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,

421 # From Paul Eggert <eggert@twinsun.com> (1996-11-22):

429 # published semiannually. Law sent in several helpful summaries
430 # of the IATA's data after 1990.

468 # From John Mackin (1991-03-06):
469 # We in Australia have _never_ referred to DST as `daylight' time.
470 # It is called `summer' time. Now by a happy coincidence, `summer'
471 # and `standard' happen to start with the same letter; hence, the
472 # abbreviation does _not_ change...
473 # The legislation does not actually define abbreviations, at least
474 # in this State, but the abbreviation is just commonly taken to be the
475 # initials of the phrase, and the legislation here uniformly uses
476 # the phrase `summer time' and does not use the phrase `daylight
478 # Announcers on the Commonwealth radio network, the ABC (for Australian
479 # Broadcasting Commission), use the phrases `Eastern Standard Time'
480 # or `Eastern Summer Time'. (Note, though, that as I say in the
481 # current australasia file, there is really no such thing.) Announcers
482 # on its overseas service, Radio Australia, use the same phrases
483 # prefixed by the word `Australian' when referring to local times;
484 # time announcements on that service, naturally enough, are made in UTC.
486 # From Arthur David Olson (March 8 1992):
487 # Given the above, what's chosen for year-round use is:
488 # CST for any place operating at a GMTOFF of 9:30
489 # WST for any place operating at a GMTOFF of 8:00
