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

627
628# From Paul Eggert (2006-03-22):
629# A good source for time zone historical data outside the U.S. is
630# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
631# San Diego: ACS Publications, Inc. (2003).
632#
633# Gwillim Law writes that a good source
634# for recent time zone data is the International Air Transport
635# Association's Standard Schedules Information Manual (IATA SSIM),
636# published semiannually. Law sent in several helpful summaries
637# of the IATA's data after 1990.
638#
639# Except where otherwise noted, Shanks & Pottenger is the source for
640# entries through 1990, and IATA SSIM is the source for entries afterwards.
641#
642# Another source occasionally used is Edward W. Whitman, World Time Differences,
643# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
644# I found in the UCLA library.

684
685# From John Mackin (1991-03-06):
686# We in Australia have _never_ referred to DST as `daylight' time.
687# It is called `summer' time. Now by a happy coincidence, `summer'
688# and `standard' happen to start with the same letter; hence, the
689# abbreviation does _not_ change...
690# The legislation does not actually define abbreviations, at least
691# in this State, but the abbreviation is just commonly taken to be the
692# initials of the phrase, and the legislation here uniformly uses
693# the phrase `summer time' and does not use the phrase `daylight
694# time'.
695# Announcers on the Commonwealth radio network, the ABC (for Australian
696# Broadcasting Commission), use the phrases `Eastern Standard Time'
697# or `Eastern Summer Time'. (Note, though, that as I say in the

708
709# From Chuck Soper (2006-06-01):
710# I recently found this Australian government web page on time zones:
711# <http://www.australia.gov.au/about-australia-13time>
712# And this government web page lists time zone names and abbreviations:
713# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml>
714
715# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
716# versus "AEST" etc.:
717#
718# I see the following points of dispute:
719#
720# * How important are unique time zone abbreviations?
721#
722# Here I tend to agree with the point (most recently made by Chris
723# Newman) that unique abbreviations should not be essential for proper
724# operation of software. We have other instances of ambiguity
725# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
726# Standard Time"), and they are not likely to go away any time soon.
727# In the old days, some software mistakenly relied on unique
728# abbreviations, but this is becoming less true with time, and I don't
729# think it's that important to cater to such software these days.
730#
731# On the other hand, there is another motivation for unambiguous
732# abbreviations: it cuts down on human confusion. This is
733# particularly true for Australia, where "EST" can mean one thing for
734# time T and a different thing for time T plus 1 second.
735#
736# * Does the relevant legislation indicate which abbreviations should be used?
737#
738# Here I tend to think that things are a mess, just as they are in
739# many other countries. We Americans are currently disagreeing about
740# which abbreviation to use for the newly legislated Chamorro Standard
741# Time, for example.
742#
743# Personally, I would prefer to use common practice; I would like to
744# refer to legislation only for examples of common practice, or as a
745# tiebreaker.
746#
747# * Do Australians more often use "Eastern Daylight Time" or "Eastern
748# Summer Time"? Do they typically prefix the time zone names with
749# the word "Australian"?
750#
751# My own impression is that both "Daylight Time" and "Summer Time" are
752# common and are widely understood, but that "Summer Time" is more
753# popular; and that the leading "A" is also common but is omitted more
754# often than not. I just used AltaVista advanced search and got the
755# following count of page hits:
756#
757# 1,103 "Eastern Summer Time" AND domain:au
758# 971 "Australian Eastern Summer Time" AND domain:au
759# 613 "Eastern Daylight Time" AND domain:au
760# 127 "Australian Eastern Daylight Time" AND domain:au
761#
762# Here "Summer" seems quite a bit more popular than "Daylight",
763# particularly when we know the time zone is Australian and not US,
764# say. The "Australian" prefix seems to be popular for Eastern Summer
765# Time, but unpopular for Eastern Daylight Time.
766#
767# For abbreviations, tools like AltaVista are less useful because of
768# ambiguity. Many hits are not really time zones, unfortunately, and
769# many hits denote US time zones and not Australian ones. But here
770# are the hit counts anyway:
771#
772# 161,304 "EST" and domain:au
773# 25,156 "EDT" and domain:au
774# 18,263 "AEST" and domain:au
775# 10,416 "AEDT" and domain:au
776#
777# 14,538 "CST" and domain:au
778# 5,728 "CDT" and domain:au
779# 176 "ACST" and domain:au
780# 29 "ACDT" and domain:au
781#
782# 7,539 "WST" and domain:au
783# 68 "AWST" and domain:au
784#
785# This data suggest that Australians tend to omit the "A" prefix in
786# practice. The situation for "ST" versus "DT" is less clear, given
787# the ambiguities involved.
788#
789# * How do Australians feel about the abbreviations in the tz database?
790#
791# If you just count Australians on this list, I count 2 in favor and 3
792# against. One of the "against" votes (David Keegel) counseled delay,
793# saying that both AEST/AEDT and EST/EST are widely used and
794# understood in Australia.
795
796# From Paul Eggert (1995-12-19):
797# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ.
798# Mark Prior writes that his newspaper
799# reports that NSW's fall 1995 change will occur at 2:00,
800# but Robert Elz says it's been 3:00 in Victoria since 1970
801# and perhaps the newspaper's `2:00' is referring to standard time.
802# For now we'll continue to assume 2:00s for changes since 1960.

