Dec. 6, 1994

For the 1996 EC / EU daylight savings changes, we need at least four rulesets, one each for Western, Middle, and Eastern Europe (since the change is UTC, not local time), and one for GB-Eire (since they will continue to use `GMT' and `BST' instead of `WET' and `WET DST'). Perhaps the simplest thing is to use the existing ruleset names, using a comment to explain that as of 1996 the [WME]-Eur and GB-Eire rulesets use the EC rules. The biggest near-term problem in this area will be countries that currently differ from the EC rules only in that they switch at midnight UTC instead of the new standard 01:00. It will be a hassle to find exactly when they change their rules. We found out with Finland only because someone sent us a bug report. Countries in this category currently include Albania, Bulgaria, Estonia, Greece, Latvia, Lithuania, Moldova, Poland, Romania, Turkey, and Ukraine. Greece is the only country in this list that is required to change because it's in the EC, but most likely the rest will follow at some point. At the end of this message I enclose a patch addressing the above issues, along with the following: * The rules for South Australia and Victoria change, effective March. * There's a new Australia/Canberra zone, since Shanks says Canberra differed from NSW in 1981. This fixes an error in the 1981 NSW rule. * Pacific/Belau changes to Pacific/Palau (with a zone name change). (Palau is the world's newest country; we had been using an old name for it.) * The name of Kirgizstan's capital changed from Frunze to Bishkek. * The Cocos Islands are now in the correct ocean. * Norfolk Island's time zone name is now NRFT consistently. The following changes should be invisible to users. * NZ Rule lines now use standard time, to match the NZ Order in Council. * Add a story about Zurab Murvanidze, who cares about daylight savings time even more than we do. * Document that we typically use traditional English time zone abbreviations, but include the standardized Canadian French names as comments. * Add some cross-references. =================================================================== RCS file: RCS/africa,v retrieving revision 1994.4 retrieving revision 1994.4.1.1 diff -c -r1994.4 -r1994.4.1.1 *** africa 1994/02/07 14:57:48 1994.4 --- africa 1994/12/06 17:13:55 1994.4.1.1 *************** *** 53,58 **** --- 53,62 ---- # Omit `.' from abbreviations in names, e.g. prefer `St_Helena' # to `St._Helena'. # + # We typically use traditional English time zone abbreviations, + # and assume that applications translate them to other languages + # as part of the normal localization process. + # # I made up the following time zone abbreviations; corrections are welcome! # LMT Local Mean Time # -2:00 CVT Cape Verde Time (no longer used) =================================================================== RCS file: RCS/asia,v retrieving revision 1994.6 retrieving revision 1994.6.1.1 diff -c -r1994.6 -r1994.6.1.1 *** asia 1994/08/20 16:55:59 1994.6 --- asia 1994/12/06 17:13:55 1994.6.1.1 *************** *** 53,59 **** # 9:00 MLT Moluccas* # 9:30 CST Australian Central Standard Time # ! # See the `europe' file for Russia in Asia. # # See the `africa' file for Zone naming conventions. --- 53,59 ---- # 9:00 MLT Moluccas* # 9:30 CST Australian Central Standard Time # ! # See the `europe' file for Russia and Turkey in Asia. # # See the `africa' file for Zone naming conventions. *************** *** 277,282 **** --- 277,287 ---- 2:00 Cyprus EET%s # Georgia + # From Paul Eggert <eggert(a)twinsun.com> (1994-11-19): + # Today's _Economist_ (p 60) reports that Georgia moved its clocks forward + # an hour recently, due to a law proposed by Zurab Murvanidze, + # an MP who went on a hunger strike for 11 days to force discussion about it! + # Alas, we have no details. # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Tbilisi 2:59:16 - LMT 1880 2:59 - LST 1924 May 2 *************** *** 519,524 **** --- 524,534 ---- 5:00 - TSK 1957 Mar 6:00 Russia TS%s + # Kirgizstan + # Zone NAME GMTOFF RULES FORMAT [UNTIL] + Zone Asia/Bishkek 4:58:24 - LMT 1924 May 2 + 5:00 - TSK 1957 Mar + 6:00 Russia TS%s ############################################################################### *************** *** 555,571 **** ############################################################################### - # Kuwait # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Asia/Kuwait 3:11:56 - LMT 1950 3:00 - AST - - # Kyrgyzstan - # Zone NAME GMTOFF RULES FORMAT [UNTIL] - Zone Asia/Frunze 4:58:24 - LMT 1924 May 2 - 5:00 - TSK 1957 Mar - 6:00 Russia TS%s # Laos # Zone NAME GMTOFF RULES FORMAT [UNTIL] --- 565,574 ---- =================================================================== RCS file: RCS/australasia,v retrieving revision 1994.6 retrieving revision 1994.6.1.1 diff -c -r1994.6 -r1994.6.1.1 *** australasia 1994/08/20 16:56:00 1994.6 --- australasia 1994/12/06 17:13:55 1994.6.1.1 *************** *** 21,29 **** --- 21,31 ---- # 1944/1945 was just like 1943/1944; go with Shanks. # Zone NAME GMTOFF RULES FORMAT [UNTIL] + # Northern Territory Zone Australia/Darwin 8:43:20 - LMT 1895 Feb 9:30 - CST 1917 Jan 1 0:01 9:30 Aus CST + # Western Australia Zone Australia/Perth 7:43:24 - LMT 1895 Dec 8:00 - WST 1917 Jan 1 0:01 8:00 Aus WST 1974 Oct lastSun 2:00 *************** *** 33,38 **** --- 35,41 ---- 8:00 - WST 1991 Nov 17 2:00 8:00 1:00 WST 1992 Mar Sun>=1 3:00 8:00 - WST + # Queensland Zone Australia/Brisbane 10:12:08 - LMT 1895 10:00 - EST 1917 Jan 1 0:01 10:00 Aus EST 1971 Oct lastSun 2:00 *************** *** 45,50 **** --- 48,54 ---- 10:00 1:00 EST 1992 Mar Sun>=1 3:00 10:00 - EST + # South Australia # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule AS 1971 1985 - Oct lastSun 2:00 1:00 - Rule AS 1986 only - Oct 19 2:00 1:00 - *************** *** 52,59 **** Rule AS 1972 only - Feb 27 3:00 0 - Rule AS 1973 1985 - Mar Sun>=1 3:00 0 - Rule AS 1986 1989 - Mar Sun>=15 3:00 0 - !

