Time zone files in tzdata96i.tar.gz
by Brian Candler March 30, 1997

March 30, 1997

Package: tzdata95i.tar.gz [from RedHat zoneinfo-96i-4.i386.rpm] Symptom: The timezone /usr/lib/zoneinfo/Etc/GMT-6 does not work correctly; if you use it, then set your clock using ntpdate, the system clock is 12 hours out. However if you use a different zoneinfo (e.g. America/Belize) it works fine. I believe the problem is in file "etcetera" in the tzdata package: ... Zone Etc/GMT-6 6 - GMT-6 Zone Etc/GMT-5 5 - GMT-5 Zone Etc/GMT-4 4 - GMT-4 ... Zone Etc/GMT+4 -4 - GMT+4 Zone Etc/GMT+5 -5 - GMT+5 Zone Etc/GMT+6 -6 - GMT+6 ... It appears that the zone offsets in column 3 have the wrong sign - can you check if this is the case? Regards, Brian Candler.

proposed changes to tz data from 1997-02 IATA tables, etc.
by Paul Eggert March 28, 1997

March 28, 1997

Here are proposed changes for for the following countries, taken from the changes in the 1997-02 IATA tables reported by Gwillim Law. Brazil Cuba Libya Mongolia New Caledonia Paraguay Sri Lanka [with transition time found via Deja News] This change also incorporates the simpler (and hopefully more accurate) prediction for Israel that I mentioned earlier on this list. Also, it contains commentary updates for several locations (mostly peri-Antarctic islands) that should be self-explanatory, and it adds some new URL references and removes one or two dangling URLs. =================================================================== RCS file: RCS/WWW,v retrieving revision 1996.5 retrieving revision 1996.5.1.1 diff -c -r1996.5 -r1996.5.1.1 *** WWW 1996/01/06 14:08:24 1996.5 --- WWW 1997/03/29 07:34:37 1996.5.1.1 *************** *** 1,6 **** # '@(#)WWW 7.3' ! # From Paul Eggert <eggert(a)twinsun.com> (1995-11-03) # # The Web has several other sources for time zone and daylight savings data. # Here are some recent links that may be of interest. --- 1,6 ---- # '@(#)WWW 7.3' ! # From Paul Eggert <eggert(a)twinsun.com> (1997-03-28) # # The Web has several other sources for time zone and daylight savings data. # Here are some recent links that may be of interest. *************** *** 10,15 **** --- 10,20 ---- # A text-based source for tables of current time throughout the world. # Its point-and-click interface accesses a recent version of the tz data. # + # WORLDTIME: interactive atlas, time info, public holidays + # http://www.worldtime.com/ + # Interactive world atlas with information on local time, sunrise and sunset, + # and public holidays in several hundred cities around the world. + # # Local Times Around the World # http://www.hilink.com.au/times/ # This text-based system contains links to local time servers *************** *** 18,38 **** # # World Time Zones # http://tycho.usno.navy.mil/tzones.html ! # US Naval Observatory data, used as the source for `usno1995'. # # Standard Time Zones of the World ! # http://www.odci.gov/cia/publications/95fact/802389.gif [54 kB] ! # http://www.odci.gov/cia/publications/95fact/802389h.gif [1317 kB] ! # A static time zone map, available in both low-resolution and ! # high-resolution versions.

