77# I have heard or read more than once that some resort islands off the coast
78# of Queensland chose to keep observing daylight-saving time even after
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,
85# so use Lindeman.

653# Gwillim Law writes that a good source

704
705# From John Mackin (1991-03-06):
706# We in Australia have _never_ referred to DST as `daylight' time.
707# It is called `summer' time. Now by a happy coincidence, `summer'
708# and `standard' happen to start with the same letter; hence, the
709# abbreviation does _not_ change...
710# The legislation does not actually define abbreviations, at least
711# in this State, but the abbreviation is just commonly taken to be the
712# initials of the phrase, and the legislation here uniformly uses
713# the phrase `summer time' and does not use the phrase `daylight
714# time'.
715# Announcers on the Commonwealth radio network, the ABC (for Australian
716# Broadcasting Commission), use the phrases `Eastern Standard Time'
717# or `Eastern Summer Time'. (Note, though, that as I say in the
718# current australasia file, there is really no such thing.) Announcers
719# on its overseas service, Radio Australia, use the same phrases
720# prefixed by the word `Australian' when referring to local times;
721# time announcements on that service, naturally enough, are made in UTC.
722
723# From Arthur David Olson (1992-03-08):
724# Given the above, what's chosen for year-round use is:

726# WST for any place operating at a GMTOFF of 8:00
727# EST for any place operating at a GMTOFF of 10:00
728
729# From Chuck Soper (2006-06-01):
730# I recently found this Australian government web page on time zones:
731# <http://www.australia.gov.au/about-australia-13time>
732# And this government web page lists time zone names and abbreviations:
733# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml>
734
735# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
736# versus "AEST" etc.:
737#
738# I see the following points of dispute:
739#
740# * How important are unique time zone abbreviations?
741#
742# Here I tend to agree with the point (most recently made by Chris
743# Newman) that unique abbreviations should not be essential for proper
744# operation of software. We have other instances of ambiguity
745# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
746# Standard Time"), and they are not likely to go away any time soon.
747# In the old days, some software mistakenly relied on unique
748# abbreviations, but this is becoming less true with time, and I don't
749# think it's that important to cater to such software these days.
750#
751# On the other hand, there is another motivation for unambiguous
752# abbreviations: it cuts down on human confusion. This is
753# particularly true for Australia, where "EST" can mean one thing for
754# time T and a different thing for time T plus 1 second.
755#
756# * Does the relevant legislation indicate which abbreviations should be used?
757#
758# Here I tend to think that things are a mess, just as they are in
759# many other countries. We Americans are currently disagreeing about
760# which abbreviation to use for the newly legislated Chamorro Standard
761# Time, for example.
762#
763# Personally, I would prefer to use common practice; I would like to
764# refer to legislation only for examples of common practice, or as a
765# tiebreaker.
766#
767# * Do Australians more often use "Eastern Daylight Time" or "Eastern
768# Summer Time"? Do they typically prefix the time zone names with
769# the word "Australian"?
770#
771# My own impression is that both "Daylight Time" and "Summer Time" are
772# common and are widely understood, but that "Summer Time" is more
773# popular; and that the leading "A" is also common but is omitted more
774# often than not. I just used AltaVista advanced search and got the
775# following count of page hits:
776#
777# 1,103 "Eastern Summer Time" AND domain:au
778# 971 "Australian Eastern Summer Time" AND domain:au
779# 613 "Eastern Daylight Time" AND domain:au
780# 127 "Australian Eastern Daylight Time" AND domain:au
781#
782# Here "Summer" seems quite a bit more popular than "Daylight",
783# particularly when we know the time zone is Australian and not US,
784# say. The "Australian" prefix seems to be popular for Eastern Summer
785# Time, but unpopular for Eastern Daylight Time.
786#
787# For abbreviations, tools like AltaVista are less useful because of
788# ambiguity. Many hits are not really time zones, unfortunately, and
789# many hits denote US time zones and not Australian ones. But here
790# are the hit counts anyway:
791#
792# 161,304 "EST" and domain:au
793# 25,156 "EDT" and domain:au

