43 # Queensland ceased to.
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,

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

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