Timezone changes reported in IATA manual
by gwil＠mindspring.com March 28, 1997

March 28, 1997

I've received the February 1997 edition of the Standard Schedules Information Manual, published by the International Air Transport Association (IATA). This manual has an appendix of international time zone information, which is intended for use by member airlines in generating and interpreting their service schedules. I compared it line by line with the previous (September 1996) edition. This is a report on the differences. In the following table, "edit" is the date of the edition. "zon" is a code for the time zone, consisting of the ISO 3166 country code followed by a digit, where necessary, to distinguish between different zones in the same country. "stdoff" and "dstoff" are the offsets from GMT to standard time and daylight saving time in the zone, respectively. The rest of each line consists of two pairs of consecutive dates for the beginning and end of daylight saving time in the zone, expressed in UTC (without the century, to save space). For time zones that don't observe DST, the last five columns are blank. For countries in the Southern Hemisphere, the four dates represent the same years. For countries in the Northern Hemisphere, the last two dates reported in the 9/96 manual correspond to the first two dates in the 2/97 manual. To help compare the two rows, I've flagged the items in the second row that differ from the first row, or from what you would expect to find in the continuation of the first row. I hope that line wrapping won't make this table too hard to read. edit zon stdoff dstoff 1st dst start 1st dst end 2nd dst start 2nd dst end ---- --- ------ ------ --------------- --------------- --------------- --------------- 9/96 BR1 -3:00 -2:00 Oct 13 96 03:00 Feb 16 97 02:00 Oct 12 97 03:00 Feb 15 98 02:00 2/97 BR1 -3:00 -2:00 Oct 6 96 03:00 Feb 16 97 02:00 Oct 5 97 03:00 Feb 15 98 02:00 ^^ ^^ 9/96 BR2 -4:00 -3:00 Oct 13 96 04:00 Feb 16 97 03:00 Oct 12 97 04:00 Feb 15 98 03:00 2/97 BR2 -4:00 -3:00 Oct 6 96 04:00 Feb 16 97 03:00 Oct 5 97 04:00 Feb 15 98 03:00 ^^ ^^ 9/96 CL1 -4:00 -3:00 Oct 13 96 04:00 Mar 9 97 03:00 Oct 12 97 04:00 Mar 8 98 03:00 2/97 CL1 -4:00 -3:00 Oct 13 96 04:00 Mar 9 97 03:00 Oct 12 97 04:00 Mar 15 98 03:00 ^^ 9/96 CL2 -6:00 -5:00 Oct 13 96 06:00 Mar 9 97 05:00 Oct 12 97 06:00 Mar 8 98 05:00 2/97 CL2 -6:00 -5:00 Oct 13 96 06:00 Mar 9 97 05:00 Oct 12 97 06:00 Mar 15 98 05:00 ^^ 9/96 CU -5:00 -4:00 Apr 7 96 05:00 Oct 6 96 05:00 Apr 6 97 05:00 Oct 5 97 05:00 2/97 CU -5:00 -4:00 Apr 6 97 05:00 Oct 12 97 05:00 Apr 5 98 05:00 Oct 11 98 05:00 ^^ ^^ 9/96 GE 4:00 5:00 Mar 30 96 20:00 Oct 26 96 19:00 Mar 29 97 20:00 Oct 25 97 19:00 2/97 GE 5:00 9/96 IL 2:00 3:00 Mar 14 96 22:00 Sep 15 96 21:00 Mar 13 97 22:00 Sep 14 97 21:00 2/97 IL 2:00 3:00 Mar 13 97 22:00 Oct 18 97 21:00 Mar 19 98 22:00 Oct 17 98 21:00 ^^^^^^ ^^^^^^ 9/96 KI2 -10:00 2/97 KI2 14:00 ^^^^^^ 9/96 KI3 -11:00 2/97 KI3 13:00 ^^^^^^ 9/96 KG 5:00 6:00 Apr 13 96 19:00 Sep 28 96 18:00 Apr 12 97 19:00 Sep 27 97 18:00 2/97 KG 5:00 6:00 Apr 12 97 19:00 Sep 27 97 18:00 Apr 11 98 19:00 Oct 26 98 18:00 ^^^^^^ 9/96 LY 1:00 2:00 Mar 30 96 01:00 Sep 30 96 01:00 Mar 30 97 01:00 Sep 30 97 01:00 2/97 LY 1:00 2:00 Mar 27 97 01:00 Oct 2 97 01:00 Mar 26 98 01:00 Oct 1 98 01:00 ^^^^^^ ^^^^^^ ^^^^^^ ^^^^^^ 9/96 MN 8:00 9:00 Mar 30 96 16:00 Oct 24 96 15:00 Mar 29 97 16:00 Oct 23 97 15:00 2/97 MN 8:00 9:00 Mar 29 97 16:00 Sep 27 97 15:00 Mar 28 98 16:00 Sep 26 98 15:00 ^^^^^^ ^^^^^^ 9/96 NC 11:00 2/97 NC 11:00 12:00 Nov 30 96 15:00 Mar 1 97 15:00 Nov 29 97 15:00 Mar 7 98 15:00 9/96 PY -4:00 -3:00 Oct 1 96 04:00 Mar 1 97 03:00 Oct 1 97 04:00 Mar 1 98 03:00 2/97 PY -4:00 -3:00 Oct 6 96 04:00 Mar 1 97 03:00 Oct 1 97 04:00 Mar 1 98 03:00 ^^ 9/96 LK 6:30 2/97 LK 6:00 