971#
972# I paid particular attention to the time kept there. There can be no
973# dispute that UTC+08:45 was considered "the time" from the border
974# village just inside the border with South Australia to as far west
975# as just east of Caiguna. There can also be no dispute that Eucla is
976# the largest population centre in this zone....
977#
978# Now that Western Australia is observing daylight saving, the
979# question arose whether this part of the state would follow suit. I
980# just called the border village and confirmed that indeed they have,

1082# On KQED's "City Arts and Lectures" program last night I heard an

1084# discussing his book "The Sun in the Church: Cathedrals as Solar
1085# Observatories"[1], and in particular the Shrine of Remembrance[2] located
1086# in Melbourne, Australia.
1087#
1088# Apparently the shrine's main purpose is a beam of sunlight which
1089# illuminates a special spot on the floor at the 11th hour of the 11th day
1090# of the 11th month (Remembrance Day) every year in memory of Australia's
1091# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
1092# you will indeed see the sunbeam illuminate the special spot at the
1093# expected time.
1094#
1095# However, that is only because of some special mirror contraption that had
1096# to be employed, since due to daylight savings time, the true solar time of
1097# the remembrance moment occurs one hour later (or earlier?). Perhaps
1098# someone with more information on this jury-rig can tell us more.

1218# introduced in NSW, the "changeover" time on the Island has been 02:00 as

1440# How Tonga became `The Land where Time Begins'
1441# </a>:
1442
1443# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
1444# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
1445# standard time in 1940s, Tonga had the choice of subtracting from its
1446# local time to come on the same standard time as New Zealand or of
1447# advancing its time to maintain the differential of 13 degrees
1448# (approximately 50 minutes ahead of New Zealand time).
1449#
1450# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1451# Tungi, preferred to ensure Tonga's title as the land where time
1452# begins, the Legislative Assembly approved the latter change.
1453#
1454# But some of the older, more conservative members from the outer
1455# islands objected. "If at midnight on Dec. 31, we move ahead 40
1456# minutes, as your Royal Highness wishes, what becomes of the 40
1457# minutes we have lost?"
1458#
1459# The Crown Prince, presented an unanswerable argument: "Remember that
1460# on the World Day of Prayer, you would be the first people on Earth
1461# to say your prayers in the morning."
1462

1541# The International Date Line
1542
1543# From Gwillim Law (2000-01-03):
1544#
1545# The International Date Line is not defined by any international standard,
1546# convention, or treaty. Mapmakers are free to draw it as they please.
1547# Reputable mapmakers will simply ensure that every point of land appears on
1548# the correct side of the IDL, according to the date legally observed there.
1549#
1550# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1551# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1552# to the east side of the Phoenix and Line Islands), I suppose that most
1553# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
1554# has a rather arbitrary nature. The straight-line boundaries between Pacific
1555# island nations that are shown on many maps are based on an international
1556# convention, but are not legally binding national borders.... The date is
1557# governed by the IDL; therefore, even on the high seas, there may be some
1558# places as late as fourteen hours later than UTC. And, since the IDL is not
1559# an international standard, there are some places on the high seas where the
1560# correct date is ambiguous.
1561
1562# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
1563# Before 1920, all ships kept local apparent time on the high seas by setting
1564# their clocks at night or at the morning sight so that, given the ship's
1565# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
1566# meridian (12 o'clock = local apparent noon). During 1917, at the
1567# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
1568# ships, both military and civilian, should adopt hourly standard time zones
1569# on the high seas. Whenever a ship was within the territorial waters of any
1570# nation it would use that nation's standard time. The captain was permitted
1571# to change his ship's clocks at a time of his choice following his ship's
1572# entry into another zone time--he often chose midnight. These zones were
1573# adopted by all major fleets between 1920 and 1925 but not by many
1574# independent merchant ships until World War II.
