes since 1960.

950169811Swollman# coast of the continent.
951105196Swollman#
952169811Swollman# I paid particular attention to the time kept there. There can be no
953169811Swollman# dispute that UTC+08:45 was considered "the time" from the border
954169811Swollman# village just inside the border with South Australia to as far west

962169811Swollman#
963169811Swollman# (2006-12-09):
964169811Swollman# I personally doubt that either experimentation with daylight saving

106186222Swollman# From Scott Harrington (2001-08-29):
106286222Swollman# On KQED's "City Arts and Lectures" program last night I heard an
106386222Swollman# interesting story about daylight savings time.  Dr. John Heilbron was
106486222Swollman# discussing his book "The Sun in the Church: Cathedrals as Solar
106586222Swollman# Observatories"[1], and in particular the Shrine of Remembrance[2] located
106686222Swollman# in Melbourne, Australia.
106786222Swollman#
106886222Swollman# Apparently the shrine's main purpose is a beam of sunlight which
106986222Swollman# illuminates a special spot on the floor at the 11th hour of the 11th day
107086222Swollman# of the 11th month (Remembrance Day) every year in memory of Australia's
107186222Swollman# fallen WWI soldiers.  And if you go there on Nov. 11, at 11am local time,
107286222Swollman# you will indeed see the sunbeam illuminate the special spot at the
107386222Swollman# expected time.
107486222Swollman#
107586222Swollman# However, that is only because of some special mirror contraption that had
107686222Swollman# to be employed, since due to daylight savings time, the true solar time of
107786222Swollman# the remembrance moment occurs one hour later (or earlier?).  Perhaps

141958787Sru# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
142058787Sru# How Tonga became `The Land where Time Begins'
142158787Sru# </a>:
142258787Sru
142358787Sru# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
142458787Sru# 12 hours and 20 minutes ahead of GMT.  When New Zealand adjusted its
142558787Sru# standard time in 1940s, Tonga had the choice of subtracting from its
142658787Sru# local time to come on the same standard time as New Zealand or of
142758787Sru# advancing its time to maintain the differential of 13 degrees
142858787Sru# (approximately 50 minutes ahead of New Zealand time).
142958787Sru#
143058787Sru# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
143158787Sru# Tungi, preferred to ensure Tonga's title as the land where time
143258787Sru# begins, the Legislative Assembly approved the latter change.
143358787Sru#
143458787Sru# But some of the older, more conservative members from the outer
143558787Sru# islands objected. "If at midnight on Dec. 31, we move ahead 40
143658787Sru# minutes, as your Royal Highness wishes, what becomes of the 40
143758787Sru# minutes we have lost?"
143858787Sru#
143958787Sru# The Crown Prince, presented an unanswerable argument: "Remember that
144058787Sru# on the World Day of Prayer, you would be the first people on Earth
144158787Sru# to say your prayers in the morning."

152358787Sru# From Gwillim Law (2000-01-03):
152475267Swollman#
152558787Sru# The International Date Line is not defined by any international standard,
152658787Sru# convention, or treaty.  Mapmakers are free to draw it as they please.
152758787Sru# Reputable mapmakers will simply ensure that every point of land appears on
152858787Sru# the correct side of the IDL, according to the date legally observed there.
152958787Sru#
153058787Sru# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
153158787Sru# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
153258787Sru# to the east side of the Phoenix and Line Islands), I suppose that most
153358787Sru# mapmakers redrew the IDL following the boundary of Kiribati.  Even that line
153458787Sru# has a rather arbitrary nature.  The straight-line boundaries between Pacific
153558787Sru# island nations that are shown on many maps are based on an international
1536153670Swollman# convention, but are not legally binding national borders.... The date is
153758787Sru# governed by the IDL; therefore, even on the high seas, there may be some
153858787Sru# places as late as fourteen hours later than UTC.  And, since the IDL is not
153958787Sru# an international standard, there are some places on the high seas where the
154058787Sru# correct date is ambiguous.
1541149514Swollman
1542153670Swollman# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
1543153670Swollman# Before 1920, all ships kept local apparent time on the high seas by setting
1544153670Swollman# their clocks at night or at the morning sight so that, given the ship's
1545153670Swollman# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
1546153670Swollman# meridian (12 o'clock = local apparent noon).  During 1917, at the
1547153670Swollman# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
1548153670Swollman# ships, both military and civilian, should adopt hourly standard time zones
1549153670Swollman# on the high seas.  Whenever a ship was within the territorial waters of any
1550153670Swollman# nation it would use that nation's standard time.  The captain was permitted
1551153670Swollman# to change his ship's clocks at a time of his choice following his ship's
1552153670Swollman# entry into another zone time--he often chose midnight.  These zones were
1553153670Swollman# adopted by all major fleets between 1920 and 1925 but not by many
1554153670Swollman# independent merchant ships until World War II.
