Best of Zones
by Gilbert C Healton April 2, 2002

April 2, 2002

For quite a few years now I have had documentation on the web for software developers involved with calendars, dates, times, and time zones. While the original motivation for this document was Y2K avoidance and correction the document goes a lot deeper into proper use of dates and times. After some lurking here it just struck me that some readers in this group might have some good ideas about ways programmers frequently go wrong with time zone processing or good ways of processing zones that are too little used. Any worthy ides not already covered by my document that would be useful to programmers are solicited. The Best of Dates, the Worst of Dates. http://www.exit109.com/~ghealton/y2k/yrexamples.html ---------------------------------------------------------------------- ghealton(a)exit109.com http://www.exit109.com/~ghealton/ ---------------------------------------------------------------------- Computers are like air conditioners: they don't work well when Windows are left open

symlinks
by Olson, Arthur David (NCI) April 2, 2002

April 2, 2002

Lacking consensus on the symlink problem, what I'd suggest for now is a change to zic.c that would only deal with the problem of creating symlinks to files that don't exist--see below. If making just this change for now is agreeable to folks, I'll update tzcode and tzdata once Paul Eggert weighs in with Paul's conclusions on what Estonia should look like. --ado *** 7.104/zic.c Tue Apr 2 09:58:10 2002 --- 7.107/zic.c Tue Apr 2 09:58:11 2002 *************** *** 1,6 **** #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)zic.c 7.104"; #endif /* !defined NOID */ #endif /* !defined lint */ --- 1,6 ---- #ifndef lint #ifndef NOID ! static char elsieid[] = "@(#)zic.c 7.107"; #endif /* !defined NOID */ #endif /* !defined lint */ *************** *** 620,626 **** result = link(fromname, toname); #if (HAVE_SYMLINK - 0) ! if (result != 0) { const char *s = tofile; register char * symlinkcontents = NULL; while ((s = strchr(s+1, '/')) != NULL) --- 620,628 ---- result = link(fromname, toname); #if (HAVE_SYMLINK - 0) ! if (result != 0 && ! access(fromname, F_OK) == 0 && ! !itsdir(fromname)) { const char *s = tofile; register char * symlinkcontents = NULL; while ((s = strchr(s+1, '/')) != NULL)

proposed tz changes for Pakistan, Estonia, Mexico, Paraguay, ...
by Paul Eggert March 27, 2002

March 27, 2002

Here are proposed changes to help keep the tz database up to date. Some changes noted below take effect as soon as this weekend. As usual, thanks to everyone who writes in and keeps us up-to-date. * Pakistan will observe daylight saving from the first Sunday after the first Saturday in April at 00:00 until October 15 at 00:00. (Thanks to Rives McDow for the heads-up, and to Jesper Norgaard for digging up a written reference, with different rules alas.) * Estonia will start observing daylight saving time again this year, using EU rules. (Thanks to Toomas Soome for this info.) * This year, Mexico will change back to using US daylight-saving rules. (Thanks to Jesper Norgaard Welen for this info.) * Starting next month, Paraguay observes DST from the first Sunday in September at 00:00 to the first Sunday in April at 00:00. (Thanks to Rives McDow for this info.) * Ujung Pandang has changed its name to Makassar. (Thanks to Priyadi Iman Nurcahyo for this info.) * Update Argentine historical time zone info, after reviewing an Argentine web site devoted to the subject, along with the corrections that Shanks made in his 5th edition. (Thanks to Javier Reinoso for the heads-up.) This results in the following changes: - No DST was observed from mid-1974 through mid-1988. - 1966/1967 DST ended on 1967-04-02, not 1967-04-01. - Argentine standard time was introduced 1894-10-31, not 1894-11-01. - Argentine standard time from 1894-10-31 through 1920-04-30 was -4:16:48.25, not -4:16:44. - Rosario and Cordoba have the same time zone history since 1970, so we should mark the America/Rosario Zone as obsolescent. - Many of the transition dates in 1991 and 1992 are incorrect. * It appears that there was widespread disagreement about the clocks in Argentina in 1991 and 1992. Record what Shanks writes, as comments, even though we may not agree with them. * Update the web page as follows: - Fix out-of-date URLs for Shanks's books, Russian time zones, Israeli announcements, Langley's notes, McCarthy & Klepczynski's proposal. - Fix out-of-date title for NTP. - Use briefer text for Pollastri's web page.

