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

499 # Australia
501 # From John Mackin (1991-03-06):
502 # We in Australia have _never_ referred to DST as `daylight' time.
503 # It is called `summer' time. Now by a happy coincidence, `summer'
504 # and `standard' happen to start with the same letter; hence, the
505 # abbreviation does _not_ change...
506 # The legislation does not actually define abbreviations, at least
507 # in this State, but the abbreviation is just commonly taken to be the
508 # initials of the phrase, and the legislation here uniformly uses
509 # the phrase `summer time' and does not use the phrase `daylight
510 # time'.
511 # Announcers on the Commonwealth radio network, the ABC (for Australian
512 # Broadcasting Commission), use the phrases `Eastern Standard Time'
513 # or `Eastern Summer Time'. (Note, though, that as I say in the
514 # current australasia file, there is really no such thing.) Announcers
515 # on its overseas service, Radio Australia, use the same phrases
516 # prefixed by the word `Australian' when referring to local times;
517 # time announcements on that service, naturally enough, are made in UTC.
519 # From Arthur David Olson (March 8 1992):
520 # Given the above, what's chosen for year-round use is:
521 # CST for any place operating at a GMTOFF of 9:30
522 # WST for any place operating at a GMTOFF of 8:00
523 # EST for any place operating at a GMTOFF of 10:00
525 # From Paul Eggert (1995-12-19):
526 # Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
527 # Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
528 # reports that NSW's fall 1995 change will occur at 2:00,
529 # but Robert Elz says it's been 3:00 in Victoria since 1970
530 # and perhaps the newspaper's `2:00' is referring to standard time.
531 # For now we'll continue to assume 2:00s for changes since 1960.

879 # From Arthur David Olson (1992-03-08):
880 # The chosen rules use the Davies October 8 values for the start of DST in 1989
881 # rather than the October 1 value.
883 # From Paul Eggert (1995-12-19);
884 # Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
885 # Robert Uzgalis <buz@cs.aukuni.ac.nz> writes that the New Zealand Daylight
886 # Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard
887 # time on both the first Sunday in October and the third Sunday in March.
888 # As with Australia, we'll assume the tradition is 2:00s, not 2:00.
889 #
890 # From Paul Eggert (1996-11-22):
891 # Shanks gives no data for Chatham; usno1989 says it's +12:45,
892 # usno1995 says it's +12:45/+13:45, and IATA SSIM (1991/1996)
893 # gives the NZ rules but with transitions at 2:45 local standard time.
894 # Guess that they adopted DST in 1990.

898 # Fiji
900 # Howse writes that in 1879 the British governor of Fiji
901 # enacted an ordinance standardizing the islands on +12:00.
902 # Perhaps it didn't take. We go with Shanks's more precise date in 1915.
904 # From Rives McDow (1998-10-08):
905 # Fiji will introduce DST effective 0200 local time, 1998-11-01
906 # until 0300 local time 1999-02-28. Each year the DST period will
907 # be from the first Sunday in November until the last Sunday in February.
909 # From the BBC World Service (1998-10-31 11:32 UTC):
910 # The Fijiian government says the main reasons for the time change is to
911 # improve productivity and reduce road accidents. But correspondents say it
912 # also hopes the move will boost Fiji's ability to compete with other pacific
913 # islands in the effort to attract tourists to witness the dawning of the new
914 # millenium.

918 # Johnston data is from usno1995.
920 # Kiribati
922 # From Paul Eggert (1996-01-22):
923 # Today's _Wall Street Journal_ (page 1) reports that Kiribati
924 # ``declared it the same day throught the country as of Jan. 1, 1995''
925 # as part of the competition to be first into the 21st century.
927 # Kwajalein
929 # In comp.risks 14.87 (26 August 1993), Peter Neumann writes:
930 # I wonder what happened in Kwajalein, where there was NO Friday,
931 # 1993-08-20. Thursday night at midnight Kwajalein switched sides with
932 # respect to the International Date Line, to rejoin its fellow islands,
933 # going from 11:59 p.m. Thursday to 12:00 m. Saturday in a blink.
935 # N Mariana Is, Guam
937 # Howse writes ``The Spaniards, on the other hand, reached the
938 # Philippines and the Ladrones from America,'' and implies that the Ladrones
939 # (now called the Marianas) kept American date for quite some time.
940 # Ignore this for now, as we have no hard data. See also Asia/Manila.
942 # Micronesia
944 # Alan Eugene Davis <adavis@kuentos.guam.net> writes (1996-03-16),
945 # ``I am certain, having lived there for the past decade, that "Truk"
946 # (now properly known as Chuuk) ... is in the time zone GMT+10.''
947 #
948 # Shanks writes that Truk switched from GMT+10 to GMT+11 on 1978-10-01;
949 # ignore this for now.
951 # Samoa
953 # Howse writes that in 1879 the King of Samoa decided to change
954 # ``the date in his kingdom from the Antipodean to the American system,
955 # ordaining -- by a masterpiece of diplomatic flattery -- that
956 # the Fourth of July should be celebrated twice in that year.''
958 # Tonga
960 # From Paul Eggert (1996-01-22):
961 # Today's _Wall Street Journal_ (p 1) reports that ``Tonga has been plotting
962 # to sneak ahead of [New Zealanders] by introducing daylight-saving time.''
963 # Since Kiribati has moved the Date Line it's not clear what Tonga will do.