933# From Rives McDow (2002-04-09):
934# The most interesting region I have found consists of three towns on the

936# Australia does not. The two states are one and a half hours apart. The
937# residents decided to forget about this nonsense of changing the clock so
938# much and set the local time 20 hours and 45 minutes from the
939# international date line, or right in the middle of the time of South
940# Australia and Western Australia....
941#
942# From Paul Eggert (2002-04-09):
943# This is confirmed by the section entitled

947# From Alex Livingston (2006-12-07):
948# ... it was just on four years ago that I drove along the Eyre Highway,
949# which passes through eastern Western Australia close to the southern
950# coast of the continent.
951#
952# I paid particular attention to the time kept there. There can be no
953# dispute that UTC+08:45 was considered "the time" from the border
954# village just inside the border with South Australia to as far west
955# as just east of Caiguna. There can also be no dispute that Eucla is
956# the largest population centre in this zone....
957#
958# Now that Western Australia is observing daylight saving, the
959# question arose whether this part of the state would follow suit. I
960# just called the border village and confirmed that indeed they have,

963# (2006-12-09):

1064# discussing his book "The Sun in the Church: Cathedrals as Solar
1065# Observatories"[1], and in particular the Shrine of Remembrance[2] located
1066# in Melbourne, Australia.
1067#
1068# Apparently the shrine's main purpose is a beam of sunlight which
1069# illuminates a special spot on the floor at the 11th hour of the 11th day
1070# of the 11th month (Remembrance Day) every year in memory of Australia's
1071# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
1072# you will indeed see the sunbeam illuminate the special spot at the
1073# expected time.
1074#
1075# However, that is only because of some special mirror contraption that had
1076# to be employed, since due to daylight savings time, the true solar time of
1077# the remembrance moment occurs one hour later (or earlier?). Perhaps
1078# someone with more information on this jury-rig can tell us more.

1183
1184# From James Lonergan, Secretary, Lord Howe Island Board (2000-01-27):
1185# Lord Howe Island summer time in 2000/2001 will commence on the same
1186# date as the rest of NSW (i.e. 2000-08-27). For your information the
1187# Lord Howe Island Board (controlling authority for the Island) is
1188# seeking the community's views on various options for summer time
1189# arrangements on the Island, e.g. advance clocks by 1 full hour
1190# instead of only 30 minutes. Dependant on the wishes of residents
1191# the Board may approach the NSW government to change the existing
1192# arrangements. The starting date for summer time on the Island will
1193# however always coincide with the rest of NSW.
1194
1195# From James Lonergan, Secretary, Lord Howe Island Board (2000-10-25):
1196# Lord Howe Island advances clocks by 30 minutes during DST in NSW and retards
1197# clocks by 30 minutes when DST finishes. Since DST was most recently
1198# introduced in NSW, the "changeover" time on the Island has been 02:00 as
1199# shown on clocks on LHI. I guess this means that for 30 minutes at the start
1200# of DST, LHI is actually 1 hour ahead of the rest of NSW.

