proposed tz changes for Argentina, Brazil, Russia, etc.
by Paul Eggert Nov. 22, 1996

Nov. 22, 1996

Here is a big batch of proposed changes to the tz database. Most of the changes here were suggested by data taken from the International Air Transport Association's Standard Schedules Information Manual (IATA SSIM), published semiannually. Gwillim Law sent in several very helpful summaries of the IATA's data after 1990, and he deserves a big round of applause for his contributions. All changes below are from the IATA SSIM data unless otherwise noted. * New entries: ** America/Goose_Bay, needed because east Labrador also observed double-DST in 1988 (from Shanks; I misread one of his tables). ** for Argentina, which was in time zone chaos in the early 1990s: America/Catamarca America/Cordoba America/Jujuy America/Mendoza America/Rosario ** for Brazil, since the equatorial part of Brazil does not observe DST and the boundaries have moved recently: America/Cuiaba America/Fortaleza America/Maceio ** Antarctica/Palmer, which used Argentine rules before the Falklands war, Chilean afterwards (from Ethan Dicks) ** Asia/Aqtobe, for central Kazakhstan (which now has 3 time zones). ** Australia/Lindeman, for the Holiday Islands off Queensland, which observed DST for a couple of years after Queensland stopped. ** Europe/Kaliningrad, for Russia's new time zone (as if they didn't have enough time zones already!). * Renamed entries (from yours truly) Asia/Aktau -> Asia/Aqtau (the more usual Kazakh-English transliteration) Europe/Kuybyshev -> Europe/Samara (the city changed names in 1991) * Make the following changes relevant to today's timestamps: ** Data (as opposed to sheer guesswork) are now available for the following countries after 1990: Brazil Cuba Falklands Jordan Lebanon Paraguay Syria ** Albania now uses EU DST rules. ** Azerbaijan is now at +4 with EU rules. It switched to +4 in 1992 but first observed DST this year. ** Belarus now uses Russian DST rules. ** Bulgaria uses E-Eur DST rules, not C-Eur. ** Egypt has changed rules a couple of times in the 1990s; it currently seems to use DST from Apr lastFri 0:00 to Sep lastFri 0:00. ** Georgia is now +5 (from Mathew Englander, quoting AP 1996-10-23 13:05-04). In 1992 it switched to E-Eur rules; in 1994 it switched to +4. ** Greenland uses EU DST rules, except Thule, which adopted USA DST rules in 1993. ** Guyana is at -4; assume a 1991 switch. ** Haiti changes its clocks at 1:00s, not 2:00. ** Iran reinstituted DST since 1991, and currently seems to switch near the equinoxes. ** Iraq changed rules in 1991 to Apr 1 and Oct 1. ** Jamaica stopped observing DST in 1984. ** Kazakhstan uses E-Eur DST rules, not Russian DST rules. ** Kirgizstan uses its own rules since 1991. ** Latvia switched in Sep, not Oct, this year (from Peter Ilieve). ** Libya reinstituted DST this year. ** Mongolia follows Russia since 1991, except it switches at 0:00 local time. ** Namibia adopted DST in 1994. ** New Zealand's Chatham Islands are always 45 minutes ahead of New Zealand, even during DST changes. ** Nicaragua is now at -5. ** Portugal's Azores now use EU DST rules, after dallying with +0 in 1992/1993. ** Romania now uses E-Eur DST rules, after using their own special case in 1991/1994. ** Russians prefer the abbreviations MSK/MSD to MOST/MOSST (from Andrey A. Chernov). ** Tunisia abolished DST in 1991. ** Turkey now uses EU DST rules. ** Turks & Caicos switch at 0:00, not at 2:00. ** Ukraine now uses EU DST rules, except for central Crimea, which changes at 0:00u. ** Vanuatu abolished DST in 1993. ** Etc/UTC, Etc/Universal, and Etc/Zulu now use the abbreviation `UTC' instead of `GMT' (from Markus Kuhn); similarly, Etc/UCT now uses `UCT'. * Make the following changes for older timestamps: ** Newfoundland's UTC offset adjusted by 8 seconds from 1884 to 1935 (from a better reading of Shanks). ** Yukon's time of switch on 1973-10-20 was 0:00, not 2:00 (from Mathew Englander). ** Colombia, Costa Rica and Nicaragua observed DST in 1992. ** Guatemala observed DST in 1991. ** Peru observed DST in 1993. ** Portugal's 1983-1992 rules were W-Eur, not EU. ** Russia's 1992 rules were to switch at 23:00 local time, not 2:00 standard time. ** Uruguay observed DST through 1992/1993. =================================================================== RCS file: RCS/africa,v retrieving revision 1996.12 retrieving revision 1996.12.1.1 diff -c -r1996.12 -r1996.12.1.1 *** africa 1996/11/05 18:50:12 1996.12 --- africa 1996/11/22 19:39:06 1996.12.1.1 *************** *** 4,15 **** # go ahead and edit the file (and please send any changes to # tz(a)elsie.nci.nih.gov for general use in the future). ! # From Paul Eggert <eggert(a)twinsun.com> (1996-09-03): # # A good source for time zone historical data outside the U.S. is # Thomas G.

