We have other instances of ambiguity 889# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 890# Standard Time"), and they are not likely to go away any time soon. 891# In the old days, some software mistakenly relied on unique 892# abbreviations, but this is becoming less true with time, and I don't 893# think it's that important to cater to such software these days. 894# 895# On the other hand, there is another motivation for unambiguous 896# abbreviations: it cuts down on human confusion. This is 897# particularly true for Australia, where "EST" can mean one thing for 898# time T and a different thing for time T plus 1 second. 899# 900# * Does the relevant legislation indicate which abbreviations should be used? 901# 902# Here I tend to think that things are a mess, just as they are in 903# many other countries. We Americans are currently disagreeing about 904# which abbreviation to use for the newly legislated Chamorro Standard 905# Time, for example. 906# 907# Personally, I would prefer to use common practice; I would like to 908# refer to legislation only for examples of common practice, or as a 909# tiebreaker. 910# 911# * Do Australians more often use "Eastern Daylight Time" or "Eastern 912# Summer Time"? Do they typically prefix the time zone names with 913# the word "Australian"? 914# 915# My own impression is that both "Daylight Time" and "Summer Time" are 916# common and are widely understood, but that "Summer Time" is more 917# popular; and that the leading "A" is also common but is omitted more 918# often than not. I just used AltaVista advanced search and got the 919# following count of page hits: 920# 921# 1,103 "Eastern Summer Time" AND domain:au 922# 971 "Australian Eastern Summer Time" AND domain:au 923# 613 "Eastern Daylight Time" AND domain:au 924# 127 "Australian Eastern Daylight Time" AND domain:au 925# 926# Here "Summer" seems quite a bit more popular than "Daylight", 927# particularly when we know the time zone is Australian and not US, 928# say. The "Australian" prefix seems to be popular for Eastern Summer 929# Time, but unpopular for Eastern Daylight Time. 930# 931# For abbreviations, tools like AltaVista are less useful because of 932# ambiguity. Many hits are not really time zones, unfortunately, and 933# many hits denote US time zones and not Australian ones. But here 934# are the hit counts anyway: 935# 936# 161,304 "EST" and domain:au 937# 25,156 "EDT" and domain:au 938# 18,263 "AEST" and domain:au 939# 10,416 "AEDT" and domain:au 940# 941# 14,538 "CST" and domain:au 942# 5,728 "CDT" and domain:au 943# 176 "ACST" and domain:au 944# 29 "ACDT" and domain:au 945# 946# 7,539 "WST" and domain:au 947# 68 "AWST" and domain:au 948# 949# This data suggest that Australians tend to omit the "A" prefix in 950# practice. The situation for "ST" versus "DT" is less clear, given 951# the ambiguities involved. 952# 953# * How do Australians feel about the abbreviations in the tz database? 954# 955# If you just count Australians on this list, I count 2 in favor and 3 956# against. One of the "against" votes (David Keegel) counseled delay, 957# saying that both AEST/AEDT and EST/EST are widely used and 958# understood in Australia. 959 960# From Paul Eggert (1995-12-19): 961# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 962# Mark Prior writes that his newspaper 963# reports that NSW's fall 1995 change will occur at 2:00, 964# but Robert Elz says it's been 3:00 in Victoria since 1970 965# and perhaps the newspaper's `2:00' is referring to standard time. 966# For now we'll continue to assume 2:00s for changes since 1960. 967 968# From Eric Ulevik (1998-01-05): 969# 970# Here are some URLs to Australian time legislation.

Even that line 1698# has a rather arbitrary nature. The straight-line boundaries between Pacific 1699# island nations that are shown on many maps are based on an international 1700# convention, but are not legally binding national borders.... The date is 1701# governed by the IDL; therefore, even on the high seas, there may be some 1702# places as late as fourteen hours later than UTC.

During 1917, at the 1711# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1712# ships, both military and civilian, should adopt hourly standard time zones 1713# on the high seas.

