41# From Alex Livingston <alex@agsm.unsw.edu.au> (1996-11-01):
42# I have heard or read more than once that some resort islands off the coast
43# of Queensland chose to keep observing daylight-saving time even after
44# Queensland ceased to.
45#
46# From Paul Eggert (1996-11-22):
47# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
48# Hamilton) observed DST for two years after the rest of Queensland stopped.
49# Hamilton is the largest, but there is also a Hamilton in Victoria,
50# so use Lindeman.

520# <a href="http://www.dstc.qut.edu.au/DST/marg/daylight.html">
521# Australia's Daylight Saving Times
522# </a>, by Margaret Turner, summarizes daylight saving issues in Australia.
523
524# From John Mackin (1991-03-06):
525# We in Australia have _never_ referred to DST as `daylight' time.
526# It is called `summer' time. Now by a happy coincidence, `summer'
527# and `standard' happen to start with the same letter; hence, the
528# abbreviation does _not_ change...
529# The legislation does not actually define abbreviations, at least
530# in this State, but the abbreviation is just commonly taken to be the
531# initials of the phrase, and the legislation here uniformly uses
532# the phrase `summer time' and does not use the phrase `daylight
533# time'.
534# Announcers on the Commonwealth radio network, the ABC (for Australian
535# Broadcasting Commission), use the phrases `Eastern Standard Time'
536# or `Eastern Summer Time'. (Note, though, that as I say in the
537# current australasia file, there is really no such thing.) Announcers
538# on its overseas service, Radio Australia, use the same phrases
539# prefixed by the word `Australian' when referring to local times;
540# time announcements on that service, naturally enough, are made in UTC.
541
542# From Arthur David Olson (1992-03-08):
543# Given the above, what's chosen for year-round use is:
544# CST for any place operating at a GMTOFF of 9:30
545# WST for any place operating at a GMTOFF of 8:00
546# EST for any place operating at a GMTOFF of 10:00
547
548# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
549# versus "AEST" etc.:
550#
551# I see the following points of dispute:
552#
553# * How important are unique time zone abbreviations?
554#
555# Here I tend to agree with the point (most recently made by Chris
556# Newman) that unique abbreviations should not be essential for proper
557# operation of software. We have other instances of ambiguity
558# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
559# Standard Time"), and they are not likely to go away any time soon.
560# In the old days, some software mistakenly relied on unique
561# abbreviations, but this is becoming less true with time, and I don't
562# think it's that important to cater to such software these days.
563#
564# On the other hand, there is another motivation for unambiguous
565# abbreviations: it cuts down on human confusion. This is
566# particularly true for Australia, where "EST" can mean one thing for
567# time T and a different thing for time T plus 1 second.
568#
569# * Does the relevant legislation indicate which abbreviations should be used?
570#
571# Here I tend to think that things are a mess, just as they are in
572# many other countries. We Americans are currently disagreeing about
573# which abbreviation to use for the newly legislated Chamorro Standard
574# Time, for example.
575#
576# Personally, I would prefer to use common practice; I would like to
577# refer to legislation only for examples of common practice, or as a
578# tiebreaker.
579#
580# * Do Australians more often use "Eastern Daylight Time" or "Eastern
581# Summer Time"? Do they typically prefix the time zone names with
582# the word "Australian"?
583#
584# My own impression is that both "Daylight Time" and "Summer Time" are
585# common and are widely understood, but that "Summer Time" is more
586# popular; and that the leading "A" is also common but is omitted more
587# often than not. I just used AltaVista advanced search and got the
588# following count of page hits:
589#
590# 1,103 "Eastern Summer Time" AND domain:au
591# 971 "Australian Eastern Summer Time" AND domain:au
592# 613 "Eastern Daylight Time" AND domain:au
593# 127 "Australian Eastern Daylight Time" AND domain:au
594#
595# Here "Summer" seems quite a bit more popular than "Daylight",
596# particularly when we know the time zone is Australian and not US,
597# say. The "Australian" prefix seems to be popular for Eastern Summer
598# Time, but unpopular for Eastern Daylight Time.
599#
600# For abbreviations, tools like AltaVista are less useful because of
601# ambiguity. Many hits are not really time zones, unfortunately, and
602# many hits denote US time zones and not Australian ones. But here
603# are the hit counts anyway:
604#
605# 161,304 "EST" and domain:au
606# 25,156 "EDT" and domain:au
607# 18,263 "AEST" and domain:au
608# 10,416 "AEDT" and domain:au
609#
610# 14,538 "CST" and domain:au
611# 5,728 "CDT" and domain:au
612# 176 "ACST" and domain:au
613# 29 "ACDT" and domain:au
614#
615# 7,539 "WST" and domain:au
616# 68 "AWST" and domain:au
617#
618# This data suggest that Australians tend to omit the "A" prefix in
619# practice. The situation for "ST" versus "DT" is less clear, given
620# the ambiguities involved.
621#
622# * How do Australians feel about the abbreviations in the tz database?
623#
624# If you just count Australians on this list, I count 2 in favor and 3
625# against. One of the "against" votes (David Keegel) counseled delay,
626# saying that both AEST/AEDT and EST/EST are widely used and
627# understood in Australia.
628
629# From Paul Eggert (1995-12-19):
630# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
631# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
632# reports that NSW's fall 1995 change will occur at 2:00,
633# but Robert Elz says it's been 3:00 in Victoria since 1970
634# and perhaps the newspaper's `2:00' is referring to standard time.
635# For now we'll continue to assume 2:00s for changes since 1960.