Dec. 4, 1994

>So it's time to-- > * add a couple of "Rule EU" lines to the Europe file This raises an issue I have meant to mention before. At present the W-Eur, M-Eur and E-Eur rules only differ in the time of the summer time changes. The EC Directive is the same for everybody, and specifies a time of 01:00 GMT. Because various EU countries are in 3 different timezones the changeover times in their local standard times differ. What we need is something like a `u' or `g' suffix to go with the current s and w, to indicate a time in UTC/GMT. Then one EU rule could suit everybody. > * document the current EU membership The original six: Belguim, France, (West) Germany, Italy, Luxembourg, the Netherlands. Plus, from 1 Jan 73: Denmark, Ireland, United Kingdom. Plus, from 1 Jan 81: Greece. Plus, from 1 Jan 86: Spain, Portugal. Plus, from 1 Jan 95: Austria, Finland, Sweden. (Norway negotiated terms for entry but in a referendum on 28 Nov 94 the people voted No by 52.2% to 47.8% on a turnout of 88.6%. This was almost the same result as Norway's previous referendum in 1972, they are the only country to have said No twice. Referendums in the other three countries voted Yes.) Next in the queue for membership are probably the Czech Republic, Hungary and Poland; further back are the Baltic States, Bulgaria, Romania, Slovakia, Slovenia, whatever else emerges from the wreckage of Yugoslavia, etc., etc. > * document current nonmembers who are using EU rules (if any) The only one I can speak for is Estonia, which uses EU dates but not at 01:00 GMT, they use midnight GMT. I don't think they know yet what they will do from 1996 onwards. > * document current members who are not using EU rules (if any) There shouldn't be any of these. A Directive has the force of law, member states are obliged to enact national law to implement it. The only contentious issue was the different end date for the UK and Ireland, and this was always allowed in the Directive. Peter Ilieve peter(a)memex.co.uk

