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.

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

434
435# From Paul Eggert <eggert@twinsun.com> (1996-11-22):
436# A good source for time zone historical data outside the U.S. is
437# Thomas G. Shanks, The International Atlas (3rd edition),
438# San Diego: ACS Publications, Inc. (1991).
439#
440# Gwillim Law <LAW@encmail.encompass.com> writes that a good source
441# for recent time zone data is the International Air Transport
442# Association's Standard Schedules Information Manual (IATA SSIM),
443# published semiannually. Law sent in several helpful summaries
444# of the IATA's data after 1990.
445#
446# Except where otherwise noted, Shanks is the source for entries through 1990,
447# and IATA SSIM is the source for entries after 1990.
448#
449# Another source occasionally used is Edward W. Whitman, World Time Differences,
450# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
451# I found in the UCLA library.
452#
453# A reliable and entertaining source about time zones is

480# Australia
481
482# From John Mackin (1991-03-06):
483# We in Australia have _never_ referred to DST as `daylight' time.
484# It is called `summer' time. Now by a happy coincidence, `summer'
485# and `standard' happen to start with the same letter; hence, the
486# abbreviation does _not_ change...
487# The legislation does not actually define abbreviations, at least
488# in this State, but the abbreviation is just commonly taken to be the
489# initials of the phrase, and the legislation here uniformly uses
490# the phrase `summer time' and does not use the phrase `daylight
491# time'.
492# Announcers on the Commonwealth radio network, the ABC (for Australian
493# Broadcasting Commission), use the phrases `Eastern Standard Time'
494# or `Eastern Summer Time'. (Note, though, that as I say in the
495# current australasia file, there is really no such thing.) Announcers
496# on its overseas service, Radio Australia, use the same phrases
497# prefixed by the word `Australian' when referring to local times;
498# time announcements on that service, naturally enough, are made in UTC.
499
500# From Arthur David Olson (March 8 1992):
501# Given the above, what's chosen for year-round use is:
502# CST for any place operating at a GMTOFF of 9:30
503# WST for any place operating at a GMTOFF of 8:00
504# EST for any place operating at a GMTOFF of 10:00
505
506# From Paul Eggert (1995-12-19):
507# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
508# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
509# reports that NSW's fall 1995 change will occur at 2:00,
510# but Robert Elz says it's been 3:00 in Victoria since 1970
511# and perhaps the newspaper's `2:00' is referring to standard time.
512# For now we'll continue to assume 2:00s for changes since 1960.

837# From Arthur David Olson (1992-03-08):
838# The chosen rules use the Davies October 8 values for the start of DST in 1989
839# rather than the October 1 value.
840
841# From Paul Eggert (1995-12-19);
842# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
843# Robert Uzgalis <buz@cs.aukuni.ac.nz> writes that the New Zealand Daylight
844# Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard
845# time on both the first Sunday in October and the third Sunday in March.
846# As with Australia, we'll assume the tradition is 2:00s, not 2:00.
847#
848# From Paul Eggert (1996-11-22):
849# Shanks gives no data for Chatham; usno1989 says it's +12:45,
850# usno1995 says it's +12:45/+13:45, and IATA SSIM (1991/1996)
851# gives the NZ rules but with transitions at 2:45 local standard time.
852# Guess that they adopted DST in 1990.

856# Fiji
857
858# Howse writes (p 162) that in 1879 the British governor of Fiji
859# enacted an ordinance standardizing the islands on +12:00.
860# Perhaps it didn't take. We go with Shanks's more precise date in 1915.

868# From Paul Eggert (1996-01-22):

871# as part of the competition to be first into the 21st century.

873# Kwajalein
874
875# In comp.risks 14.87 (26 August 1993), Peter Neumann writes:
876# I wonder what happened in Kwajalein, where there was NO Friday,
877# 1993-08-20. Thursday night at midnight Kwajalein switched sides with

882
883# Howse writes (p 162) ``The Spaniards, on the other hand, reached the

885# (now called the Marianas) kept American date for quite some time.

890# Alan Eugene Davis <adavis@kuentos.guam.net> writes (1996-03-16),

892# (now properly known as Chuuk) ... is in the time zone GMT+10.''
893#
894# Shanks writes that Truk switched from GMT+10 to GMT+11 on 1978-10-01;
895# ignore this for now.
896
897# Samoa
898
899# Howse writes that in 1879 the King of Samoa decided to change
900# ``the date in his kingdom from the Antipodean to the American system,
901# ordaining -- by a masterpiece of diplomatic flattery -- that
902# the Fourth of July should be celebrated twice in that year.''
903
904# Tonga
905
906# From Paul Eggert (1996-01-22):
907# Today's _Wall Street Journal_ (p 1) reports that ``Tonga has been plotting
908# to sneak ahead of [New Zealanders] by introducing daylight-saving time.''
909# Since Kiribati has moved the Date Line it's not clear what Tonga will do.