9/96 UA1 2:00 3:00 Mar 31 96 01:00 Oct 27 96 01:00 Mar 30 97 01:00 Oct 26 97 01:00 2/97 UA1 2:00 3:00 Mar 30 97 03:00 Oct 26 97 04:00 Mar 29 98 03:00 Oct 25 98 04:00 ^^^^^ ^^^^^ ^^^^^ ^^^^^ Descriptions of the changes shown in these manuals are as follows. I've had to make assumptions in order to state the rules. All I can say for sure is that they're consistent with the data. The rules are expressed in local time, with midnight counting as the following day. Brazil has changed the end of DST from the second to the first Sunday in October, starting in 1996. (Actually, the rule implied by previous manuals was Oct Sun>10 or Sun>11, from 1993 to 1997.) Chile has changed the end of DST from the second to the third Sunday in March, starting in 1998. Cuba has changed the end of DST from Oct Sun>4 to Sun>5 (or more), starting in 1997. Georgia has gone on year-round standard time using its former DST offset, probably by failing to change the clocks back in October, 1996. Israel has changed the end of DST from the third Monday in September to the third Sunday in October, starting in 1997. The parts of Kiribati that were east of the International Date Line have set their calendars ahead one day, so that at most times Kiribati will have a uniform date. There's no evidence in the manuals as to when this took effect, but it's also been reported in the news. Kyrgyzstan has changed the end of DST from the last Sunday in September to the last Tuesday in October, starting in 1998. This may be a typo in the manual. If it said Sep 26 instead of Oct 26, that would be consistent with the old rule. Besides, Tuesday is a rather unusual day for DST to end on. Libya has changed the start and end of DST from fixed dates to the last Thursday in March and the first Thursday in October, respectively, starting in 1997. Mongolia has changed the end of DST from the fourth Friday in October to the fourth Sunday in September, starting in 1997. (The October rule only lasted for one year, 1996.) New Caledonia has adopted DST, beginning December 1, 1996 (local time). Paraguay started DST on October 6 instead of October 1 in 1996 only. Sri Lanka has set its clocks back a half hour. There's no evidence in the manuals as to when this took effect. Ukraine, except for Symferopol, has changed the time at which DST begins to 05:00, and the end time to 07:00 (local time). This is rather unusual, and I suspect an error in the manual. There were three other entries in the manual where I am convinced that IATA made an error. I fixed the errors and didn't list them as changes above. Just for the record, here they are. The manual says that: (1) Gibraltar has moved its winter time an hour earlier, but not its summer time, so that in the winter it matches the United Kingdom and in the Summer it matches mainland Spain, with a two-hour change each time. (2) DST ends one day earlier in Kaliningrad Oblast than in the rest of Russia, although it starts on the same day and hour. This is an error that has occurred in previous editions. When the times are expressed in UTC, Kaliningrad is the only one that changes at or after midnight, so the error is easily explained. Someone copied the date for all the Russian entries without noticing that it should have been the following date in Kaliningrad. (3) In Symferopol, the offset from UTC to standard time is three hours. The manual reports that the offset for DST is four hours in 1997, but three hours in 1998. If that were really true, there would be no point in their reporting the DST start and end dates for 1998, because DST would be the same as standard. Note to Paul Eggert: I'll send you new files with these changes incorporated as soon as I have time (probably not in the next week). -- Gwillim Law Gwillim Law gwil(a)mindspring.com

