77# Queensland ceased to.
78#
79# From Paul Eggert (1996-11-22):
80# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
81# Hamilton) observed DST for two years after the rest of Queensland stopped.
82# Hamilton is the largest, but there is also a Hamilton in Victoria,
83# so use Lindeman.

619
620# From John Mackin (1991-03-06):
621# We in Australia have _never_ referred to DST as `daylight' time.
622# It is called `summer' time. Now by a happy coincidence, `summer'
623# and `standard' happen to start with the same letter; hence, the
624# abbreviation does _not_ change...
625# The legislation does not actually define abbreviations, at least
626# in this State, but the abbreviation is just commonly taken to be the
627# initials of the phrase, and the legislation here uniformly uses
628# the phrase `summer time' and does not use the phrase `daylight
629# time'.
630# Announcers on the Commonwealth radio network, the ABC (for Australian
631# Broadcasting Commission), use the phrases `Eastern Standard Time'
632# or `Eastern Summer Time'. (Note, though, that as I say in the
633# current australasia file, there is really no such thing.) Announcers
634# on its overseas service, Radio Australia, use the same phrases
635# prefixed by the word `Australian' when referring to local times;
636# time announcements on that service, naturally enough, are made in UTC.
637
638# From Arthur David Olson (1992-03-08):
639# Given the above, what's chosen for year-round use is:
640# CST for any place operating at a GMTOFF of 9:30
641# WST for any place operating at a GMTOFF of 8:00
642# EST for any place operating at a GMTOFF of 10:00
643
644# From Chuck Soper (2006-06-01):
645# I recently found this Australian government web page on time zones:
646# <http://www.australia.gov.au/about-australia-13time>
647# And this government web page lists time zone names and abbreviations:
648# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml>
649
650# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
651# versus "AEST" etc.:
652#
653# I see the following points of dispute:
654#
655# * How important are unique time zone abbreviations?
656#
657# Here I tend to agree with the point (most recently made by Chris
658# Newman) that unique abbreviations should not be essential for proper
659# operation of software. We have other instances of ambiguity
660# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
661# Standard Time"), and they are not likely to go away any time soon.
662# In the old days, some software mistakenly relied on unique
663# abbreviations, but this is becoming less true with time, and I don't
664# think it's that important to cater to such software these days.
665#
666# On the other hand, there is another motivation for unambiguous
667# abbreviations: it cuts down on human confusion. This is
668# particularly true for Australia, where "EST" can mean one thing for
669# time T and a different thing for time T plus 1 second.
670#
671# * Does the relevant legislation indicate which abbreviations should be used?
672#
673# Here I tend to think that things are a mess, just as they are in
674# many other countries. We Americans are currently disagreeing about
675# which abbreviation to use for the newly legislated Chamorro Standard
676# Time, for example.
677#
678# Personally, I would prefer to use common practice; I would like to
679# refer to legislation only for examples of common practice, or as a
680# tiebreaker.
681#
682# * Do Australians more often use "Eastern Daylight Time" or "Eastern
683# Summer Time"? Do they typically prefix the time zone names with
684# the word "Australian"?
685#
686# My own impression is that both "Daylight Time" and "Summer Time" are
687# common and are widely understood, but that "Summer Time" is more
688# popular; and that the leading "A" is also common but is omitted more
689# often than not. I just used AltaVista advanced search and got the
690# following count of page hits:
691#
692# 1,103 "Eastern Summer Time" AND domain:au
693# 971 "Australian Eastern Summer Time" AND domain:au
694# 613 "Eastern Daylight Time" AND domain:au
695# 127 "Australian Eastern Daylight Time" AND domain:au
696#
697# Here "Summer" seems quite a bit more popular than "Daylight",
698# particularly when we know the time zone is Australian and not US,
699# say. The "Australian" prefix seems to be popular for Eastern Summer
700# Time, but unpopular for Eastern Daylight Time.
701#
702# For abbreviations, tools like AltaVista are less useful because of
703# ambiguity. Many hits are not really time zones, unfortunately, and
704# many hits denote US time zones and not Australian ones. But here
705# are the hit counts anyway:
706#
707# 161,304 "EST" and domain:au
708# 25,156 "EDT" and domain:au
709# 18,263 "AEST" and domain:au
710# 10,416 "AEDT" and domain:au
711#
712# 14,538 "CST" and domain:au
713# 5,728 "CDT" and domain:au
714# 176 "ACST" and domain:au
715# 29 "ACDT" and domain:au
716#
717# 7,539 "WST" and domain:au
718# 68 "AWST" and domain:au
719#
720# This data suggest that Australians tend to omit the "A" prefix in
721# practice. The situation for "ST" versus "DT" is less clear, given
722# the ambiguities involved.
723#
724# * How do Australians feel about the abbreviations in the tz database?
725#
726# If you just count Australians on this list, I count 2 in favor and 3
727# against. One of the "against" votes (David Keegel) counseled delay,
728# saying that both AEST/AEDT and EST/EST are widely used and
729# understood in Australia.
730
731# From Paul Eggert (1995-12-19):
732# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ.
733# Mark Prior writes that his newspaper
734# reports that NSW's fall 1995 change will occur at 2:00,
735# but Robert Elz says it's been 3:00 in Victoria since 1970
736# and perhaps the newspaper's `2:00' is referring to standard time.
737# For now we'll continue to assume 2:00s for changes since 1960.

