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.
44#
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,
49# so use Lindeman.

444# This data is by no means authoritative; if you think you know better,

447
448# From Paul Eggert <eggert@twinsun.com> (1996-11-22):
449# A good source for time zone historical data outside the U.S. is
450# Thomas G. Shanks, The International Atlas (4th edition),
451# San Diego: ACS Publications, Inc. (1995).
452#
453# Gwillim Law <LAW@encmail.encompass.com> writes that a good source
454# for recent time zone data is the International Air Transport
455# Association's Standard Schedules Information Manual (IATA SSIM),
456# published semiannually. Law sent in several helpful summaries
457# of the IATA's data after 1990.
458#
459# Except where otherwise noted, Shanks is the source for entries through 1990,
460# and IATA SSIM is the source for entries after 1990.
461#
462# Another source occasionally used is Edward W. Whitman, World Time Differences,
463# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
464# I found in the UCLA library.
465#
466# A reliable and entertaining source about time zones is

491# Australia
492
493# From John Mackin (1991-03-06):
494# We in Australia have _never_ referred to DST as `daylight' time.
495# It is called `summer' time. Now by a happy coincidence, `summer'
496# and `standard' happen to start with the same letter; hence, the
497# abbreviation does _not_ change...
498# The legislation does not actually define abbreviations, at least
499# in this State, but the abbreviation is just commonly taken to be the
500# initials of the phrase, and the legislation here uniformly uses
501# the phrase `summer time' and does not use the phrase `daylight
502# time'.
503# Announcers on the Commonwealth radio network, the ABC (for Australian
504# Broadcasting Commission), use the phrases `Eastern Standard Time'
505# or `Eastern Summer Time'. (Note, though, that as I say in the
506# current australasia file, there is really no such thing.) Announcers
507# on its overseas service, Radio Australia, use the same phrases
508# prefixed by the word `Australian' when referring to local times;
509# time announcements on that service, naturally enough, are made in UTC.
510
511# From Arthur David Olson (March 8 1992):
512# Given the above, what's chosen for year-round use is:
513# CST for any place operating at a GMTOFF of 9:30
514# WST for any place operating at a GMTOFF of 8:00
515# EST for any place operating at a GMTOFF of 10:00
516
517# From Paul Eggert (1995-12-19):
518# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
519# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
520# reports that NSW's fall 1995 change will occur at 2:00,
521# but Robert Elz says it's been 3:00 in Victoria since 1970
522# and perhaps the newspaper's `2:00' is referring to standard time.
523# For now we'll continue to assume 2:00s for changes since 1960.

844# New Zealand, from Elz' asia 1.1
845# Elz says "no guarantees"
846
847# From Mark Davies (1990-10-03):
848# the 1989/90 year was a trial of an extended "daylight saving" period.
849# This trial was deemed successful and the extended period adopted for
850# subsequent years (with the addition of a further week at the start).

870
871# From Paul Eggert (1995-12-19);
872# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
873# Robert Uzgalis <buz@cs.aukuni.ac.nz> writes that the New Zealand Daylight
874# Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard
875# time on both the first Sunday in October and the third Sunday in March.
876# As with Australia, we'll assume the tradition is 2:00s, not 2:00.
877#
878# From Paul Eggert (1996-11-22):
879# Shanks gives no data for Chatham; usno1989 says it's +12:45,
880# usno1995 says it's +12:45/+13:45, and IATA SSIM (1991/1996)

444# This data is by no means authoritative; if you think you know better,
445# go ahead and edit the file (and please send any changes to

447
448# From Paul Eggert <eggert@twinsun.com> (1996-11-22):
449# A good source for time zone historical data outside the U.S. is
450# Thomas G. Shanks, The International Atlas (4th edition),
451# San Diego: ACS Publications, Inc. (1995).
452#
453# Gwillim Law <LAW@encmail.encompass.com> writes that a good source
454# for recent time zone data is the International Air Transport
455# Association's Standard Schedules Information Manual (IATA SSIM),
456# published semiannually. Law sent in several helpful summaries
457# of the IATA's data after 1990.
458#
459# Except where otherwise noted, Shanks is the source for entries through 1990,
460# and IATA SSIM is the source for entries after 1990.
461#
462# Another source occasionally used is Edward W. Whitman, World Time Differences,
463# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
464# I found in the UCLA library.
465#
466# A reliable and entertaining source about time zones is
467# Derek Howse, Greenwich time and the discovery of the longitude,
468# Oxford University Press (1980).

491# Australia
492
493# From John Mackin (1991-03-06):
494# We in Australia have _never_ referred to DST as `daylight' time.
495# It is called `summer' time. Now by a happy coincidence, `summer'
496# and `standard' happen to start with the same letter; hence, the
497# abbreviation does _not_ change...
498# The legislation does not actually define abbreviations, at least
499# in this State, but the abbreviation is just commonly taken to be the
500# initials of the phrase, and the legislation here uniformly uses
501# the phrase `summer time' and does not use the phrase `daylight
502# time'.
503# Announcers on the Commonwealth radio network, the ABC (for Australian
504# Broadcasting Commission), use the phrases `Eastern Standard Time'
505# or `Eastern Summer Time'. (Note, though, that as I say in the
506# current australasia file, there is really no such thing.) Announcers
507# on its overseas service, Radio Australia, use the same phrases
508# prefixed by the word `Australian' when referring to local times;
509# time announcements on that service, naturally enough, are made in UTC.
510
511# From Arthur David Olson (March 8 1992):
512# Given the above, what's chosen for year-round use is:
513# CST for any place operating at a GMTOFF of 9:30
514# WST for any place operating at a GMTOFF of 8:00
515# EST for any place operating at a GMTOFF of 10:00
516
517# From Paul Eggert (1995-12-19):
518# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
519# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
520# reports that NSW's fall 1995 change will occur at 2:00,
521# but Robert Elz says it's been 3:00 in Victoria since 1970
522# and perhaps the newspaper's `2:00' is referring to standard time.
523# For now we'll continue to assume 2:00s for changes since 1960.

765# Based on law library research by John Mackin (john@basser.cs.su.oz),
766# who notes:
767# In Australia, time is not legislated federally, but rather by the
768# individual states. Thus, while such terms as ``Eastern Standard Time''
769# [I mean, of course, Australian EST, not any other kind] are in common
770# use, _they have NO REAL MEANING_, as they are not defined in the
771# legislation. This is very important to understand.

837# For Lord Howe we use Shanks through 1991.