Now by a happy coincidence, `summer' 869# and `standard' happen to start with the same letter; hence, the 870# abbreviation does _not_ change... 871# The legislation does not actually define abbreviations, at least 872# in this State, but the abbreviation is just commonly taken to be the 873# initials of the phrase, and the legislation here uniformly uses 874# the phrase `summer time' and does not use the phrase `daylight 875# time'. 876# Announcers on the Commonwealth radio network, the ABC (for Australian 877# Broadcasting Commission), use the phrases `Eastern Standard Time' 878# or `Eastern Summer Time'. (Note, though, that as I say in the 879# current australasia file, there is really no such thing.) Announcers 880# on its overseas service, Radio Australia, use the same phrases 881# prefixed by the word `Australian' when referring to local times; 882# time announcements on that service, naturally enough, are made in UTC. 883 884# From Arthur David Olson (1992-03-08): 885# Given the above, what's chosen for year-round use is: 886# CST for any place operating at a GMTOFF of 9:30 887# WST for any place operating at a GMTOFF of 8:00 888# EST for any place operating at a GMTOFF of 10:00 889 890# From Chuck Soper (2006-06-01): 891# I recently found this Australian government web page on time zones: 892# <http://www.australia.gov.au/about-australia-13time> 893# And this government web page lists time zone names and abbreviations: 894# <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> 895 896# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" 897# versus "AEST" etc.: 898# 899# I see the following points of dispute: 900# 901# * How important are unique time zone abbreviations? 902# 903# Here I tend to agree with the point (most recently made by Chris 904# Newman) that unique abbreviations should not be essential for proper 905# operation of software. We have other instances of ambiguity 906# (e.g. "IST" denoting both "Israel Standard Time" and "Indian 907# Standard Time"), and they are not likely to go away any time soon. 908# In the old days, some software mistakenly relied on unique 909# abbreviations, but this is becoming less true with time, and I don't 910# think it's that important to cater to such software these days. 911# 912# On the other hand, there is another motivation for unambiguous 913# abbreviations: it cuts down on human confusion. This is 914# particularly true for Australia, where "EST" can mean one thing for 915# time T and a different thing for time T plus 1 second. 916# 917# * Does the relevant legislation indicate which abbreviations should be used? 918# 919# Here I tend to think that things are a mess, just as they are in 920# many other countries. We Americans are currently disagreeing about 921# which abbreviation to use for the newly legislated Chamorro Standard 922# Time, for example. 923# 924# Personally, I would prefer to use common practice; I would like to 925# refer to legislation only for examples of common practice, or as a 926# tiebreaker. 927# 928# * Do Australians more often use "Eastern Daylight Time" or "Eastern 929# Summer Time"? Do they typically prefix the time zone names with 930# the word "Australian"? 931# 932# My own impression is that both "Daylight Time" and "Summer Time" are 933# common and are widely understood, but that "Summer Time" is more 934# popular; and that the leading "A" is also common but is omitted more 935# often than not. I just used AltaVista advanced search and got the 936# following count of page hits: 937# 938# 1,103 "Eastern Summer Time" AND domain:au 939# 971 "Australian Eastern Summer Time" AND domain:au 940# 613 "Eastern Daylight Time" AND domain:au 941# 127 "Australian Eastern Daylight Time" AND domain:au 942# 943# Here "Summer" seems quite a bit more popular than "Daylight", 944# particularly when we know the time zone is Australian and not US, 945# say. The "Australian" prefix seems to be popular for Eastern Summer 946# Time, but unpopular for Eastern Daylight Time. 947# 948# For abbreviations, tools like AltaVista are less useful because of 949# ambiguity. Many hits are not really time zones, unfortunately, and 950# many hits denote US time zones and not Australian ones. But here 951# are the hit counts anyway: 952# 953# 161,304 "EST" and domain:au 954# 25,156 "EDT" and domain:au 955# 18,263 "AEST" and domain:au 956# 10,416 "AEDT" and domain:au 957# 958# 14,538 "CST" and domain:au 959# 5,728 "CDT" and domain:au 960# 176 "ACST" and domain:au 961# 29 "ACDT" and domain:au 962# 963# 7,539 "WST" and domain:au 964# 68 "AWST" and domain:au 965# 966# This data suggest that Australians tend to omit the "A" prefix in 967# practice. The situation for "ST" versus "DT" is less clear, given 968# the ambiguities involved. 969# 970# * How do Australians feel about the abbreviations in the tz database? 971# 972# If you just count Australians on this list, I count 2 in favor and 3 973# against. One of the "against" votes (David Keegel) counseled delay, 974# saying that both AEST/AEDT and EST/EST are widely used and 975# understood in Australia. 976 977# From Paul Eggert (1995-12-19): 978# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. 979# Mark Prior writes that his newspaper 980# reports that NSW's fall 1995 change will occur at 2:00, 981# but Robert Elz says it's been 3:00 in Victoria since 1970 982# and perhaps the newspaper's `2:00' is referring to standard time. 983# For now we'll continue to assume 2:00s for changes since 1960. 984 985# From Eric Ulevik (1998-01-05): 986# 987# Here are some URLs to Australian time legislation.