431# This data is by no means authoritative; if you think you know better,
432# go ahead and edit the file (and please send any changes to
433# tz@elsie.nci.nih.gov for general use in the future).
434
435# From Paul Eggert <eggert@twinsun.com> (1996-11-22):
436# A good source for time zone historical data outside the U.S. is
437# Thomas G. Shanks, The International Atlas (3rd edition),
438# San Diego: ACS Publications, Inc. (1991).
439#
440# Gwillim Law <LAW@encmail.encompass.com> writes that a good source
441# for recent time zone data is the International Air Transport
442# Association's Standard Schedules Information Manual (IATA SSIM),
443# published semiannually. Law sent in several helpful summaries
444# of the IATA's data after 1990.
445#
446# Except where otherwise noted, Shanks is the source for entries through 1990,
447# and IATA SSIM is the source for entries after 1990.
448#
449# Another source occasionally used is Edward W. Whitman, World Time Differences,
450# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
451# I found in the UCLA library.
452#
453# A reliable and entertaining source about time zones is
454# Derek Howse, Greenwich time and the discovery of the longitude,
455# Oxford University Press (1980).
456#
457# I invented the abbreviations marked `*' in the following table;

480# Australia
481
482# From John Mackin (1991-03-06):
483# We in Australia have _never_ referred to DST as `daylight' time.
484# It is called `summer' time. Now by a happy coincidence, `summer'
485# and `standard' happen to start with the same letter; hence, the
486# abbreviation does _not_ change...
487# The legislation does not actually define abbreviations, at least
488# in this State, but the abbreviation is just commonly taken to be the
489# initials of the phrase, and the legislation here uniformly uses
490# the phrase `summer time' and does not use the phrase `daylight
491# time'.
492# Announcers on the Commonwealth radio network, the ABC (for Australian
493# Broadcasting Commission), use the phrases `Eastern Standard Time'
494# or `Eastern Summer Time'. (Note, though, that as I say in the
495# current australasia file, there is really no such thing.) Announcers
496# on its overseas service, Radio Australia, use the same phrases
497# prefixed by the word `Australian' when referring to local times;
498# time announcements on that service, naturally enough, are made in UTC.
499
500# From Arthur David Olson (March 8 1992):
501# Given the above, what's chosen for year-round use is:
502# CST for any place operating at a GMTOFF of 9:30
503# WST for any place operating at a GMTOFF of 8:00
504# EST for any place operating at a GMTOFF of 10:00
505
506# From Paul Eggert (1995-12-19):
507# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
508# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
509# reports that NSW's fall 1995 change will occur at 2:00,
510# but Robert Elz says it's been 3:00 in Victoria since 1970
511# and perhaps the newspaper's `2:00' is referring to standard time.
512# For now we'll continue to assume 2:00s for changes since 1960.

770
771# From Eric Ulevik <eau@ozemail.com.au> (1997-06-12):
772# The NSW state government in Australia is talking about bringing the start
773# of daylight savings time forward in the year 2000 to cater for the Olympics.
774# This is going to take some time to be negotiated, because the plan is to do
775# this in multiple states due to soccer games (which are not just in Sydney).

803# Lord Howe Island is located off the New South Wales coast, and is half an

805
806# From Paul Eggert (1995-12-19):
807# For Lord Howe we use Shanks through its time of publication (1991).
808# Lord Howe is part of NSW, so we'll guess it has used the same transition
809# times as NSW since 1991, even though Shanks writes that Lord Howe went
810# with Victoria when NSW and Victoria disagreed in 1982.

817# From Mark Davies (1990-10-03):
818# the 1989/90 year was a trial of an extended "daylight saving" period.

840
841# From Paul Eggert (1995-12-19);
842# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
843# Robert Uzgalis <buz@cs.aukuni.ac.nz> writes that the New Zealand Daylight
844# Savings Time Order in Council dated 1990-06-18 specifies 2:00 standard
845# time on both the first Sunday in October and the third Sunday in March.
846# As with Australia, we'll assume the tradition is 2:00s, not 2:00.
847#
848# From Paul Eggert (1996-11-22):
849# Shanks gives no data for Chatham; usno1989 says it's +12:45,
850# usno1995 says it's +12:45/+13:45, and IATA SSIM (1991/1996)
851# gives the NZ rules but with transitions at 2:45 local standard time.
