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.
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,

480 # From John Mackin (1991-03-06):
481 # We in Australia have _never_ referred to DST as `daylight' time.
482 # It is called `summer' time. Now by a happy coincidence, `summer'
483 # and `standard' happen to start with the same letter; hence, the
484 # abbreviation does _not_ change...
485 # The legislation does not actually define abbreviations, at least
486 # in this State, but the abbreviation is just commonly taken to be the
487 # initials of the phrase, and the legislation here uniformly uses
488 # the phrase `summer time' and does not use the phrase `daylight
490 # Announcers on the Commonwealth radio network, the ABC (for Australian
491 # Broadcasting Commission), use the phrases `Eastern Standard Time'
492 # or `Eastern Summer Time'. (Note, though, that as I say in the
493 # current australasia file, there is really no such thing.) Announcers
494 # on its overseas service, Radio Australia, use the same phrases
495 # prefixed by the word `Australian' when referring to local times;
496 # time announcements on that service, naturally enough, are made in UTC.