847# discussing his book "The Sun in the Church: Cathedrals as Solar
848# Observatories"[1], and in particular the Shrine of Remembrance[2] located
849# in Melbourne, Australia.
850#
851# Apparently the shrine's main purpose is a beam of sunlight which
852# illuminates a special spot on the floor at the 11th hour of the 11th day
853# of the 11th month (Remembrance Day) every year in memory of Australia's
854# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
855# you will indeed see the sunbeam illuminate the special spot at the
856# expected time.
857#
858# However, that is only because of some special mirror contraption that had
859# to be employed, since due to daylight savings time, the true solar time of
860# the remembrance moment occurs one hour later (or earlier?). Perhaps
861# someone with more information on this jury-rig can tell us more.

869# New South Wales and subjurisdictions have their own ideas of a fun time.
870# Based on law library research by John Mackin (john@basser.cs.su.oz),
871# who notes:
872# In Australia, time is not legislated federally, but rather by the
873# individual states. Thus, while such terms as ``Eastern Standard Time''
874# [I mean, of course, Australian EST, not any other kind] are in common
875# use, _they have NO REAL MEANING_, as they are not defined in the
876# legislation. This is very important to understand.

1157# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
1158# How Tonga became `The Land where Time Begins'
1159# </a>:
1160
1161# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
1162# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
1163# standard time in 1940s, Tonga had the choice of subtracting from its
1164# local time to come on the same standard time as New Zealand or of
1165# advancing its time to maintain the differential of 13 degrees
1166# (approximately 50 minutes ahead of New Zealand time).
1167#
1168# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1169# Tungi, preferred to ensure Tonga's title as the land where time
1170# begins, the Legislative Assembly approved the latter change.
1171#
1172# But some of the older, more conservative members from the outer
1173# islands objected. "If at midnight on Dec. 31, we move ahead 40
1174# minutes, as your Royal Highness wishes, what becomes of the 40
1175# minutes we have lost?"
1176#
1177# The Crown Prince, presented an unanswerable argument: "Remember that
1178# on the World Day of Prayer, you would be the first people on Earth
1179# to say your prayers in the morning."

1238# The International Date Line
1239
1240# From Gwillim Law (2000-01-03):
1241#
1242# The International Date Line is not defined by any international standard,
1243# convention, or treaty. Mapmakers are free to draw it as they please.
1244# Reputable mapmakers will simply ensure that every point of land appears on
1245# the correct side of the IDL, according to the date legally observed there.
1246#
1247# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1248# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1249# to the east side of the Phoenix and Line Islands), I suppose that most
1250# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
1251# has a rather arbitrary nature. The straight-line boundaries between Pacific
1252# island nations that are shown on many maps are based on an international
1253# convention, but are not legally binding national borders.
1254#
1255# An Anglo-French Conference on Time-Keeping at Sea (June, 1917) agreed that
1256# legal time on the high seas would be zone time, i.e., the standard time at

42# I have heard or read more than once that some resort islands off the coast
43# of Queensland chose to keep observing daylight-saving time even after
44# Queensland ceased to.
45#
46# From Paul Eggert (1996-11-22):
47# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
48# Hamilton) observed DST for two years after the rest of Queensland stopped.
49# Hamilton is the largest, but there is also a Hamilton in Victoria,
50# so use Lindeman.

