| 800 | # </a> covers New South Wales in particular. |
| 801 | |
| 802 | # From John Mackin (1991-03-06): |
| 803 | # We in Australia have _never_ referred to DST as `daylight' time. |
| 804 | # It is called `summer' time. Now by a happy coincidence, `summer' |
| 805 | # and `standard' happen to start with the same letter; hence, the |
| 806 | # abbreviation does _not_ change... |
| 807 | # The legislation does not actually define abbreviations, at least |
| 808 | # in this State, but the abbreviation is just commonly taken to be the |
| 809 | # initials of the phrase, and the legislation here uniformly uses |
| 810 | # the phrase `summer time' and does not use the phrase `daylight |
| 811 | # time'. |
| 812 | # Announcers on the Commonwealth radio network, the ABC (for Australian |
| 813 | # Broadcasting Commission), use the phrases `Eastern Standard Time' |
| 814 | # or `Eastern Summer Time'. (Note, though, that as I say in the |
| 815 | # current australasia file, there is really no such thing.) Announcers |
| 816 | # on its overseas service, Radio Australia, use the same phrases |
| 817 | # prefixed by the word `Australian' when referring to local times; |
| 818 | # time announcements on that service, naturally enough, are made in UTC. |
| 819 | |
| 820 | # From Arthur David Olson (1992-03-08): |
| 821 | # Given the above, what's chosen for year-round use is: |
| 822 | # CST for any place operating at a GMTOFF of 9:30 |
| 823 | # WST for any place operating at a GMTOFF of 8:00 |
| 824 | # EST for any place operating at a GMTOFF of 10:00 |
| 825 | |
| 826 | # From Chuck Soper (2006-06-01): |
| 827 | # I recently found this Australian government web page on time zones: |
| 828 | # <http://www.australia.gov.au/about-australia-13time> |
| 829 | # And this government web page lists time zone names and abbreviations: |
| 830 | # <http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml> |
| 831 | |
| 832 | # From Paul Eggert (2001-04-05), summarizing a long discussion about "EST" |
| 833 | # versus "AEST" etc.: |
| 834 | # |
| 835 | # I see the following points of dispute: |
| 836 | # |
| 837 | # * How important are unique time zone abbreviations? |
| 838 | # |
| 839 | # Here I tend to agree with the point (most recently made by Chris |
| 840 | # Newman) that unique abbreviations should not be essential for proper |
| 841 | # operation of software. We have other instances of ambiguity |
| 842 | # (e.g. "IST" denoting both "Israel Standard Time" and "Indian |
| 843 | # Standard Time"), and they are not likely to go away any time soon. |
| 844 | # In the old days, some software mistakenly relied on unique |
| 845 | # abbreviations, but this is becoming less true with time, and I don't |
| 846 | # think it's that important to cater to such software these days. |
| 847 | # |
| 848 | # On the other hand, there is another motivation for unambiguous |
| 849 | # abbreviations: it cuts down on human confusion. This is |
| 850 | # particularly true for Australia, where "EST" can mean one thing for |