869# The most interesting region I have found consists of three towns on the

871# Australia does not. The two states are one and a half hours apart. The
872# residents decided to forget about this nonsense of changing the clock so
873# much and set the local time 20 hours and 45 minutes from the
874# international date line, or right in the middle of the time of South
875# Australia and Western Australia....

884# which passes through eastern Western Australia close to the southern
885# coast of the continent.
886#
887# I paid particular attention to the time kept there. There can be no
888# dispute that UTC+08:45 was considered "the time" from the border
889# village just inside the border with South Australia to as far west
890# as just east of Caiguna. There can also be no dispute that Eucla is
891# the largest population centre in this zone....
892#
893# Now that Western Australia is observing daylight saving, the
894# question arose whether this part of the state would follow suit. I
895# just called the border village and confirmed that indeed they have,

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

999# discussing his book "The Sun in the Church: Cathedrals as Solar
1000# Observatories"[1], and in particular the Shrine of Remembrance[2] located
1001# in Melbourne, Australia.
1002#
1003# Apparently the shrine's main purpose is a beam of sunlight which
1004# illuminates a special spot on the floor at the 11th hour of the 11th day
1005# of the 11th month (Remembrance Day) every year in memory of Australia's
1006# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
1007# you will indeed see the sunbeam illuminate the special spot at the
1008# expected time.
1009#
1010# However, that is only because of some special mirror contraption that had
1011# to be employed, since due to daylight savings time, the true solar time of
1012# the remembrance moment occurs one hour later (or earlier?). Perhaps
1013# someone with more information on this jury-rig can tell us more.

1333# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
1334# How Tonga became `The Land where Time Begins'
1335# </a>:
1336
1337# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
1338# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
1339# standard time in 1940s, Tonga had the choice of subtracting from its
1340# local time to come on the same standard time as New Zealand or of
1341# advancing its time to maintain the differential of 13 degrees
1342# (approximately 50 minutes ahead of New Zealand time).
1343#
1344# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1345# Tungi, preferred to ensure Tonga's title as the land where time
1346# begins, the Legislative Assembly approved the latter change.
1347#
1348# But some of the older, more conservative members from the outer
1349# islands objected. "If at midnight on Dec. 31, we move ahead 40
1350# minutes, as your Royal Highness wishes, what becomes of the 40
1351# minutes we have lost?"
1352#
1353# The Crown Prince, presented an unanswerable argument: "Remember that
1354# on the World Day of Prayer, you would be the first people on Earth
1355# to say your prayers in the morning."
1356
1357# From Paul Eggert (2006-03-22):

1435# The International Date Line
1436
1437# From Gwillim Law (2000-01-03):
1438#
1439# The International Date Line is not defined by any international standard,
1440# convention, or treaty. Mapmakers are free to draw it as they please.
1441# Reputable mapmakers will simply ensure that every point of land appears on
1442# the correct side of the IDL, according to the date legally observed there.
1443#
1444# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1445# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1446# to the east side of the Phoenix and Line Islands), I suppose that most
1447# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
1448# has a rather arbitrary nature. The straight-line boundaries between Pacific
1449# island nations that are shown on many maps are based on an international
1450# convention, but are not legally binding national borders.... The date is
1451# governed by the IDL; therefore, even on the high seas, there may be some
1452# places as late as fourteen hours later than UTC. And, since the IDL is not
1453# an international standard, there are some places on the high seas where the
1454# correct date is ambiguous.
1455
1456# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
1457# Before 1920, all ships kept local apparent time on the high seas by setting
1458# their clocks at night or at the morning sight so that, given the ship's
1459# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
1460# meridian (12 o'clock = local apparent noon). During 1917, at the
1461# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
1462# ships, both military and civilian, should adopt hourly standard time zones
1463# on the high seas. Whenever a ship was within the territorial waters of any
1464# nation it would use that nation's standard time. The captain was permitted
1465# to change his ship's clocks at a time of his choice following his ship's
1466# entry into another zone time--he often chose midnight. These zones were
1467# adopted by all major fleets between 1920 and 1925 but not by many
1468# independent merchant ships until World War II.