1419# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
1420# How Tonga became `The Land where Time Begins'
1421# </a>:
1422
1423# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
1424# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
1425# standard time in 1940s, Tonga had the choice of subtracting from its
1426# local time to come on the same standard time as New Zealand or of
1427# advancing its time to maintain the differential of 13 degrees
1428# (approximately 50 minutes ahead of New Zealand time).
1429#
1430# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1431# Tungi, preferred to ensure Tonga's title as the land where time
1432# begins, the Legislative Assembly approved the latter change.
1433#
1434# But some of the older, more conservative members from the outer
1435# islands objected. "If at midnight on Dec. 31, we move ahead 40
1436# minutes, as your Royal Highness wishes, what becomes of the 40
1437# minutes we have lost?"
1438#
1439# The Crown Prince, presented an unanswerable argument: "Remember that
1440# on the World Day of Prayer, you would be the first people on Earth
1441# to say your prayers in the morning."
1442

1521# The International Date Line
1522
1523# From Gwillim Law (2000-01-03):
1524#
1525# The International Date Line is not defined by any international standard,
1526# convention, or treaty. Mapmakers are free to draw it as they please.
1527# Reputable mapmakers will simply ensure that every point of land appears on
1528# the correct side of the IDL, according to the date legally observed there.
1529#
1530# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1531# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1532# to the east side of the Phoenix and Line Islands), I suppose that most
1533# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
1534# has a rather arbitrary nature. The straight-line boundaries between Pacific
1535# island nations that are shown on many maps are based on an international
1536# convention, but are not legally binding national borders.... The date is
1537# governed by the IDL; therefore, even on the high seas, there may be some
1538# places as late as fourteen hours later than UTC. And, since the IDL is not
1539# an international standard, there are some places on the high seas where the

1542# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
1543# Before 1920, all ships kept local apparent time on the high seas by setting
1544# their clocks at night or at the morning sight so that, given the ship's
1545# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
1546# meridian (12 o'clock = local apparent noon). During 1917, at the
1547# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
1548# ships, both military and civilian, should adopt hourly standard time zones
1549# on the high seas. Whenever a ship was within the territorial waters of any
1550# nation it would use that nation's standard time. The captain was permitted
1551# to change his ship's clocks at a time of his choice following his ship's
1552# entry into another zone time--he often chose midnight. These zones were
1553# adopted by all major fleets between 1920 and 1925 but not by many
1554# independent merchant ships until World War II.

626
627# From Paul Eggert (2006-03-22):
628# A good source for time zone historical data outside the U.S. is
629# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
630# San Diego: ACS Publications, Inc. (2003).
631#
632# Gwillim Law writes that a good source
633# for recent time zone data is the International Air Transport
634# Association's Standard Schedules Information Manual (IATA SSIM),
635# published semiannually. Law sent in several helpful summaries
636# of the IATA's data after 1990.
637#
638# Except where otherwise noted, Shanks & Pottenger is the source for

640#
641# Another source occasionally used is Edward W. Whitman, World Time Differences,

683
684# From John Mackin (1991-03-06):
685# We in Australia have _never_ referred to DST as `daylight' time.
686# It is called `summer' time. Now by a happy coincidence, `summer'
687# and `standard' happen to start with the same letter; hence, the
688# abbreviation does _not_ change...
689# The legislation does not actually define abbreviations, at least
690# in this State, but the abbreviation is just commonly taken to be the
691# initials of the phrase, and the legislation here uniformly uses
692# the phrase `summer time' and does not use the phrase `daylight
693# time'.
694# Announcers on the Commonwealth radio network, the ABC (for Australian
695# Broadcasting Commission), use the phrases `Eastern Standard Time'
696# or `Eastern Summer Time'. (Note, though, that as I say in the
697# current australasia file, there is really no such thing.) Announcers
698# on its overseas service, Radio Australia, use the same phrases
699# prefixed by the word `Australian' when referring to local times;
700# time announcements on that service, naturally enough, are made in UTC.
701
702# From Arthur David Olson (1992-03-08):
703# Given the above, what's chosen for year-round use is:

705# WST for any place operating at a GMTOFF of 8:00
706# EST for any place operating at a GMTOFF of 10:00
707
708# From Chuck Soper (2006-06-01):
709# I recently found this Australian government web page on time zones:
710# <http://www.australia.gov.au/about-australia-13time>
711# And this government web page lists time zone names and abbreviations:
712# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml>
713
714# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
715# versus "AEST" etc.:
716#
717# I see the following points of dispute:
718#
719# * How important are unique time zone abbreviations?
720#
721# Here I tend to agree with the point (most recently made by Chris
722# Newman) that unique abbreviations should not be essential for proper
723# operation of software. We have other instances of ambiguity
724# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
725# Standard Time"), and they are not likely to go away any time soon.
726# In the old days, some software mistakenly relied on unique
727# abbreviations, but this is becoming less true with time, and I don't
728# think it's that important to cater to such software these days.
729#
730# On the other hand, there is another motivation for unambiguous
731# abbreviations: it cuts down on human confusion. This is
732# particularly true for Australia, where "EST" can mean one thing for
733# time T and a different thing for time T plus 1 second.
734#
735# * Does the relevant legislation indicate which abbreviations should be used?
736#
737# Here I tend to think that things are a mess, just as they are in
738# many other countries. We Americans are currently disagreeing about
739# which abbreviation to use for the newly legislated Chamorro Standard
740# Time, for example.
741#
742# Personally, I would prefer to use common practice; I would like to
743# refer to legislation only for examples of common practice, or as a
744# tiebreaker.
745#
746# * Do Australians more often use "Eastern Daylight Time" or "Eastern
747# Summer Time"? Do they typically prefix the time zone names with
748# the word "Australian"?
749#
750# My own impression is that both "Daylight Time" and "Summer Time" are
751# common and are widely understood, but that "Summer Time" is more
752# popular; and that the leading "A" is also common but is omitted more
753# often than not. I just used AltaVista advanced search and got the
754# following count of page hits:
755#
756# 1,103 "Eastern Summer Time" AND domain:au
757# 971 "Australian Eastern Summer Time" AND domain:au
758# 613 "Eastern Daylight Time" AND domain:au
759# 127 "Australian Eastern Daylight Time" AND domain:au
760#
761# Here "Summer" seems quite a bit more popular than "Daylight",
762# particularly when we know the time zone is Australian and not US,
763# say. The "Australian" prefix seems to be popular for Eastern Summer
764# Time, but unpopular for Eastern Daylight Time.
765#
766# For abbreviations, tools like AltaVista are less useful because of
767# ambiguity. Many hits are not really time zones, unfortunately, and
768# many hits denote US time zones and not Australian ones. But here
769# are the hit counts anyway:
770#
771# 161,304 "EST" and domain:au
772# 25,156 "EDT" and domain:au
773# 18,263 "AEST" and domain:au
774# 10,416 "AEDT" and domain:au
775#
776# 14,538 "CST" and domain:au
777# 5,728 "CDT" and domain:au
778# 176 "ACST" and domain:au
779# 29 "ACDT" and domain:au
780#
781# 7,539 "WST" and domain:au
782# 68 "AWST" and domain:au
783#
784# This data suggest that Australians tend to omit the "A" prefix in
785# practice. The situation for "ST" versus "DT" is less clear, given
786# the ambiguities involved.
787#
788# * How do Australians feel about the abbreviations in the tz database?
789#
790# If you just count Australians on this list, I count 2 in favor and 3
791# against. One of the "against" votes (David Keegel) counseled delay,
792# saying that both AEST/AEDT and EST/EST are widely used and
793# understood in Australia.
794
795# From Paul Eggert (1995-12-19):
796# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ.
797# Mark Prior writes that his newspaper
798# reports that NSW's fall 1995 change will occur at 2:00,
799# but Robert Elz says it's been 3:00 in Victoria since 1970
800# and perhaps the newspaper's `2:00' is referring to standard time.
801# For now we'll continue to assume 2:00s for changes since 1960.

933# The most interesting region I have found consists of three towns on the
934# southern coast.... South Australia observes daylight saving time; Western
935# Australia does not. The two states are one and a half hours apart. The
936# residents decided to forget about this nonsense of changing the clock so
937# much and set the local time 20 hours and 45 minutes from the
938# international date line, or right in the middle of the time of South
939# Australia and Western Australia....