| 851 | # time T and a different thing for time T plus 1 second. |
| 852 | # |
| 853 | # * Does the relevant legislation indicate which abbreviations should be used? |
| 854 | # |
| 855 | # Here I tend to think that things are a mess, just as they are in |
| 856 | # many other countries. We Americans are currently disagreeing about |
| 857 | # which abbreviation to use for the newly legislated Chamorro Standard |
| 858 | # Time, for example. |
| 859 | # |
| 860 | # Personally, I would prefer to use common practice; I would like to |
| 861 | # refer to legislation only for examples of common practice, or as a |
| 862 | # tiebreaker. |
| 863 | # |
| 864 | # * Do Australians more often use "Eastern Daylight Time" or "Eastern |
| 865 | # Summer Time"? Do they typically prefix the time zone names with |
| 866 | # the word "Australian"? |
| 867 | # |
| 868 | # My own impression is that both "Daylight Time" and "Summer Time" are |
| 869 | # common and are widely understood, but that "Summer Time" is more |
| 870 | # popular; and that the leading "A" is also common but is omitted more |
| 871 | # often than not. I just used AltaVista advanced search and got the |
| 872 | # following count of page hits: |
| 873 | # |
| 874 | # 1,103 "Eastern Summer Time" AND domain:au |
| 875 | # 971 "Australian Eastern Summer Time" AND domain:au |
| 876 | # 613 "Eastern Daylight Time" AND domain:au |
| 877 | # 127 "Australian Eastern Daylight Time" AND domain:au |
| 878 | # |
| 879 | # Here "Summer" seems quite a bit more popular than "Daylight", |
| 880 | # particularly when we know the time zone is Australian and not US, |
| 881 | # say. The "Australian" prefix seems to be popular for Eastern Summer |
| 882 | # Time, but unpopular for Eastern Daylight Time. |
| 883 | # |
| 884 | # For abbreviations, tools like AltaVista are less useful because of |
| 885 | # ambiguity. Many hits are not really time zones, unfortunately, and |
| 886 | # many hits denote US time zones and not Australian ones. But here |
| 887 | # are the hit counts anyway: |
| 888 | # |
| 889 | # 161,304 "EST" and domain:au |
| 890 | # 25,156 "EDT" and domain:au |
| 891 | # 18,263 "AEST" and domain:au |
| 892 | # 10,416 "AEDT" and domain:au |
| 893 | # |
| 894 | # 14,538 "CST" and domain:au |
| 895 | # 5,728 "CDT" and domain:au |
| 896 | # 176 "ACST" and domain:au |
| 897 | # 29 "ACDT" and domain:au |
| 898 | # |
| 899 | # 7,539 "WST" and domain:au |
| 900 | # 68 "AWST" and domain:au |
| 901 | # |
| 902 | # This data suggest that Australians tend to omit the "A" prefix in |
| 903 | # practice. The situation for "ST" versus "DT" is less clear, given |
| 904 | # the ambiguities involved. |
| 905 | # |
| 906 | # * How do Australians feel about the abbreviations in the tz database? |
| 907 | # |
| 908 | # If you just count Australians on this list, I count 2 in favor and 3 |
| 909 | # against. One of the "against" votes (David Keegel) counseled delay, |
| 910 | # saying that both AEST/AEDT and EST/EST are widely used and |
| 911 | # understood in Australia. |
| 912 | |
| 913 | # From Paul Eggert (1995-12-19): |

