453 # Australia
455 # From John Mackin (March 6, 1991):
456 # We in Australia have _never_ referred to DST as `daylight' time.
457 # It is called `summer' time. Now by a happy coincidence, `summer'
458 # and `standard' happen to start with the same letter; hence, the
459 # abbreviation does _not_ change...
460 # The legislation does not actually define abbreviations, at least
461 # in this State, but the abbreviation is just commonly taken to be the
462 # initials of the phrase, and the legislation here uniformly uses
463 # the phrase `summer time' and does not use the phrase `daylight
464 # time'.
465 # Announcers on the Commonwealth radio network, the ABC (for Australian
466 # Broadcasting Commission), use the phrases `Eastern Standard Time'
467 # or `Eastern Summer Time'. (Note, though, that as I say in the
468 # current australasia file, there is really no such thing.) Announcers
469 # on its overseas service, Radio Australia, use the same phrases
470 # prefixed by the word `Australian' when referring to local times;
471 # time announcements on that service, naturally enough, are made in UTC.
473 # From Arthur David Olson (March 8 1992):
474 # Given the above, what's chosen for year-round use is:
475 # CST for any place operating at a GMTOFF of 9:30
476 # WST for any place operating at a GMTOFF of 8:00
477 # EST for any place operating at a GMTOFF of 10:00
479 # From Paul Eggert (1995-12-19):
480 # Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
481 # Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
482 # reports that NSW's fall 1995 change will occur at 2:00,
483 # but Robert Elz says it's been 3:00 in Victoria since 1970
484 # and perhaps the newspaper's `2:00' is referring to standard time.
485 # For now we'll continue to assume 2:00s for changes since 1960.
