55# I have heard or read more than once that some resort islands off the coast
56# of Queensland chose to keep observing daylight-saving time even after
57# Queensland ceased to.
58#
59# From Paul Eggert (1996-11-22):
60# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
61# Hamilton) observed DST for two years after the rest of Queensland stopped.
62# Hamilton is the largest, but there is also a Hamilton in Victoria,
63# so use Lindeman.

766# From John Mackin (1991-03-06):
767# We in Australia have _never_ referred to DST as `daylight' time.
768# It is called `summer' time. Now by a happy coincidence, `summer'
769# and `standard' happen to start with the same letter; hence, the
770# abbreviation does _not_ change...
771# The legislation does not actually define abbreviations, at least
772# in this State, but the abbreviation is just commonly taken to be the
773# initials of the phrase, and the legislation here uniformly uses
774# the phrase `summer time' and does not use the phrase `daylight
775# time'.
776# Announcers on the Commonwealth radio network, the ABC (for Australian
777# Broadcasting Commission), use the phrases `Eastern Standard Time'
778# or `Eastern Summer Time'. (Note, though, that as I say in the
779# current australasia file, there is really no such thing.) Announcers
780# on its overseas service, Radio Australia, use the same phrases
781# prefixed by the word `Australian' when referring to local times;
782# time announcements on that service, naturally enough, are made in UTC.

984263bc
MD
796# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
797# versus "AEST" etc.:
798#
799# I see the following points of dispute:
800#
801# * How important are unique time zone abbreviations?
802#
803# Here I tend to agree with the point (most recently made by Chris
804# Newman) that unique abbreviations should not be essential for proper
805# operation of software. We have other instances of ambiguity
806# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
807# Standard Time"), and they are not likely to go away any time soon.
808# In the old days, some software mistakenly relied on unique
809# abbreviations, but this is becoming less true with time, and I don't
810# think it's that important to cater to such software these days.
811#
812# On the other hand, there is another motivation for unambiguous
813# abbreviations: it cuts down on human confusion. This is
814# particularly true for Australia, where "EST" can mean one thing for
815# time T and a different thing for time T plus 1 second.
816#
817# * Does the relevant legislation indicate which abbreviations should be used?
818#
819# Here I tend to think that things are a mess, just as they are in
820# many other countries. We Americans are currently disagreeing about
821# which abbreviation to use for the newly legislated Chamorro Standard
822# Time, for example.
823#
824# Personally, I would prefer to use common practice; I would like to
825# refer to legislation only for examples of common practice, or as a
826# tiebreaker.
827#
828# * Do Australians more often use "Eastern Daylight Time" or "Eastern
829# Summer Time"? Do they typically prefix the time zone names with
830# the word "Australian"?
831#
832# My own impression is that both "Daylight Time" and "Summer Time" are
833# common and are widely understood, but that "Summer Time" is more
834# popular; and that the leading "A" is also common but is omitted more
835# often than not. I just used AltaVista advanced search and got the
836# following count of page hits:
837#
838# 1,103 "Eastern Summer Time" AND domain:au
839# 971 "Australian Eastern Summer Time" AND domain:au
840# 613 "Eastern Daylight Time" AND domain:au
841# 127 "Australian Eastern Daylight Time" AND domain:au
842#
843# Here "Summer" seems quite a bit more popular than "Daylight",
844# particularly when we know the time zone is Australian and not US,
845# say. The "Australian" prefix seems to be popular for Eastern Summer
846# Time, but unpopular for Eastern Daylight Time.
847#
848# For abbreviations, tools like AltaVista are less useful because of
849# ambiguity. Many hits are not really time zones, unfortunately, and
850# many hits denote US time zones and not Australian ones. But here
851# are the hit counts anyway:
852#
853# 161,304 "EST" and domain:au
854# 25,156 "EDT" and domain:au
855# 18,263 "AEST" and domain:au
856# 10,416 "AEDT" and domain:au
857#
858# 14,538 "CST" and domain:au
859# 5,728 "CDT" and domain:au
860# 176 "ACST" and domain:au
861# 29 "ACDT" and domain:au
862#
863# 7,539 "WST" and domain:au
864# 68 "AWST" and domain:au
865#
866# This data suggest that Australians tend to omit the "A" prefix in
867# practice. The situation for "ST" versus "DT" is less clear, given
868# the ambiguities involved.
869#
870# * How do Australians feel about the abbreviations in the tz database?
871#
872# If you just count Australians on this list, I count 2 in favor and 3
873# against. One of the "against" votes (David Keegel) counseled delay,
874# saying that both AEST/AEDT and EST/EST are widely used and
875# understood in Australia.