520# <a href="http://www.dstc.qut.edu.au/DST/marg/daylight.html">
521# Australia's Daylight Saving Times
522# </a>, by Margaret Turner, summarizes daylight saving issues in Australia.
523
524# From John Mackin (1991-03-06):
525# We in Australia have _never_ referred to DST as `daylight' time.
526# It is called `summer' time. Now by a happy coincidence, `summer'
527# and `standard' happen to start with the same letter; hence, the
528# abbreviation does _not_ change...
529# The legislation does not actually define abbreviations, at least
530# in this State, but the abbreviation is just commonly taken to be the
531# initials of the phrase, and the legislation here uniformly uses
532# the phrase `summer time' and does not use the phrase `daylight
533# time'.
534# Announcers on the Commonwealth radio network, the ABC (for Australian
535# Broadcasting Commission), use the phrases `Eastern Standard Time'
536# or `Eastern Summer Time'. (Note, though, that as I say in the
537# current australasia file, there is really no such thing.) Announcers
538# on its overseas service, Radio Australia, use the same phrases
539# prefixed by the word `Australian' when referring to local times;
540# time announcements on that service, naturally enough, are made in UTC.
541
542# From Arthur David Olson (1992-03-08):
543# Given the above, what's chosen for year-round use is:
544# CST for any place operating at a GMTOFF of 9:30
545# WST for any place operating at a GMTOFF of 8:00
546# EST for any place operating at a GMTOFF of 10:00
547
548# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
549# versus "AEST" etc.:
550#
551# I see the following points of dispute:
552#
553# * How important are unique time zone abbreviations?
554#
555# Here I tend to agree with the point (most recently made by Chris
556# Newman) that unique abbreviations should not be essential for proper
557# operation of software. We have other instances of ambiguity
558# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
559# Standard Time"), and they are not likely to go away any time soon.
560# In the old days, some software mistakenly relied on unique
561# abbreviations, but this is becoming less true with time, and I don't
562# think it's that important to cater to such software these days.
563#
564# On the other hand, there is another motivation for unambiguous
565# abbreviations: it cuts down on human confusion. This is
566# particularly true for Australia, where "EST" can mean one thing for
567# time T and a different thing for time T plus 1 second.
568#
569# * Does the relevant legislation indicate which abbreviations should be used?
570#
571# Here I tend to think that things are a mess, just as they are in
572# many other countries. We Americans are currently disagreeing about
573# which abbreviation to use for the newly legislated Chamorro Standard
574# Time, for example.
575#
576# Personally, I would prefer to use common practice; I would like to
577# refer to legislation only for examples of common practice, or as a
578# tiebreaker.
579#
580# * Do Australians more often use "Eastern Daylight Time" or "Eastern
581# Summer Time"? Do they typically prefix the time zone names with
582# the word "Australian"?
583#
584# My own impression is that both "Daylight Time" and "Summer Time" are
585# common and are widely understood, but that "Summer Time" is more
586# popular; and that the leading "A" is also common but is omitted more
587# often than not. I just used AltaVista advanced search and got the
588# following count of page hits:
589#
590# 1,103 "Eastern Summer Time" AND domain:au
591# 971 "Australian Eastern Summer Time" AND domain:au
592# 613 "Eastern Daylight Time" AND domain:au
593# 127 "Australian Eastern Daylight Time" AND domain:au
594#
595# Here "Summer" seems quite a bit more popular than "Daylight",
596# particularly when we know the time zone is Australian and not US,
597# say. The "Australian" prefix seems to be popular for Eastern Summer
598# Time, but unpopular for Eastern Daylight Time.
599#
600# For abbreviations, tools like AltaVista are less useful because of
601# ambiguity. Many hits are not really time zones, unfortunately, and
602# many hits denote US time zones and not Australian ones. But here
603# are the hit counts anyway:
604#
605# 161,304 "EST" and domain:au
606# 25,156 "EDT" and domain:au
607# 18,263 "AEST" and domain:au
608# 10,416 "AEDT" and domain:au
609#
610# 14,538 "CST" and domain:au
611# 5,728 "CDT" and domain:au
612# 176 "ACST" and domain:au
613# 29 "ACDT" and domain:au
614#
615# 7,539 "WST" and domain:au
616# 68 "AWST" and domain:au
617#
618# This data suggest that Australians tend to omit the "A" prefix in
619# practice. The situation for "ST" versus "DT" is less clear, given
620# the ambiguities involved.
621#
622# * How do Australians feel about the abbreviations in the tz database?
623#
624# If you just count Australians on this list, I count 2 in favor and 3
625# against. One of the "against" votes (David Keegel) counseled delay,
626# saying that both AEST/AEDT and EST/EST are widely used and
627# understood in Australia.
628
629# From Paul Eggert (1995-12-19):
630# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
631# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
632# reports that NSW's fall 1995 change will occur at 2:00,
633# but Robert Elz says it's been 3:00 in Victoria since 1970
634# and perhaps the newspaper's `2:00' is referring to standard time.
635# For now we'll continue to assume 2:00s for changes since 1960.

