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.

448 # From Paul Eggert <eggert@twinsun.com> (1996-11-22):
449 # A good source for time zone historical data outside the U.S. is

451 # San Diego: ACS Publications, Inc. (1991).

453 # Gwillim Law <LAW@encmail.encompass.com> writes that a good source
454 # for recent time zone data is the International Air Transport
455 # Association's Standard Schedules Information Manual (IATA SSIM),
456 # published semiannually. Law sent in several helpful summaries
457 # of the IATA's data after 1990.
458 #
459 # Except where otherwise noted, Shanks is the source for entries through 1990,
460 # and IATA SSIM is the source for entries after 1990.

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

871 # From Paul Eggert (1995-12-19);
872 # Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
873 # Robert Uzgalis <buz@cs.aukuni.ac.nz> writes that the New Zealand Daylight
874 # Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard
875 # time on both the first Sunday in October and the third Sunday in March.
876 # As with Australia, we'll assume the tradition is 2:00s, not 2:00.
877 #
878 # From Paul Eggert (1996-11-22):
879 # Shanks gives no data for Chatham; usno1989 says it's +12:45,
880 # usno1995 says it's +12:45/+13:45, and IATA SSIM (1991/1996)
881 # gives the NZ rules but with transitions at 2:45 local standard time.
882 # Guess that they adopted DST in 1990.

886 # Fiji
888 # Howse writes (p 162) that in 1879 the British governor of Fiji
889 # enacted an ordinance standardizing the islands on +12:00.
890 # Perhaps it didn't take. We go with Shanks's more precise date in 1915.
892 # Johnston
894 # Johnston data is from usno1995.
896 # Kiribati
898 # From Paul Eggert (1996-01-22):
899 # Today's _Wall Street Journal_ (page 1) reports that Kiribati
900 # ``declared it the same day throught the country as of Jan. 1, 1995''
901 # as part of the competition to be first into the 21st century.
903 # Kwajalein
905 # In comp.risks 14.87 (26 August 1993), Peter Neumann writes:
906 # I wonder what happened in Kwajalein, where there was NO Friday,
907 # 1993-08-20. Thursday night at midnight Kwajalein switched sides with
908 # respect to the International Date Line, to rejoin its fellow islands,
909 # going from 11:59 p.m. Thursday to 12:00 m. Saturday in a blink.
911 # N Mariana Is, Guam
913 # Howse writes (p 162) ``The Spaniards, on the other hand, reached the
914 # Philippines and the Ladrones from America,'' and implies that the Ladrones
915 # (now called the Marianas) kept American date for quite some time.
916 # Ignore this for now, as we have no hard data. See also Asia/Manila.
918 # Micronesia
920 # Alan Eugene Davis <adavis@kuentos.guam.net> writes (1996-03-16),
921 # ``I am certain, having lived there for the past decade, that "Truk"
922 # (now properly known as Chuuk) ... is in the time zone GMT+10.''

924 # Shanks writes that Truk switched from GMT+10 to GMT+11 on 1978-10-01;
925 # ignore this for now.
927 # Samoa
929 # Howse writes that in 1879 the King of Samoa decided to change
930 # ``the date in his kingdom from the Antipodean to the American system,
931 # ordaining -- by a masterpiece of diplomatic flattery -- that
932 # the Fourth of July should be celebrated twice in that year.''
934 # Tonga
936 # From Paul Eggert (1996-01-22):
937 # Today's _Wall Street Journal_ (p 1) reports that ``Tonga has been plotting
938 # to sneak ahead of [New Zealanders] by introducing daylight-saving time.''
939 # Since Kiribati has moved the Date Line it's not clear what Tonga will do.