The boundary between BR1 and BR2 ! # has never been clearly stated. They've simply been called East and West. ! # However, some conclusions can be drawn from another IATA manual: the Airline ! # Coding Directory, which lists close to 400 airports in Brazil. For each ! # airport it gives a time zone which is coded to the SSIM. From that ! # information, I'm led to conclude that the states of Amapa (AP), Ceara (CE), ! # Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do ! # Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST. ! ! # From Paul Eggert (1996-11-22): ! # Let's make the following assumptions: ! # ! # * All data in Shanks are correct through 1990.

1) It seems you forget to reflect recent official Moscow timezone rule change (Sep->Oct), I already send you update long time ago and you tell me that it is commited. 2) I still see MOST cruft, instead of commonly used MSK/MSD... I remember you agree to change those names back to MSK/MSD, but nothing happens too. Please fix this two problems and upload new tzdata1996m as soon as possible stop incoming chaos with Russian zone. It already hits: as first example wrong europe file was just commited to FreeBSD distribution. -- Andrey A. Chernov <ache(a)nagual.ru> http://www.nagual.ru/~ache/

Addition to Microsoft.au time thread
by Chris Carrier Nov. 18, 1996

Nov. 18, 1996

If you think Microsoft's time bug is funny, here is a real-space time zone situation I find even funnier. At the South Pole, day and night each last for six months; sunrise is at the September equinox, sunset at the March equinox, and the time of day in any zone is meaningless. However, the South Pole uses daylight saving time from the first Sunday in October to the third Sunday in March! The reason they do this is because they want to stay on the same time as McMurdo Sound, which uses DST, and the reason McMurdo uses DST is because they want to be on the same time as New Zealand, which uses DST (NZDST=GMT+13:00) on the abovementioned dates. Now that's funny!

DST and OS software
by Chris Carrier Nov. 17, 1996

Nov. 17, 1996

Which is why daylight saving time rules should NOT be incorporated into OS software -- because they continually change. I am wondering how many computers in the European Union (except UK/Ireland) went back to standard time September 29 when the EU didn't fall back until October 27, the former date being programmed into them when the code was written because the last Sunday in September was the rule then.

I don't really know at present. There was a report in the Independent (a UK `quality' paper which is unfortunately only available on the Internet via AOL, and possibly only European AOL at that) on 25 October that at least acknowledged that France would have to consult with the rest of the EU about it. It said that `Paris would ask Brussels' meaning ask the EC Commission to be exempted from the Summer Time Directive as soon as possible, either next year or 1998. If it goes into 1998 it will be the eighth Directive which is not yet finalised. I have asked my usual contact at the Commission's Edinburgh office but she can't say much about the state of this new Directive. The Commission has produced a proposal which continues the current rules for 1998--2001. It is now the Council of Ministers' turn to reach a common postion, and then approve that as a Directive. They haven't shown much inclination so far and my contact points out that she can only speak for the Commission, not the Council. The new Directive is supposed to be approved by 1 Jan 97 but I think that is vanishingly unlikely even without this new French move. The Independent report said: `After three months of discussion and two parliamentary reports, it is clear that France intends to rid itself of a device that its experts say no longer saves fuel or manpower, upsets farmers, reduces milk yields by almost one-third and disrupts children's body-clocks.' Polls show 70% of people against changing the clocks, but an even split on the question of which time to use all the year round. Farmers and families with children favour permanent summer time (UTC+2), business and transport organisations favour winter time (UTC+1). The French Senate said winter time would be a good compromise with the rest of the EU, obviously assuming it continues to change its clocks, as France would have the same time as the UK in the Summer and the same as Germany in the winter. Can any French reader of this list give any references to the two official reports, possibly even a quick summary? Don't be too surprised about the importance given to milk yields. Cattle are an important determinant of EU policy, as witnessed by the current BSE row. :-) Peter Ilieve peter(a)aldie.co.uk

Clock change orgy of 1996-10-27

More thoughts on the clock change orgy of 1996-10-27: >"Rob Jones 4-6597 MR Sys" > INTERNET:jones@mr.med.ge.com wrote: >Anyone willing to venture a guess as to the number of clocks involved ? >(including uwaves, vcrs, etc...) 11 clocks at my home, but only 3 people. In terms of number of people, the 1996-10-27 fall back probably was about equal to 1991-09-15, when China changed its clocks last; however, in terms of clocks changed, the 1996-10-27 event clearly set an all-time record given the higher development level and more consumer goods available in the US and EU; in my household there were five timing devices to be changed per person, and I imagine in China it would probably be closer to one device per five persons.

