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