1142# From Scott Harrington (2001-08-29):
1143# On KQED's "City Arts and Lectures" program last night I heard an
1144# interesting story about daylight savings time. Dr. John Heilbron was
1145# discussing his book "The Sun in the Church: Cathedrals as Solar
1146# Observatories"[1], and in particular the Shrine of Remembrance[2] located
1147# in Melbourne, Australia.
1148#
1149# Apparently the shrine's main purpose is a beam of sunlight which
1150# illuminates a special spot on the floor at the 11th hour of the 11th day
1151# of the 11th month (Remembrance Day) every year in memory of Australia's
1152# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
1153# you will indeed see the sunbeam illuminate the special spot at the
1154# expected time.
1155#
1156# However, that is only because of some special mirror contraption that had
1157# to be employed, since due to daylight savings time, the true solar time of
1158# the remembrance moment occurs one hour later (or earlier?). Perhaps
1159# someone with more information on this jury-rig can tell us more.

1504# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST

1506# standard time in 1940s, Tonga had the choice of subtracting from its

1508# advancing its time to maintain the differential of 13 degrees
1509# (approximately 50 minutes ahead of New Zealand time).
1510#
1511# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1512# Tungi, preferred to ensure Tonga's title as the land where time
1513# begins, the Legislative Assembly approved the latter change.
1514#
1515# But some of the older, more conservative members from the outer

1517# minutes, as your Royal Highness wishes, what becomes of the 40
1518# minutes we have lost?"

1527# From Eric Ulevik (1999-05-03):
1528# Tonga's director of tourism, who is also secretary of the National Millenium
1529# Committee, has a plan to get Tonga back in front.
1530# He has proposed a one-off move to tropical daylight saving for Tonga from
1531# October to March, which has won approval in principle from the Tongan
1532# Government.

1542# I have not been able to find exact dates for the transition in November
1543# yet. By reading this article it seems like Fiji will be 14 hours ahead
1544# of UTC as well, but as far as I know Fiji will only be 13 hours ahead
1545# (12 + 1 hour DST).

1551# "Daylight Savings Time will take effect on Oct. 2 through April 15, 2000
1552# and annually thereafter from the first Saturday in October through the
1553# third Saturday of April. Under the system approved by Privy Council on
1554# Sept. 10, clocks must be turned ahead one hour on the opening day and
1555# set back an hour on the closing date."
1556# Alas, no indication of the time of day.
1557
1558# From Rives McDow (1999-10-06):
1559# Tonga started its Daylight Saving on Saturday morning October 2nd at 0200am.
1560# Daylight Saving ends on April 16 at 0300am which is Sunday morning.
1561
1562# From Steffen Thorsen (2000-10-31):
1563# Back in March I found a notice on the website http://www.tongaonline.com
1564# that Tonga changed back to standard time one month early, on March 19
1565# instead of the original reported date April 16. Unfortunately, the article
1566# is no longer available on the site, and I did not make a copy of the
1567# text, and I have forgotten to report it here.

1573# From Sione Moala-Mafi (2001-09-20) via Rives McDow:
1574# At 2:00am on the first Sunday of November, the standard time in the Kingdom
1575# shall be moved forward by one hour to 3:00am. At 2:00am on the last Sunday
1576# of January the standard time in the Kingdom shall be moved backward by one

1585# From Vernice Anderson, Personal Secretary to Philip Jessup,
1586# US Ambassador At Large (oral history interview, 1971-02-02):
1587#
1588# Saturday, the 14th [of October, 1950] -- ... The time was all the
1589# more confusing at that point, because we had crossed the
1590# International Date Line, thus getting two Sundays. Furthermore, we
1591# discovered that Wake Island had two hours of daylight saving time
1592# making calculation of time in Washington difficult if not almost
1593# impossible.

1602# The International Date Line
1603
1604# From Gwillim Law (2000-01-03):
1605#
1606# The International Date Line is not defined by any international standard,
1607# convention, or treaty. Mapmakers are free to draw it as they please.
1608# Reputable mapmakers will simply ensure that every point of land appears on
1609# the correct side of the IDL, according to the date legally observed there.
1610#
1611# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1612# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1613# to the east side of the Phoenix and Line Islands), I suppose that most
1614# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
1615# has a rather arbitrary nature. The straight-line boundaries between Pacific
1616# island nations that are shown on many maps are based on an international
e1e23b59 1617# convention, but are not legally binding national borders.... The date is
984263bc
MD
1618# governed by the IDL; therefore, even on the high seas, there may be some
1619# places as late as fourteen hours later than UTC. And, since the IDL is not
1620# an international standard, there are some places on the high seas where the
1621# correct date is ambiguous.

1623# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
1624# Before 1920, all ships kept local apparent time on the high seas by setting
1625# their clocks at night or at the morning sight so that, given the ship's
1626# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
1627# meridian (12 o'clock = local apparent noon). During 1917, at the
1628# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
1629# ships, both military and civilian, should adopt hourly standard time zones
1630# on the high seas. Whenever a ship was within the territorial waters of any
1631# nation it would use that nation's standard time. The captain was permitted
1632# to change his ship's clocks at a time of his choice following his ship's
1633# entry into another zone time--he often chose midnight. These zones were
1634# adopted by all major fleets between 1920 and 1925 but not by many
1635# independent merchant ships until World War II.
