39# From Alex Livingston <alex@agsm.unsw.edu.au> (1996-11-01):
40# I have heard or read more than once that some resort islands off the coast
41# of Queensland chose to keep observing daylight-saving time even after
42# Queensland ceased to.
43#
44# From Paul Eggert (1996-11-22):
45# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
46# Hamilton) observed DST for two years after the rest of Queensland stopped.
47# Hamilton is the largest, but there is also a Hamilton in Victoria,
48# so use Lindeman.

482# Except where otherwise noted, Shanks is the source for entries through 1990,

516# <a href="http://www.dstc.qut.edu.au/DST/marg/daylight.html">
517# Australia's Daylight Saving Times
518# </a>, by Margaret Turner, summarizes daylight saving issues in Australia.
519
520# From John Mackin (1991-03-06):
521# We in Australia have _never_ referred to DST as `daylight' time.
522# It is called `summer' time. Now by a happy coincidence, `summer'
523# and `standard' happen to start with the same letter; hence, the
524# abbreviation does _not_ change...
525# The legislation does not actually define abbreviations, at least
526# in this State, but the abbreviation is just commonly taken to be the
527# initials of the phrase, and the legislation here uniformly uses
528# the phrase `summer time' and does not use the phrase `daylight
529# time'.
530# Announcers on the Commonwealth radio network, the ABC (for Australian
531# Broadcasting Commission), use the phrases `Eastern Standard Time'
532# or `Eastern Summer Time'. (Note, though, that as I say in the
533# current australasia file, there is really no such thing.) Announcers
534# on its overseas service, Radio Australia, use the same phrases
535# prefixed by the word `Australian' when referring to local times;
536# time announcements on that service, naturally enough, are made in UTC.
537
538# From Arthur David Olson (March 8 1992):
539# Given the above, what's chosen for year-round use is:
540# CST for any place operating at a GMTOFF of 9:30
541# WST for any place operating at a GMTOFF of 8:00
542# EST for any place operating at a GMTOFF of 10:00
543
544# From Paul Eggert (1995-12-19):
545# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
546# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
547# reports that NSW's fall 1995 change will occur at 2:00,
548# but Robert Elz says it's been 3:00 in Victoria since 1970
549# and perhaps the newspaper's `2:00' is referring to standard time.
550# For now we'll continue to assume 2:00s for changes since 1960.

845# # Yancowinna uses Central Standard Time, despite [its] location on the

862# Lord Howe Island is located off the New South Wales coast, and is half an
863# hour ahead of NSW time.
864
865# From James Lonergan, Secretary, Lord Howe Island Board (2000-01-27):
866# Lord Howe Island summer time in 2000/2001 will commence on the same
867# date as the rest of NSW (i.e. 2000-08-27). For your information the
868# Lord Howe Island Board (controlling authority for the Island) is
869# seeking the community's views on various options for summer time
870# arrangements on the Island, e.g. advance clocks by 1 full hour
871# instead of only 30 minutes. Dependent on the wishes of residents
872# the Board may approach the NSW government to change the existing
873# arrangements. The starting date for summer time on the Island will
874# however always coincide with the rest of NSW.
875
876# From James Lonergan, Secretary, Lord Howe Island Board (2000-10-25):
877# Lord Howe Island advances clocks by 30 minutes during DST in NSW and retards
878# clocks by 30 minutes when DST finishes. Since DST was most recently
879# introduced in NSW, the "changeover" time on the Island has been 02:00 as
880# shown on clocks on LHI. I guess this means that for 30 minutes at the start
881# of DST, LHI is actually 1 hour ahead of the rest of NSW.
882
883# From Paul Eggert (2001-02-09):
884# For Lord Howe dates we use Shanks through 1989, and Lonergan thereafter.
885# For times we use Lonergan.

915# From Paul Eggert (1995-12-19);
916# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.

918# Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard
919# time on both the first Sunday in October and the third Sunday in March.
920# As with Australia, we'll assume the tradition is 2:00s, not 2:00.
921#
922# From Paul Eggert (1999-10-29):
923# Shanks gives no time data for Chatham; usno1989 says it's +12:45,
924# usno1995 says it's +12:45/+13:45, and IATA SSIM (1991/1999)
925# gives the NZ rules but with transitions at 2:45 local standard time.

1045# Today's _Wall Street Journal_ (p 1) reports that ``Tonga has been plotting

1047# Since Kiribati has moved the Date Line it's not clear what Tonga will do.

1049# Don Mundell writes in the 1997-02-20 Tonga Chronicle
1050# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
1051# How Tonga became `The Land where Time Begins'
1052# </a>:
1053
1054# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
1055# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
1056# standard time in 1940s, Tonga had the choice of subtracting from its
1057# local time to come on the same standard time as New Zealand or of
1058# advancing its time to maintain the differential of 13 degrees
1059# (approximately 50 minutes ahead of New Zealand time).
1060#
1061# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1062# Tungi, preferred to ensure Tonga's title as the land where time
1063# begins, the Legislative Assembly approved the latter change.
1064#
1065# But some of the older, more conservative members from the outer
1066# islands objected. "If at midnight on Dec. 31, we move ahead 40
1067# minutes, as your Royal Highness wishes, what becomes of the 40
1068# minutes we have lost?"
1069#
1070# The Crown Prince, presented an unanswerable argument: "Remember that
1071# on the World Day of Prayer, you would be the first people on Earth
1072# to say your prayers in the morning."
1073
1074# From Paul Eggert (1999-08-12):
1075# Shanks says the transition was on 1968-10-01; go with Mundell.
1076
1077# From Eric Ulevik (1999-05-03):
1078# Tonga's director of tourism, who is also secretary of the National Millenium
1079# Committee, has a plan to get Tonga back in front.
1080# He has proposed a one-off move to tropical daylight saving for Tonga from
1081# October to March, which has won approval in principle from the Tongan
1082# Government.

1125# The International Date Line
1126
1127# From Gwillim Law (2000-01-03):
1128#
1129# The International Date Line is not defined by any international standard,
1130# convention, or treaty. Mapmakers are free to draw it as they please.
1131# Reputable mapmakers will simply ensure that every point of land appears on
1132# the correct side of the IDL, according to the date legally observed there.
1133#
1134# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1135# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1136# to the east side of the Phoenix and Line Islands), I suppose that most
1137# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
1138# has a rather arbitrary nature. The straight-line boundaries between Pacific
1139# island nations that are shown on many maps are based on an international
1140# convention, but are not legally binding national borders.
1141#
1142# An Anglo-French Conference on Time-Keeping at Sea (June, 1917) agreed that
1143# legal time on the high seas would be zone time, i.e., the standard time at
1144# the nearest meridian that is a multiple of fifteen degrees. The date is
1145# governed by the IDL; therefore, even on the high seas, there may be some
1146# places as late as fourteen hours later than UTC. And, since the IDL is not
1147# an international standard, there are some places on the high seas where the
1148# correct date is ambiguous.