TZ data for Estonia
by Mart Oruaas March 22, 2002

March 22, 2002

Hello, After a lot of political fuzz, DST was suddenly reestablished in Estonia just a bit more than a month before the actual switchover date. According to Government's regulation no. 84 (2002-02-21, VVm RT I 2002, 22, 127). The funny side is that this regulation is fundamentally broken and all those people are blindly going to follow what was written in a press release by Government's Press Office. ;-) # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Europe/Tallinn 1:39:00 - LMT 1880 1:39:00 - TMT 1918 Feb # Tallinn Mean Time 1:00 C-Eur CE%sT 1919 Jul 1:39:00 - TMT 1921 May 2:00 - EET 1940 Aug 6 3:00 - MSK 1941 Sep 15 1:00 C-Eur CE%sT 1944 Sep 22 3:00 Russia MSK/MSD 1989 Mar 26 2:00s 2:00 1:00 EEST 1989 Sep 24 2:00s 2:00 C-Eur EE%sT 1998 Sep 22 2:00 EU EE%sT 1999 Nov 1 2:00 - EET 2002 Feb 21 2:00 EU EE%sT PS. please omit my e-mail address from the zone data file. -- /* Mart Oruaas Systems Engineer, IT dept.

RE: Pakistan

I found a government page with the same information, possibly the origin of it, on http://www.pak.gov.pk/public/news/app/app06_dec.htm There is more information on other issues, but the wording of the DST bit is the same. On a personal note they are really trying to test the limit of timezone handling software, choosing First Saturday and First Sunday of a month as a parameter, probably not realizing that these can be mutually exclusive, maby meaning that if First Sunday is first day of month, it will not be counted (as in 2007). Choosing fixed date 15.th. of October as DST end date, when the start date is parameterized to a weekend, is highly obscure too - but not difficult to handle.

This agrees with your April 7 at 00:00, but disagrees about the October transition, and makes it sound like it's not on a trial basis. Also, the "between the first Saturday and Sunday of April" phrase, if taken literally, means that the transition takes place at 00:00 on the first Sunday on or after April 2, not the more-usual April 1. The first year that this would make a difference is 2007. For what it's worth, Shanks says that the last transition from DST in what is now Pakistan also occurred at 00:00 on October 15. The year was 1945.

Dear Arthur and all, I have been advised that Pakistan has decided to adopt dst on a TRIAL basis for one year, starting 00:01 local time on April 7, 2002 and ending at 00:01 local time October 6, 2002. This is what I was told, but I believe that the actual time of change may be 00:00; the 00:01 was to make it clear which day it was on. Rives

