53# From Alex Livingston (1996-11-01):
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.

893
894# From John Mackin (1991-03-06):
895# We in Australia have _never_ referred to DST as `daylight' time.
896# It is called `summer' time.  Now by a happy coincidence, `summer'
897# and `standard' happen to start with the same letter; hence, the
898# abbreviation does _not_ change...
899# The legislation does not actually define abbreviations, at least
900# in this State, but the abbreviation is just commonly taken to be the
901# initials of the phrase, and the legislation here uniformly uses
902# the phrase `summer time' and does not use the phrase `daylight
903# time'.
904# Announcers on the Commonwealth radio network, the ABC (for Australian
905# Broadcasting Commission), use the phrases `Eastern Standard Time'
906# or `Eastern Summer Time'.  (Note, though, that as I say in the
907# current australasia file, there is really no such thing.)  Announcers
908# on its overseas service, Radio Australia, use the same phrases
909# prefixed by the word `Australian' when referring to local times;
910# time announcements on that service, naturally enough, are made in UTC.
911
912# From Arthur David Olson (1992-03-08):

915#	WST	for any place operating at a GMTOFF of 8:00
916#	EST	for any place operating at a GMTOFF of 10:00
917
918# From Chuck Soper (2006-06-01):
919# I recently found this Australian government web page on time zones:
920# <http://www.australia.gov.au/about-australia-13time>
921# And this government web page lists time zone names and abbreviations:
922# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml>
923
924# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
925# versus "AEST" etc.:
926#
927# I see the following points of dispute:
928#
929# * How important are unique time zone abbreviations?
930#
931#   Here I tend to agree with the point (most recently made by Chris
932#   Newman) that unique abbreviations should not be essential for proper
933#   operation of software.  We have other instances of ambiguity
934#   (e.g. "IST" denoting both "Israel Standard Time" and "Indian
935#   Standard Time"), and they are not likely to go away any time soon.
936#   In the old days, some software mistakenly relied on unique
937#   abbreviations, but this is becoming less true with time, and I don't
938#   think it's that important to cater to such software these days.
939#
940#   On the other hand, there is another motivation for unambiguous
941#   abbreviations: it cuts down on human confusion.  This is
942#   particularly true for Australia, where "EST" can mean one thing for
943#   time T and a different thing for time T plus 1 second.
944#
945# * Does the relevant legislation indicate which abbreviations should be used?
946#
947#   Here I tend to think that things are a mess, just as they are in
948#   many other countries.  We Americans are currently disagreeing about
949#   which abbreviation to use for the newly legislated Chamorro Standard
950#   Time, for example.
951#
952#   Personally, I would prefer to use common practice; I would like to
953#   refer to legislation only for examples of common practice, or as a
954#   tiebreaker.
955#
956# * Do Australians more often use "Eastern Daylight Time" or "Eastern
957#   Summer Time"?  Do they typically prefix the time zone names with
958#   the word "Australian"?
959#
960#   My own impression is that both "Daylight Time" and "Summer Time" are
961#   common and are widely understood, but that "Summer Time" is more
962#   popular; and that the leading "A" is also common but is omitted more
963#   often than not.  I just used AltaVista advanced search and got the
964#   following count of page hits:
965#
966#     1,103 "Eastern Summer Time" AND domain:au
967#       971 "Australian Eastern Summer Time" AND domain:au
968#       613 "Eastern Daylight Time" AND domain:au
969#       127 "Australian Eastern Daylight Time" AND domain:au
970#
971#   Here "Summer" seems quite a bit more popular than "Daylight",
972#   particularly when we know the time zone is Australian and not US,
973#   say.  The "Australian" prefix seems to be popular for Eastern Summer
974#   Time, but unpopular for Eastern Daylight Time.
975#
976#   For abbreviations, tools like AltaVista are less useful because of
977#   ambiguity.  Many hits are not really time zones, unfortunately, and
978#   many hits denote US time zones and not Australian ones.  But here
979#   are the hit counts anyway:
980#
981#     161,304 "EST" and domain:au
982#      25,156 "EDT" and domain:au
983#      18,263 "AEST" and domain:au
984#      10,416 "AEDT" and domain:au
985#
986#      14,538 "CST" and domain:au
987#       5,728 "CDT" and domain:au
988#         176 "ACST" and domain:au
989#          29 "ACDT" and domain:au
990#
991#       7,539 "WST" and domain:au
992#          68 "AWST" and domain:au
993#
994#   This data suggest that Australians tend to omit the "A" prefix in
995#   practice.  The situation for "ST" versus "DT" is less clear, given
996#   the ambiguities involved.
997#
998# * How do Australians feel about the abbreviations in the tz database?
999#
1000#   If you just count Australians on this list, I count 2 in favor and 3
1001#   against.  One of the "against" votes (David Keegel) counseled delay,
1002#   saying that both AEST/AEDT and EST/EST are widely used and
1003#   understood in Australia.