UK Summer Time Order 1994
by Peter Ilieve Dec. 1, 1994

Dec. 1, 1994

The final piece of the legislative jigsaw for summer time in the UK for 1995--97 is now in place. The Summer Time Order 1994 (SI 1994/2798) came into force on 16 November. It restates the dates from the EC seventh Summer Time Directive which are already reflected in the tzdata files. Peter Ilieve peter(a)memex.co.uk

The Internet address for elsie.nci.nih.gov has changed from 128.231.16.1 to 165.112.73.1; assuming the name servers do their things, this change should be invisible to folks who use the name rather than the address. --ado

One thing the multilingual handling stuff might not handle well would be the names of time zone files, which are what's used to establish the time zone to be used. A possibility here would be to take the tack used with the "backward" file in the distribution: set up a file (named, for example, "espanol") with lines such as Link America/Mexico_City America/Ciudad_Mejico and provide instructions on how system administrators can zic espanol to generate language-specific stuff. --ado

Canadian bilingual time zone names
by eggert＠twinsun.com Nov. 16, 1994

Nov. 16, 1994

I enclose below (with permission) copies of Usenet articles written by Alain LaBont<e'>, which cover the Canadian standard for multilingual time zone names. (I've told him about the tz tables.) At first I thought I'd propose to duplicate all the Canadian Zone and Rule lines, one copy for English and one copy for French. But now I'm not so sure, since this practice would greatly balloon the tables if we did it for all multilingual locations. The topic of multilingual time zone names seems to have slipped through the standardization cracks, since the LC_TIME environment variable doesn't address this issue. One way out of the problem would be to extend the syntax of the TZ environment variable to allow optional specification of the names of the standard and daylight zone names before the name of the file. E.g. `TZ=America/Halifax,HNA,HAA' for people in <I^>les-de-la-Madeleine who want French time zone names. This is a bit of a hack, since it doesn't address the issue of double-daylight zone names, or changes in zone names over time, but it may be the most practical solution. Another way would be to extend LC_TIME somehow to cover time zone names. This sounds less plausible to me, since there are dozens of time zones and most locales don't care about names of time zones on the other side of the planet. From: ALB(a)immedia.ca Newsgroups: comp.software.international Date: 14 Nov 1994 14:39:23 -0500 Message-ID: <3a8edb$781(a)senator-bedfellow.MIT.EDU> Now as promised, I post here the time zone abbreviations standardized in Canada for both English and French in CAN/CSA-Z234.4-89 standard (I have added notes and corrected minor typos still in the standard/ the abbreviations and numeric and alphabetic time zones are correct in the standard, what I corrected would not change any technical content). Table A2 - Canadian Time Zones Abbreviations (Abr<e'>viations des fuseaux horaires pour le Canada) Standard Time Daylight Saving Time ITU Designator Hours West French English French English of UTC HN- -ST HA- -DT 2-1/2 - - HAT NDT - 3 - - HAA ADT P 3-1/2 HNT NST - - - 4 HNA AST HAE EDT Q 5 HNE EST HAC CDT R 6 HNC CST HAR MDT S 7 HNR MST HAP PDT T 8 HNP PST HAY YDT U 9 HNY YST - - V HN stands for "Heure normale"/HA stands for "Heure avanc<e'>e" ST stands for "Standard Time"/DT stands for "Dailight saving Time" Prefix/Suffix meaning (note from ALB: I added the appropriate prepositions and articles "du, de l', des, de" for non-French speakers, so that the information of the standard be completed for them - this data is not in any version of the std.): A: Atlantic/de l'Atlantique C: Central/du Centre E: Eastern/de l'Est M: Mountain (note from ALB: see R for French) N: Newfoundland (note from ALB: see T for French) P: Pacific/du Pacifique R: des Rocheuses (note from ALB: see M for English) T: de Terre-Neuve (note from ALB: see N for English) Y: Yukon/du Yukon Note: The standard says (I cite the English version textually): "Although there is no ISO standard on time zone designators, the letters given in table A1 have been adopted by the International Telecommunication Union (ITU/[UIT in French]), a UN ["Nations Unies" in the French version, normally abbreviated ONU] special agency having the status of treaty organization regarding radio operations and regulations. Within North America the abbreviations given in table A2 are also used." The standard also deals with all-numeric dates and times (Repr<e'>sentation num<e'>rique de la date et de l'heure). I invite those who want non-time-zone-related information on this subject to buy the standard from CSA (Canadian Standards Association/Association canadienne de normalisation) sales offices throughout the world. I only cited here the full table A2. Table A1 starts with Z for UTC, goes from A to M East of UTC (with M as a half-zone) and N to Y West of UTC (with Y as a half-zone); the Newfoundland half-zone does not seem covered by ITU/UIT, despite it is on the soil where the first transatlantic (first long range) radio transmissions were done by Marconi. Quarter zones are not covered either by ITU, even if this does not affect Canada, but certain countries. I also think that what would be good to document would be the dates on which standard and daylight-saving time changes are done throughout the world. I have not found that data in any place. I think it can *not* be done only on ITU designators, as it has to take into account at least Northern/Sourthern hemisphere and even national/multinational conventions and laws (for example, this fall, Britain, Europe and North America have all switched to Standard Time at different dates [3 dates...], sometimes at weeks of interval !!!) For other countries it is quite problematic... from time to time, laws change too. Perhaps there is a need for a worldwide registration authority for that matter.

