proposed tz changes for Argentina, Jordan, Paraguay, Sudan
by Paul Eggert March 3, 2000

March 3, 2000

Here are some proposed changes to the tz database. The most pressing changes are for Argentina (where the old tz database becomes incorrect on Sunday) and for Sudan (where it became incorrect on January 15). * Argentina has stopped using DST; it will not move its clocks ahead this Sunday. (Thanks to Peter Gradelski via Steffen Thorsen for this info.) * As of last fall, Jordan's DST rules are from March's last Thursday to September's last Thursday, switching at 00:00. (Thanks to Gwillim Law for this info.) * As of last spring, Paraguay begins DST on October's 2nd Sunday, not its 1st. (Thanks to Gwillim Law for this info.) * Sudan switched to UTC+3 on January 15. (Thanks to Michael De Beukelaer-Dossche via Steffen Thorsen.) * In tz-link.html: - Place "Time and The Arts" in the same category as dmoz and yahoo. - Create a new category for non-web tz-based software, and add a Windows app. - Add a pointer to NTP. * Fix some HTML nonconformance glitches, and make some phrases more consistent. * Update some obsolete email addresses. =================================================================== RCS file: RCS/africa,v retrieving revision 1999.9 retrieving revision 1999.9.0.1 diff -pu -r1999.9 -r1999.9.0.1 --- africa 1999/11/08 22:27:22 1999.9 +++ africa 2000/03/03 05:53:27 1999.9.0.1 @@ -10,7 +10,7 @@ # Thomas G.

February 2000 SSIM data
by Law, Gwil Jr. March 1, 2000

March 1, 2000

I have received the February, 2000 edition of the Standard Schedules Information Manual (SSIM) from IATA. What follows is a narrative list of changes from the previous edition (September, 1999). It may be that neither edition is completely correct, but differences between them are probably indicative of actual changes in the real world. Argentina: had been on UTC-3 for several years. The new SSIM says that Argentina is using UTC-4 as its standard time and observing DST throughout the country from midnight (local time) at the start of the first Sunday in October until midnight (local DST) start of the first Sunday in March. As usual, there is no indication of when this change took effect. Although the SSIM lists the beginning of DST in October, 1999, it may be that Argentina simply remained on standard time last October, but started thinking of it as DST. Australia: Tasmania will deviate from its normal rule to begin DST on August 27, 2000, in synch with Sydney. Brazil: A number of states that didn't observe DST are supposed to have begun using it on October 3, 1999. They are Alagoas, Sergipe, Ceara, Maranhao, Paraiba, Pernambuco, Piaui, and Rio Grande do Norte (UTC-3 standard time), and Roraima (UTC-4). Chile: will switch to DST on October 15, 2000, instead of October 8 as previously reported. The end of DST has been moved a week earlier, to come on the second Sunday of March instead of the third. Estonia: will remain on standard time (UTC+2) year-round. Israel: the dates for the beginning and end of DST in 2000 have been changed to April 14 and September 14, respectively. The dates for the following two years remain unchanged. Jordan: was shown remaining on standard time year round in the SSIM dated September, 1999 only. In all other editions since 1991, including the present one, it is shown on UTC+2, with DST in the summer. The change dates shown in the February, 2000 edition are different from previous editions. It says that DST runs from midnight (local time) at the start of the last Thursday in March until 1:00 (local DST) of the last Thursday in September. Lithuania: is said to have moved from UTC+1 (with DST) to UTC+2 (with DST). The dates and times of DST start and end, shown in UTC, are unaltered. There is no indication of when this change occurred. Paraguay: The beginning of DST in 1999 has been changed from October 3 to October 10, in both cases at midnight local time. Sudan: changed from UTC+2 to UTC+3. Tonga: For 1999-2000 only, Tonga is shown observing DST from 2:00 (local time) on October 1, 1999 to 3:00 (local DST) on April 15, 2000. Yours, Gwillim Law