One interesting thing in our office is that we have flextime and management is trying to get rid of it and to have everyone work 8-17. Most people's day begins around 7:45, and I would say about 15% of the office is on the equivalent of "Daylight Extra" with a workday beginning at 7. We have one woman who works 6-15 and who therefore could be considered on "Double Daylight Extra." I also have an interesting story about my former office, in Sacramento, the capital of California. When I worked there a decade ago, we had people in the office from 7:00 to 20:00. Full time employees were allowed to choose when they could come into work provided they worked an 8 hours within those limits. Sacramento is located in a valley in which summer days are VERY hot (average 35c and it's gone as high as 44c) but nights are quite pleasant, with an overnight low of 15c. I reacted to this by going on what might be called "Darkness Extra"; during the months when DST was in effect I set my work hours for 11:00-19:45, the equivalent of two hours of *reverse* DST to let me enjoy the cooler evenings. Alas, eventually the office went back to normal hours (first people in at 7:00; last out by 17:45) and I had to as well. Peter Hullah > INTERNET:Peter.Hullah@eurocontrol.fr wrote: >Isn't it about time the world came to realise that we don't live by the >sun anymore and that spreading our sunlight more-or-less evenly around >noon no longer has any sense? Strongly disagree; if you work an 8 hour day on a day shift, half of it usually is before noon so the work day starts at 8 which makes the average wakeup time on workdays between 6 and 7, which is when the sun ought to rise. In June, therefore, DST makes sense and in October it does not. >I reckon everyone should add two hours >to their current standard time and stick to it all year round. I've always believed that what can be done an hour before sunrise is much pleasanter to do an hour after sunrise. >In answer to those who say "Just get up and go to bed two hours earlier" >we all live in a community, and one family stepping out of line two >hours is not on. Actually I have heard of a few cases of families with pre-school children where the sole/or both adults work the night shift and the kids follow suit, although this has to change when the kids go to school.

Had Boston (and all of New England) not been near the largest city and capital of the US, it might have. Consider there are many cities (Cincinnati, Louisville, Chatannooga, Tallahassee) which astronomically belong in the Central zone observe Eastern time, and large areas are on Central time when they astronomically belong on Mountain (most of the six states in a north- south row between North Dakota and Texas).

I've always thought the logical time to begin and end DST was at some time near the equinox when the sun is at least 1 hour earlier than the latest it does by standard time, and at least 1 hour later than the earliest it does by daylight time. DST should not be used short of an emergency during the time near winter solstice when the sun is rising <1 hour earlier than the latest it ever does by standard time, and if there is <2 hours between the earliest and latest sunrise, you don't have enough daylight to save to warrant DST!

I remember Block Island, RI, went on DST in November 1973 two weeks after they fell back. I know people who were in Indiana in the 1950s-60s who remember the post office being an hour ahead or behind of the rest of town, an unincorporated area of a county being on a different time than a county seat, and so on. When the Uniform Time Act of 1966 was passed, Indiana passed a law requiring one clock in each public building to observe UTAT and marked "Official Time" so localities could go about their merry way. >People seem reluctant to give up summer time, >as shown by popular support in the rest of Europe for changing from >September to October, but don't seem to think of demanding an earlier >start. I wonder if anyone took a poll on the popularity of summer time in the last week in October 1996, when Europe was actually on summer time, as opposed to earlier polls showing majorities in favor. >At least we are making progress here on the cooperation front, >at least until the French upset things by suggesting they would scrap >the whole idea. What is the status on that? Actually the situation in France (and Spain) is that they are already on year round daylight time since their 'standard' is GMT+1 instead of the GMT zone that (nearly all of) France and Spain are astronomically in. When they talk about 'summer time' what they really mean is DOUBLE summer time. It should be noted when the UK was on double DST during WW2 it always ended the second weekend in August or earlier except in 1944, and even then it ran only to mid-September. I can see objections to DDST on October 26th having more than a little merit.

> [Somebodies] unfortunately have a very childish, > ingnorant and it seems almost purely politically motivated approach to > daylight saving. ... But I digress... Daylight saving has always been a purely political phenomenon, an attempt to legislate reality. (Consider observance of summer time in tropical countries!) It is, and always will be, subject to all the foolishness that any purely political abstraction is. Tracking that foolishness in software is as thankless as it is necessary.

Of my trio of islands, Eigg and Canna are also privately owned (I don't know about Muck). I fail to see why owning land that is bounded by sea rather than land bounded by a more normal fence makes the owners any less subject to the Summer Time Act 1972 than I am. Don't you have laws in Australia? :-) Seriously, should the tz database document legal time, or should it also document other sorts of `custom and practice' time? If the latter I'm sure I can promulgate an Aldie time to be observed on my patch that would break something in the existing code. :-) Another nearby island, Rum (Rhum if you believe the Ordnance Survey) is also owned by a single organisation and is largely given over to research into Red Deer. Maybe I should suggest to Scottish Natural Heritage that their scientific work justifies keeping UTC all year round. > Australia's vying powers-that-be unfortunately have a very childish, > ingnorant and it seems almost purely politically motivated approach to > daylight saving. ... But I digress... We have the same thing. People seem reluctant to give up summer time, as shown by popular support in the rest of Europe for changing from September to October, but don't seem to think of demanding an earlier start. At least we are making progress here on the cooperation front, at least until the French upset things by suggesting they would scrap the whole idea. Peter Ilieve peter(a)aldie.co.uk