Underwood, author of the bill that became law, 1521# wrote in a press release (2000-12-27) that he will seek the use of "ChST". 1522 1523 1524# Micronesia 1525 1526# Alan Eugene Davis writes (1996-03-16), 1527# ``I am certain, having lived there for the past decade, that "Truk" 1528# (now properly known as Chuuk) ... is in the time zone GMT+10.'' 1529# 1530# Shanks & Pottenger write that Truk switched from UTC+10 to UTC+11 1531# on 1978-10-01; ignore this for now. 1532 1533# From Paul Eggert (1999-10-29): 1534# The Federated States of Micronesia Visitors Board writes in 1535# <a href="http://www.fsmgov.org/info/clocks.html"> 1536# The Federated States of Micronesia - Visitor Information 1537# </a> (1999-01-26) 1538# that Truk and Yap are UTC+10, and Ponape and Kosrae are UTC+11. 1539# We don't know when Kosrae switched from UTC+12; assume January 1 for now. 1540 1541 1542# Midway 1543 1544# From Charles T O'Connor, KMTH DJ (1956), 1545# quoted in the KTMH section of the Radio Heritage Collection 1546# <http://radiodx.com/spdxr/KMTH.htm> (2002-12-31): 1547# For the past two months we've been on what is known as Daylight 1548# Saving Time. This time has put us on air at 5am in the morning, 1549# your time down there in New Zealand. Starting September 2, 1956 1550# we'll again go back to Standard Time. This'll mean that we'll go to 1551# air at 6am your time. 1552# 1553# From Paul Eggert (2003-03-23): 1554# We don't know the date of that quote, but we'll guess they 1555# started DST on June 3. Possibly DST was observed other years 1556# in Midway, but we have no record of it. 1557 1558 1559# Pitcairn 1560 1561# From Rives McDow (1999-11-08): 1562# A Proclamation was signed by the Governor of Pitcairn on the 27th March 1998 1563# with regard to Pitcairn Standard Time. The Proclamation is as follows. 1564# 1565# The local time for general purposes in the Islands shall be 1566# Co-ordinated Universal time minus 8 hours and shall be known 1567# as Pitcairn Standard Time. 1568# 1569# ... I have also seen Pitcairn listed as UTC minus 9 hours in several 1570# references, and can only assume that this was an error in interpretation 1571# somehow in light of this proclamation. 1572 1573# From Rives McDow (1999-11-09): 1574# The Proclamation regarding Pitcairn time came into effect on 27 April 1998 1575# ... at midnight. 1576 1577# From Howie Phelps (1999-11-10), who talked to a Pitcairner via shortwave: 1578# Betty Christian told me yesterday that their local time is the same as 1579# Pacific Standard Time. They used to be 1/2 hour different from us here in 1580# Sacramento but it was changed a couple of years ago. 1581 1582 1583# Samoa 1584 1585# Howse writes (p 153, citing p 10 of the 1883-11-18 New York Herald) 1586# that in 1879 the King of Samoa decided to change 1587# ``the date in his kingdom from the Antipodean to the American system, 1588# ordaining -- by a masterpiece of diplomatic flattery -- that 1589# the Fourth of July should be celebrated twice in that year.'' 1590 1591 1592# Tonga 1593 1594# From Paul Eggert (1996-01-22): 1595# Today's _Wall Street Journal_ (p 1) reports that ``Tonga has been plotting 1596# to sneak ahead of [New Zealanders] by introducing daylight-saving time.'' 1597# Since Kiribati has moved the Date Line it's not clear what Tonga will do. 1598 1599# Don Mundell writes in the 1997-02-20 Tonga Chronicle 1600# <a href="http://www.tongatapu.net.to/tonga/homeland/timebegins.htm"> 1601# How Tonga became `The Land where Time Begins' 1602# </a>: 1603 1604# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST 1605# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its 1606# standard time in 1940s, Tonga had the choice of subtracting from its 1607# local time to come on the same standard time as New Zealand or of 1608# advancing its time to maintain the differential of 13 degrees 1609# (approximately 50 minutes ahead of New Zealand time). 1610# 1611# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince 1612# Tungi, preferred to ensure Tonga's title as the land where time 1613# begins, the Legislative Assembly approved the latter change. 1614# 1615# But some of the older, more conservative members from the outer 1616# islands objected. "If at midnight on Dec. 31, we move ahead 40 1617# minutes, as your Royal Highness wishes, what becomes of the 40 1618# minutes we have lost?" 1619# 1620# The Crown Prince, presented an unanswerable argument: "Remember that 1621# on the World Day of Prayer, you would be the first people on Earth 1622# to say your prayers in the morning." 1623 1624# From Paul Eggert (2006-03-22): 1625# Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell. 1626 1627# From Eric Ulevik (1999-05-03): 1628# Tonga's director of tourism, who is also secretary of the National Millenium 1629# Committee, has a plan to get Tonga back in front. 1630# He has proposed a one-off move to tropical daylight saving for Tonga from 1631# October to March, which has won approval in principle from the Tongan 1632# Government. 