Progress on summer time directive for the European Union
by peter＠aldie.co.uk March 28, 1997

March 28, 1997

The Transport Council discussed the proposed Eighth Directive on 11 March and agreed it, so it moves forward to the next stage, from a Commission proposal to a Common Position. Many EU documents are now available on the WWW as the EU have opened the previously subscription only RAPID database to everyone. The report of this transport council took a while to arrive but it is there now. RAPID as available at http://europa.eu.int/en/comm/spp/rapid.html The document reference is PRES/97/70, or you can search for `transport council', or you can try the following long URL for the English text version: http://europa.eu.int/rapid/cgi/rapcgi.ksh?p_action.gettxt=gt&doc=PRES/97/70… It is available in PDF as well, and also in French. The section about Summer Time is quoted below: --------- SUMMER-TIME ARRANGEMENTS The Council reached political agreement by a qualified majority, with France voting against, on a common position prior to adoption of the eighth Directive on summer-time arrangements. Once formally adopted, the common position will be forwarded to the European Parliament for a second reading, in accordance with the co-decision procedure. The aim of the eighth Directive is to harmonize the dates and times for the beginning and end of summer time throughout the Community for the period from 1998 to 2001. In addition, the Council and the Commission approved the following joint declaration: "The Council and the Commission consider that the social and economic implications of the decisions concerning summer-time arrangements justify thorough examination, which will be effected before the eighth Directive elapses. For this purpose, the Commission will forward a detailed report to the Council by 30 June 1999 at the latest, and the Council and the Commission agree to carry out, with the aid of a group comprising representatives of interest groups and Member States' national experts, an in-depth examination of the implications of applying summer-time arrangements, including the institutional aspects of coordination of times between the Member States of the European Union." Furthermore, the United Kingdom made the following unilateral statement: "The United Kingdom states that, while it has no difficulties with the substance of the proposed eighth summer-time Directive, on subsidiarity grounds it considers that Member States' summer-time arrangements would be best addressed in a Recommendation." --------- What this means is: - The eighth directive proposal rules have been accepted. These are the same as the current rules (last Sunday in March and last Sunday in October). The rules will run until 2001. - The French have had their request to abandon summer time turned down. They have been promised some sort of review in 1999 which might change the rules for 2000 and 2001. I personally doubt that anything will happen before a ninth directive as there won't be the time to go though all the necessary steps between 30 June 1999 and March 2000. These people have no sense of deadlines and they will probably all be caught up in Millennium projects by then anyway. - The UK were just stirring things up. Subsidiarity is a Maastricht Treaty buzzword meaning that member states should be free to decide things for themselves unless it is really necessary for things to be done at a European level. A Recommendation rather than a Directive would allow states to ignore it and France could abandon summer time if it felt like it. It is interesting to see the UK using this subsidiarity argument as by doing so they are saying that there is no need to harmonise time arrangements in Europe. This means they will not be able to use the harmonisation argument next time the question of changing the UK's timezone comes up. The next stage is to let the European Parliament have their say, although I don't think they have the power to amend it. Then it is finally confirmed by the Council. This probably won't happen until May. The UK government then has to pass a Staturary Instrument to implement the Directive. My guess is that they won't manage this before Parliament rises for the summer recess so it won't happen until about October. Peter Ilieve peter(a)aldie.co.uk

This may have been only a one-year thing, as I remember someone quoting Georgia's President, Schevrednaze (I believe that is the spelling) saying that Georgia would be remaining on DST "this winter" (1996-7) "to save energy." Anyone heard anything about permanent change in Georgia? >Kyrgyzstan has changed the end of DST from the last Sunday in September to >the last Tuesday in October, starting in 1998. This may be a typo in the >manual. If it said Sep 26 instead of Oct 26, that would be consistent with >the old rule. Besides, Tuesday is a rather unusual day for DST to end on. I tend to think typo as well, but they may have changed to the last Sunday in October; as you said, Tuesday is an unusual day for a time change. >Sri Lanka has set its clocks back a half hour.

I fixed the errors and didn't list them as changes above. >Just for the record, here they are. The manual says that: >(1) Gibraltar has moved its winter time an hour earlier, but not its summer >time, so that in the winter it matches the United Kingdom and in the Summer >it matches mainland Spain, with a two-hour change each time. I actually believe this may not be an error. I called up AT&T International Operator twice on two successive nights and they said they have no listing for Gibraltar. I asked for the time in Morocco and was given GMT. Now given that Gibraltar is a British possession and is next to both Morocco and Spain, I can see them staying on GMT in winter and Spanish time in summer. To move in one year from standard time to two hours of DST and back to standard, either in one jump (Newfoundland 1988) or in two one hour jumps (UK 1947) can happen from time to time. BTW, I'm less convinced than I used to be of the infallibility of AT&T, although I still consider it to be the best source available for current time data. This is because they moved the EU back to standard time on 1996 Sep 29, and a couple of weeks later, moved them back ahead, only to then move them back on the actual date of October 27. Would like to ask: is Mexico going to go on DST in 1997 and after? Chris Carrier

I apologize for sounding testy. It's frustrating enough keeping up with all the foolishness of law without entertaining suggestions for policy improvements we have no hint of authority to act on. This list is the place changes to the tz database are discussed, and we those of us who follow it must subscribe to keep informed. I meant the suggestion to post in a more appropriate place seriously: your wise analysis is wasted where no reader can act on it. I also meant seriously the suggestion to start a more appropriate list. People who understand politics should be involved, and they are not here. Nathan Myers ncm(a)cantrip.org