Summer time in Mexico (fwd)
by Steffen Thorsen March 13, 2002

March 13, 2002

Hi, I'm sending this on behalf of Jesper Norgaard Welen <timezone50(a)hotmail.com> =============================================================================== I hadn't seen any news about the pending decision of Congress in Mexico whether to apply DST in Mexico during 2002. As you may remember from earlier e-mails from me, both president Vicente Fox and rebellion mayor of capital Mexico City Andrés Manuel López Obrador had both lost their rights to impose DST rules upon Mexico locally or globally in court decisions, the court deciding that only Congress of Mexico could take such decisions. However, consulting my local grocery store(!) and my coworkers, they all insisted that a new decision had been made to reinstate US style DST in Mexico, e.g. of 7 months instead of the 5 months as in 2001. Consulting the pages of the government site http://www.conae.gob.mx/ahorro/horaver2001_m1_2002.html confirms this. Sonora as usual is the only state where DST is not applied, matching the way things are on the US side of the border in Arizona. Everything else is status quo compared to 2001 except that DST starts First Sunday of April at 2:00 and ends First Sunday of October at 2:00 (local times). The decree is actually issued by the president Vicente Fox, but stating that "the honorable Congress of the (ed:mexican republic) Union has bestown upon me to publicise the following decree" e.g. the decision was taken by the Congress, not by the president. Concerning the last notification from Rives McDow that Paraguay is changing their DST rules, I presume that this means that Asunción is still on DST until April 7 at 0:00 (local time)? E.g. the decree no. 16350 took effect immediately instead of just modifying the new DST period in Paraguay from September 2002 to April 2003? I found another reference to the decision of the mexican congress on http://www.reforma.com/nacional/articulo/151390/ which was obviously made before the presidential decree was issued. That article also surprisingly suggests a change for the state of Durango from GMT-6 to GMT-7 (except when applying DST) just as states California South, Chihuahua, Nayarit and Sinaloa, but the presidential decree on http://www.conae.gob.mx/ahorro/horaver2001_m1_2002.html doesn't confirm that, so I presume for now it was a journalist's mistake. http://www.terra.com.mx/noticias/articulo/084527/ also mentions the specific votes in the Congress of Mexico, with 295 in favor and 177 votes against the DST decision. 11 blank votes.

The decree is actually issued by the president Vicente Fox, but stating that "the honorable Congress of the (ed:mexican republic) Union has bestown upon me to publicise the following decree" e.g. the decision was taken by the Congress, not by the president. Concerning the last notification from Rives McDow that Paraguay is changing their DST rules, I presume that this means that Asunción is still on DST until April 7 at 0:00 (local time)? E.g. the decree no. 16350 took effect immediately instead of just modifying the new DST period in Paraguay from September 2002 to April 2003?

Hi Arthur, Assume the command "zic -d foo filename" with an input "filename" containing Link this /bar/that All this is certainly foolish and doesn't happen when building glibc, but it could happen. The code at the start of the function "dolink(fromfile,tofile)" in zic.c:589ff first builds the paths fromname and toname by prepending "directory" (from the -d option or TZDIR) to fromfile and tofile it they are not already absolute path. Thus the program will try to create a link from "foo/this" to "/bar/that". It was this situation I wanted to catch by requiring a common prefix (at least "/" if fromname and toname are both absolute paths as they should be when zic is used properly). Maybe you were just misled by the wording "common prefix" which may indeed be not entirely apropriate. Note, however, that with my patch and its test for a common prefix an inputline Link sub/this sub/that will create a symlink "sub/this->that" and not "sub/this->../sub/that" as with the original code (always assuming that the hard link fails). regards Peter Breitenlohner <peb(a)mppmu.mpg.de>

I don't (yet) see the need for a common prefix; I'd love it if someone could enlighten me. --ado

The suggested patch relies on the fact that the Makefile does special stuff for "tzlinks" files. Perhaps a comment should be added to the Makefile indicating that any source file containing "Link" lines should be listed in tzlinks. --ado -----Original Message----- From: Paul Eggert [mailto:eggert@twinsun.com] Sent: Tuesday, February 26, 2002 3:33 AM To: peb(a)mppmu.mpg.de Cc: tz(a)elsie.nci.nih.gov Subject: Re: FW: glibc install problem caused by bug in zic (fwd) > From: Peter Breitenlohner [mailto:peb@mppmu.mpg.de] > Sent: Monday, February 25, 2002 4:56 AM > > Bad timing between two instances of zic, where one tried to link to > a file which the other had not yet created. Thanks for the bug report. Here's an untested patch to glibc/timezone/Makefile to fix that timing problem. (Your symlink fix to zic.c is also welcome, but that's a separate problem.) Can you please test this patch? If it works for you, we can submit it to bug-glibc as "the consensus of the tz experts" (all 2 of us :-). 2002-02-25 Paul Eggert <eggert(a)twinsun.com> * timezone/Makefile (tzbases): Move systemv from here...