1633 1634# From Steffen Thorsen (1999-09-09): 1635# * Tonga will introduce DST in November 1636# 1637# I was given this link by John Letts: 1638# <a href="http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm"> 1639# http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm 1640# </a> 1641# 1642# I have not been able to find exact dates for the transition in November 1643# yet. By reading this article it seems like Fiji will be 14 hours ahead 1644# of UTC as well, but as far as I know Fiji will only be 13 hours ahead 1645# (12 + 1 hour DST). 1646 1647# From Arthur David Olson (1999-09-20): 1648# According to <a href="http://www.tongaonline.com/news/sept1799.html"> 1649# http://www.tongaonline.com/news/sept1799.html 1650# </a>: 1651# "Daylight Savings Time will take effect on Oct. 2 through April 15, 2000 1652# and annually thereafter from the first Saturday in October through the 1653# third Saturday of April. Under the system approved by Privy Council on 1654# Sept. 10, clocks must be turned ahead one hour on the opening day and 1655# set back an hour on the closing date." 1656# Alas, no indication of the time of day. 1657 1658# From Rives McDow (1999-10-06): 1659# Tonga started its Daylight Saving on Saturday morning October 2nd at 0200am. 1660# Daylight Saving ends on April 16 at 0300am which is Sunday morning. 1661 1662# From Steffen Thorsen (2000-10-31): 1663# Back in March I found a notice on the website http://www.tongaonline.com 1664# that Tonga changed back to standard time one month early, on March 19 1665# instead of the original reported date April 16. Unfortunately, the article 1666# is no longer available on the site, and I did not make a copy of the 1667# text, and I have forgotten to report it here. 1668# (Original URL was: http://www.tongaonline.com/news/march162000.htm ) 1669 1670# From Rives McDow (2000-12-01): 1671# Tonga is observing DST as of 2000-11-04 and will stop on 2001-01-27. 1672 1673# From Sione Moala-Mafi (2001-09-20) via Rives McDow: 1674# At 2:00am on the first Sunday of November, the standard time in the Kingdom 1675# shall be moved forward by one hour to 3:00am. At 2:00am on the last Sunday 1676# of January the standard time in the Kingdom shall be moved backward by one 1677# hour to 1:00am. 1678 1679# From Pulu 'Anau (2002-11-05): 1680# The law was for 3 years, supposedly to get renewed.

The time was all the 1689# more confusing at that point, because we had crossed the 1690# International Date Line, thus getting two Sundays. Furthermore, we 1691# discovered that Wake Island had two hours of daylight saving time 1692# making calculation of time in Washington difficult if not almost 1693# impossible. 1694# 1695# http://www.trumanlibrary.org/wake/meeting.htm 1696 1697# From Paul Eggert (2003-03-23): 1698# We have no other report of DST in Wake Island, so omit this info for now. 1699 1700############################################################################### 1701 1702# The International Date Line 1703 1704# From Gwillim Law (2000-01-03): 1705# 1706# The International Date Line is not defined by any international standard, 1707# convention, or treaty. Mapmakers are free to draw it as they please. 1708# Reputable mapmakers will simply ensure that every point of land appears on 1709# the correct side of the IDL, according to the date legally observed there. 1710# 1711# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and 1712# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL 1713# to the east side of the Phoenix and Line Islands), I suppose that most 1714# mapmakers redrew the IDL following the boundary of Kiribati. Even that line 1715# has a rather arbitrary nature. The straight-line boundaries between Pacific 1716# island nations that are shown on many maps are based on an international 1717# convention, but are not legally binding national borders.... The date is 1718# governed by the IDL; therefore, even on the high seas, there may be some 1719# places as late as fourteen hours later than UTC. And, since the IDL is not 1720# an international standard, there are some places on the high seas where the 1721# correct date is ambiguous. 1722 1723# From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): 1724# Before 1920, all ships kept local apparent time on the high seas by setting 1725# their clocks at night or at the morning sight so that, given the ship's 1726# speed and direction, it would be 12 o'clock when the Sun crossed the ship's 1727# meridian (12 o'clock = local apparent noon). During 1917, at the 1728# Anglo-French Conference on Time-keeping at Sea, it was recommended that all 1729# ships, both military and civilian, should adopt hourly standard time zones 1730# on the high seas. Whenever a ship was within the territorial waters of any 1731# nation it would use that nation's standard time. The captain was permitted 1732# to change his ship's clocks at a time of his choice following his ship's 1733# entry into another zone time--he often chose midnight. These zones were 1734# adopted by all major fleets between 1920 and 1925 but not by many 1735# independent merchant ships until World War II. 1736 1737# From Paul Eggert, using references suggested by Oscar van Vlijmen 1738# (2005-03-20): 1739# 1740# The American Practical Navigator (2002) 1741# <http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187> 1742# talks only about the 180-degree meridian with respect to ships in 1743# international waters; it ignores the international date line.