1005# From Paul Eggert (1995-12-19):

1142# From Rives McDow (2002-04-09):
1143# The most interesting region I have found consists of three towns on the
1144# southern coast....  South Australia observes daylight saving time; Western
1145# Australia does not.  The two states are one and a half hours apart.  The
1146# residents decided to forget about this nonsense of changing the clock so
1147# much and set the local time 20 hours and 45 minutes from the
1148# international date line, or right in the middle of the time of South
1149# Australia and Western Australia....
1150#
1151# From Paul Eggert (2002-04-09):
1152# This is confirmed by the section entitled

1157# ... it was just on four years ago that I drove along the Eyre Highway,
1158# which passes through eastern Western Australia close to the southern
1159# coast of the continent.
1160#
1161# I paid particular attention to the time kept there. There can be no
1162# dispute that UTC+08:45 was considered "the time" from the border
1163# village just inside the border with South Australia to as far west
1164# as just east of Caiguna. There can also be no dispute that Eucla is
1165# the largest population centre in this zone....
1166#
1167# Now that Western Australia is observing daylight saving, the
1168# question arose whether this part of the state would follow suit. I
1169# just called the border village and confirmed that indeed they have,
1170# meaning that they are now observing UTC+09:45.
1171#
1172# (2006-12-09):
1173# I personally doubt that either experimentation with daylight saving
1174# in WA or its introduction in SA had anything to do with the genesis
1175# of this time zone.  My hunch is that it's been around since well
1176# before 1975.  I remember seeing it noted on road maps decades ago.

1270# From Scott Harrington (2001-08-29):
1271# On KQED's "City Arts and Lectures" program last night I heard an
1272# interesting story about daylight savings time.  Dr. John Heilbron was
1273# discussing his book "The Sun in the Church: Cathedrals as Solar
1274# Observatories"[1], and in particular the Shrine of Remembrance[2] located
1275# in Melbourne, Australia.
1276#
1277# Apparently the shrine's main purpose is a beam of sunlight which
1278# illuminates a special spot on the floor at the 11th hour of the 11th day
1279# of the 11th month (Remembrance Day) every year in memory of Australia's
1280# fallen WWI soldiers.  And if you go there on Nov. 11, at 11am local time,
1281# you will indeed see the sunbeam illuminate the special spot at the
1282# expected time.
1283#
1284# However, that is only because of some special mirror contraption that had
1285# to be employed, since due to daylight savings time, the true solar time of
1286# the remembrance moment occurs one hour later (or earlier?).  Perhaps
1287# someone with more information on this jury-rig can tell us more.

1397# seeking the community's views on various options for summer time
1398# arrangements on the Island, e.g. advance clocks by 1 full hour
1399# instead of only 30 minutes.  [Dependent] on the wishes of residents

1405# Lord Howe Island advances clocks by 30 minutes during DST in NSW and retards

1407# introduced in NSW, the "changeover" time on the Island has been 02:00 as

1628# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
1629# How Tonga became `The Land where Time Begins'
1630# </a>:
1631
1632# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
1633# 12 hours and 20 minutes ahead of GMT.  When New Zealand adjusted its
1634# standard time in 1940s, Tonga had the choice of subtracting from its
1635# local time to come on the same standard time as New Zealand or of
1636# advancing its time to maintain the differential of 13 degrees
1637# (approximately 50 minutes ahead of New Zealand time).
1638#
1639# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1640# Tungi, preferred to ensure Tonga's title as the land where time
1641# begins, the Legislative Assembly approved the latter change.
1642#
1643# But some of the older, more conservative members from the outer
1644# islands objected. "If at midnight on Dec. 31, we move ahead 40
1645# minutes, as your Royal Highness wishes, what becomes of the 40
1646# minutes we have lost?"
1647#
1648# The Crown Prince, presented an unanswerable argument: "Remember that
1649# on the World Day of Prayer, you would be the first people on Earth
1650# to say your prayers in the morning."
1651

1730# The International Date Line
1731
1732# From Gwillim Law (2000-01-03):
1733#
1734# The International Date Line is not defined by any international standard,
1735# convention, or treaty.  Mapmakers are free to draw it as they please.
1736# Reputable mapmakers will simply ensure that every point of land appears on
1737# the correct side of the IDL, according to the date legally observed there.
1738#
1739# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1740# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1741# to the east side of the Phoenix and Line Islands), I suppose that most
1742# mapmakers redrew the IDL following the boundary of Kiribati.  Even that line
1743# has a rather arbitrary nature.  The straight-line boundaries between Pacific
1744# island nations that are shown on many maps are based on an international
1745# convention, but are not legally binding national borders.... The date is
1746# governed by the IDL; therefore, even on the high seas, there may be some
1747# places as late as fourteen hours later than UTC.  And, since the IDL is not
1748# an international standard, there are some places on the high seas where the
1749# correct date is ambiguous.
1750
1751# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
1752# Before 1920, all ships kept local apparent time on the high seas by setting
1753# their clocks at night or at the morning sight so that, given the ship's
1754# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
1755# meridian (12 o'clock = local apparent noon).  During 1917, at the
1756# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
1757# ships, both military and civilian, should adopt hourly standard time zones
1758# on the high seas.  Whenever a ship was within the territorial waters of any
1759# nation it would use that nation's standard time.  The captain was permitted
1760# to change his ship's clocks at a time of his choice following his ship's
1761# entry into another zone time--he often chose midnight.  These zones were
1762# adopted by all major fleets between 1920 and 1925 but not by many
1763# independent merchant ships until World War II.