Envoyeur: RNET (ALB(a)immedia.ca) Date : 11/15/94 Time : 21:17 ---------- It is interesting to note that there is a mnemonic way to remember the time zone codes attributed by ITU for North America. Q applies to at least one of the two time zones of Quebec at any time of the year (Eastern Daylight Time in the summer, Atlantic Standard Time in the winter). Remember "Quebec in the summer", the most beautiful time of the year... For R, remember "Rivi<e`>re-du-loup West of the Atlantic": (see below) 4 HNA AST HAE EDT Q 5 HNE EST HAC CDT R FYI: Atlantic time zone used to begin West in Rivi<e`>re-du-loup when I was a teenager (to respect exact time zone calculations that divides the world into 24 equal parts). For convenience, all continental Quebec is on Eastern Time all the time now while the Atlantic Time Zone, because it is quite far East, applies to <I^>les-de-la-Madeleine, which is predominently-French-speaking Quebec even if you have to cross 2 other provinces (NB and PEI) to access it (it was populated by deported Acadians, and more recently by St.Pierrans and Miqueloners [from "neighbouring" St-Pierre-et-Miquelon, France]). On the continent, in Canada, you cross the Eastern zone to the Atlantic zone when you cross the bridge between Quebec and New Brunswick (between Matap<e'>dia and Campbelton). Interesting to note also that in the aviation jargon worldwide, the letter Q is pronounced Quebec (ALPHA... BRAVO... ... QUEBEC ... TANGO ... ZULU). When taking my first flight lessons at the Quebec airport in the eighties, I was puzzled about why they were identifying the control tower by "QUEBEC BRAVO" ("Why were they adding BRAVO?", I did not know... at the second lesson I heard it was the standard way of identifying the airport, whose code is YQB! [Y is for Canada and is obvious, it seems]) Z (i.e. ZULU) is assigned to UTC time zone (i.e. the time zone whose centre is at the Greenwich Observatory Meridian).

The "Names & Faces" column in the Monday, October 31, 1994 Washington (DC) Post, page D3 (compiled from staff and wire reports by Marla Harper) contains a "Daylight-Saving Bust" item. Erik (son of Kirk) Douglas was arrested after arguing with a Denny's manager who wouldn't serve him a drink. "...Douglas had insisted he be served, saying the one-hour shift to Pacific Standard Time made it 1 a.m.-- and within the 2 a.m. cutoff for alcohol sales..." --ado