948# which passes through eastern Western Australia close to the southern
949# coast of the continent.
950#
951# I paid particular attention to the time kept there. There can be no
952# dispute that UTC+08:45 was considered "the time" from the border
953# village just inside the border with South Australia to as far west
954# as just east of Caiguna. There can also be no dispute that Eucla is
955# the largest population centre in this zone....
956#
957# Now that Western Australia is observing daylight saving, the
958# question arose whether this part of the state would follow suit. I
959# just called the border village and confirmed that indeed they have,

962# (2006-12-09):

1061# On KQED's "City Arts and Lectures" program last night I heard an

1063# discussing his book "The Sun in the Church: Cathedrals as Solar
1064# Observatories"[1], and in particular the Shrine of Remembrance[2] located
1065# in Melbourne, Australia.
1066#
1067# Apparently the shrine's main purpose is a beam of sunlight which
1068# illuminates a special spot on the floor at the 11th hour of the 11th day
1069# of the 11th month (Remembrance Day) every year in memory of Australia's
1070# fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time,
1071# you will indeed see the sunbeam illuminate the special spot at the
1072# expected time.
1073#
1074# However, that is only because of some special mirror contraption that had
1075# to be employed, since due to daylight savings time, the true solar time of
1076# the remembrance moment occurs one hour later (or earlier?). Perhaps
1077# someone with more information on this jury-rig can tell us more.

1195# Lord Howe Island advances clocks by 30 minutes during DST in NSW and retards

1418# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm">
1419# How Tonga became `The Land where Time Begins'
1420# </a>:
1421
1422# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
1423# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
1424# standard time in 1940s, Tonga had the choice of subtracting from its
1425# local time to come on the same standard time as New Zealand or of
1426# advancing its time to maintain the differential of 13 degrees
1427# (approximately 50 minutes ahead of New Zealand time).
1428#
1429# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
1430# Tungi, preferred to ensure Tonga's title as the land where time
1431# begins, the Legislative Assembly approved the latter change.
1432#
1433# But some of the older, more conservative members from the outer
1434# islands objected. "If at midnight on Dec. 31, we move ahead 40
1435# minutes, as your Royal Highness wishes, what becomes of the 40
1436# minutes we have lost?"
1437#
1438# The Crown Prince, presented an unanswerable argument: "Remember that
1439# on the World Day of Prayer, you would be the first people on Earth
1440# to say your prayers in the morning."
1441
1442# From Paul Eggert (2006-03-22):

1520# The International Date Line
1521
1522# From Gwillim Law (2000-01-03):
1523#
1524# The International Date Line is not defined by any international standard,
1525# convention, or treaty. Mapmakers are free to draw it as they please.
1526# Reputable mapmakers will simply ensure that every point of land appears on
1527# the correct side of the IDL, according to the date legally observed there.
1528#
1529# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
1530# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
1531# to the east side of the Phoenix and Line Islands), I suppose that most
1532# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
1533# has a rather arbitrary nature. The straight-line boundaries between Pacific
1534# island nations that are shown on many maps are based on an international
1535# convention, but are not legally binding national borders.... The date is
1536# governed by the IDL; therefore, even on the high seas, there may be some
1537# places as late as fourteen hours later than UTC. And, since the IDL is not
1538# an international standard, there are some places on the high seas where the
1539# correct date is ambiguous.
1540
1541# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31):
1542# Before 1920, all ships kept local apparent time on the high seas by setting
1543# their clocks at night or at the morning sight so that, given the ship's
1544# speed and direction, it would be 12 o'clock when the Sun crossed the ship's
1545# meridian (12 o'clock = local apparent noon). During 1917, at the
1546# Anglo-French Conference on Time-keeping at Sea, it was recommended that all
1547# ships, both military and civilian, should adopt hourly standard time zones
1548# on the high seas. Whenever a ship was within the territorial waters of any
1549# nation it would use that nation's standard time. The captain was permitted
1550# to change his ship's clocks at a time of his choice following his ship's
1551# entry into another zone time--he often chose midnight. These zones were
1552# adopted by all major fleets between 1920 and 1925 but not by many
1553# independent merchant ships until World War II.
