363 # go ahead and edit the file (and please send any changes to

366 # From Paul Eggert <eggert@twinsun.com> (August 18, 1994):
367 # A good source for time zone historical data outside the U.S. is
368 # Thomas G. Shanks, The International Atlas (3rd edition),
369 # San Diego: ACS Publications, Inc. (1991).
370 # Except where noted, it is the source for the data above.

372 # Another source occasionally used is Edward W. Whitman, World Time Differences,
373 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
374 # I found in the UCLA library.
375 #
376 # A reliable and entertaining source about time zones is
377 # Derek Howse, Greenwich time and the discovery of the longitude,
378 # Oxford University Press (1980).

414 # Australia
416 # From John Mackin (March 6, 1991):
417 # We in Australia have _never_ referred to DST as `daylight' time.
418 # It is called `summer' time. Now by a happy coincidence, `summer'
419 # and `standard' happen to start with the same letter; hence, the
420 # abbreviation does _not_ change...
421 # The legislation does not actually define abbreviations, at least
422 # in this State, but the abbreviation is just commonly taken to be the
423 # initials of the phrase, and the legislation here uniformly uses
424 # the phrase `summer time' and does not use the phrase `daylight
425 # time'.
426 # Announcers on the Commonwealth radio network, the ABC (for Australian
427 # Broadcasting Commission), use the phrases `Eastern Standard Time'
428 # or `Eastern Summer Time'. (Note, though, that as I say in the
429 # current australasia file, there is really no such thing.) Announcers
430 # on its overseas service, Radio Australia, use the same phrases
431 # prefixed by the word `Australian' when referring to local times;
432 # time announcements on that service, naturally enough, are made in UTC.
434 # From Arthur David Olson (March 8 1992):
435 # Given the above, what's chosen for year-round use is:
436 # CST for any place operating at a GMTOFF of 9:30
437 # WST for any place operating at a GMTOFF of 8:00
438 # EST for any place operating at a GMTOFF of 10:00
440 # From Paul Eggert (November 8, 1994):
441 # Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
