466 # Australia
468 # From John Mackin (March 6, 1991):
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
477 # time'.
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
490 # EST for any place operating at a GMTOFF of 10:00
492 # From Paul Eggert (1995-12-19):
493 # Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
494 # Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
495 # reports that NSW's fall 1995 change will occur at 2:00,
496 # but Robert Elz says it's been 3:00 in Victoria since 1970
497 # and perhaps the newspaper's `2:00' is referring to standard time.
498 # For now we'll continue to assume 2:00s for changes since 1960.