| 915 | # Mark Prior writes that his newspaper |
| 916 | # reports that NSW's fall 1995 change will occur at 2:00, |
| 917 | # but Robert Elz says it's been 3:00 in Victoria since 1970 |

| 1053 | # Australia does not. The two states are one and a half hours apart. The |

| 1066 | # which passes through eastern Western Australia close to the southern |
| 1067 | # coast of the continent. |
| 1068 | # |
| 1069 | # I paid particular attention to the time kept there. There can be no |
| 1070 | # dispute that UTC+08:45 was considered "the time" from the border |
| 1071 | # village just inside the border with South Australia to as far west |
| 1072 | # as just east of Caiguna. There can also be no dispute that Eucla is |
| 1073 | # the largest population centre in this zone.... |

| 1075 | # Now that Western Australia is observing daylight saving, the |
| 1076 | # question arose whether this part of the state would follow suit. I |
| 1077 | # just called the border village and confirmed that indeed they have, |

| 1079 | # |
| 1080 | # (2006-12-09): |
| 1081 | # I personally doubt that either experimentation with daylight saving |

| 1179 | # On KQED's "City Arts and Lectures" program last night I heard an |
| 1180 | # interesting story about daylight savings time. Dr. John Heilbron was |
| 1181 | # discussing his book "The Sun in the Church: Cathedrals as Solar |
| 1182 | # Observatories"[1], and in particular the Shrine of Remembrance[2] located |
| 1183 | # in Melbourne, Australia. |
| 1184 | # |
| 1185 | # Apparently the shrine's main purpose is a beam of sunlight which |
| 1186 | # illuminates a special spot on the floor at the 11th hour of the 11th day |
| 1187 | # of the 11th month (Remembrance Day) every year in memory of Australia's |
| 1188 | # fallen WWI soldiers. And if you go there on Nov. 11, at 11am local time, |
| 1189 | # you will indeed see the sunbeam illuminate the special spot at the |
| 1190 | # expected time. |
| 1191 | # |
| 1192 | # However, that is only because of some special mirror contraption that had |
| 1193 | # to be employed, since due to daylight savings time, the true solar time of |
| 1194 | # the remembrance moment occurs one hour later (or earlier?). Perhaps |

| 1539 | |
| 1540 | # Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST |
| 1541 | # 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its |
| 1542 | # standard time in 1940s, Tonga had the choice of subtracting from its |
| 1543 | # local time to come on the same standard time as New Zealand or of |
| 1544 | # advancing its time to maintain the differential of 13 degrees |
| 1545 | # (approximately 50 minutes ahead of New Zealand time). |
| 1546 | # |
| 1547 | # Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince |
| 1548 | # Tungi, preferred to ensure Tonga's title as the land where time |
| 1549 | # begins, the Legislative Assembly approved the latter change. |
| 1550 | # |
| 1551 | # But some of the older, more conservative members from the outer |
| 1552 | # islands objected. "If at midnight on Dec. 31, we move ahead 40 |
| 1553 | # minutes, as your Royal Highness wishes, what becomes of the 40 |
| 1554 | # minutes we have lost?" |
| 1555 | # |
| 1556 | # The Crown Prince, presented an unanswerable argument: "Remember that |
| 1557 | # on the World Day of Prayer, you would be the first people on Earth |
| 1558 | # to say your prayers in the morning." |

| 1639 | |
| 1640 | # From Gwillim Law (2000-01-03): |
| 1641 | # |
| 1642 | # The International Date Line is not defined by any international standard, |
| 1643 | # convention, or treaty. Mapmakers are free to draw it as they please. |
| 1644 | # Reputable mapmakers will simply ensure that every point of land appears on |
| 1645 | # the correct side of the IDL, according to the date legally observed there. |
| 1646 | # |
| 1647 | # When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and |
| 1648 | # Line Islands to the west side of the IDL (or, if you prefer, moving the IDL |
| 1649 | # to the east side of the Phoenix and Line Islands), I suppose that most |
| 1650 | # mapmakers redrew the IDL following the boundary of Kiribati. Even that line |
| 1651 | # has a rather arbitrary nature. The straight-line boundaries between Pacific |
| 1652 | # island nations that are shown on many maps are based on an international |
| 1653 | # convention, but are not legally binding national borders.... The date is |
| 1654 | # governed by the IDL; therefore, even on the high seas, there may be some |
| 1655 | # places as late as fourteen hours later than UTC. And, since the IDL is not |
| 1656 | # an international standard, there are some places on the high seas where the |
| 1657 | # correct date is ambiguous. |
| 1658 | |
| 1659 | # From Wikipedia <http://en.wikipedia.org/wiki/Time_zone> (2005-08-31): |
| 1660 | # Before 1920, all ships kept local apparent time on the high seas by setting |
| 1661 | # their clocks at night or at the morning sight so that, given the ship's |
| 1662 | # speed and direction, it would be 12 o'clock when the Sun crossed the ship's |
| 1663 | # meridian (12 o'clock = local apparent noon). During 1917, at the |
| 1664 | # Anglo-French Conference on Time-keeping at Sea, it was recommended that all |
| 1665 | # ships, both military and civilian, should adopt hourly standard time zones |
| 1666 | # on the high seas. Whenever a ship was within the territorial waters of any |
| 1667 | # nation it would use that nation's standard time. The captain was permitted |