844# From Scott Harrington (2001-08-29):
845# On KQED's "City Arts and Lectures" program last night I heard an
846# interesting story about daylight savings time. Dr. John Heilbron was
847# discussing his book "The Sun in the Church: Cathedrals as Solar
848# Observatories"[1], and in particular the Shrine of Remembrance[2] located
849# in Melbourne, Australia.
850#
851# Apparently the shrine's main purpose is a beam of sunlight which
852# illuminates a special spot on the floor at the 11th hour of the 11th day
853# of the 11th month (Remembrance Day) every year in memory of Australia's
854# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
855# you will indeed see the sunbeam illuminate the special spot at the
856# expected time.
857#
858# However, that is only because of some special mirror contraption that had
859# to be employed, since due to daylight savings time, the true solar time of
860# the remembrance moment occurs one hour later (or earlier?). Perhaps
861# someone with more information on this jury-rig can tell us more.

871# who notes:
872# In Australia, time is not legislated federally, but rather by the
873# individual states. Thus, while such terms as ``Eastern Standard Time''
874# [I mean, of course, Australian EST, not any other kind] are in common

1158# How Tonga became `The Land where Time Begins'
1159# </a>:
1160
1161# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
1162# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
1163# standard time in 1940s, Tonga had the choice of subtracting from its

1165# advancing its time to maintain the differential of 13 degrees
1166# (approximately 50 minutes ahead of New Zealand time).
1167#
1168# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1169# Tungi, preferred to ensure Tonga's title as the land where time
1170# begins, the Legislative Assembly approved the latter change.
1171#
1172# But some of the older, more conservative members from the outer
1173# islands objected. "If at midnight on Dec. 31, we move ahead 40
1174# minutes, as your Royal Highness wishes, what becomes of the 40
1175# minutes we have lost?"
1176#
1177# The Crown Prince, presented an unanswerable argument: "Remember that
1178# on the World Day of Prayer, you would be the first people on Earth
1179# to say your prayers in the morning."

1238# The International Date Line
1239
1240# From Gwillim Law (2000-01-03):
1241#
1242# The International Date Line is not defined by any international standard,
1243# convention, or treaty. Mapmakers are free to draw it as they please.
1244# Reputable mapmakers will simply ensure that every point of land appears on
1245# the correct side of the IDL, according to the date legally observed there.
1246#
1247# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1248# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1249# to the east side of the Phoenix and Line Islands), I suppose that most
1250# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
1251# has a rather arbitrary nature. The straight-line boundaries between Pacific
1252# island nations that are shown on many maps are based on an international

1255# An Anglo-French Conference on Time-Keeping at Sea (June, 1917) agreed that
1256# legal time on the high seas would be zone time, i.e., the standard time at
1257# the nearest meridian that is a multiple of fifteen degrees. The date is
1258# governed by the IDL; therefore, even on the high seas, there may be some
1259# places as late as fourteen hours later than UTC. And, since the IDL is not
1260# an international standard, there are some places on the high seas where the
1261# correct date is ambiguous.
