25 May '15

It's March Madness time for daylight-saving rule changes. Here's a proposed change to the tz database to keep up with the latest political development, which affects time stamps starting March 29: * Latvia and Lithuania will not observe DST, starting this year.

corrected DST data Switzerland 1941 and 1942, final report
by Alois Treindl 25 Aug '11

25 Aug '11

Hello I have researched the DST usage in Switzerland during the 1940ies. As I wrote in an earlier message, I suspected the current tzdata values to be wrong. This is now verified. I have found copies of the original ruling by the Swiss Federal government, in 'Eidgenössische Gesetzessammlung 1941 and 1942' (Swiss federal law collection) and attach GIF copies of the two pages for 1941. DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am. DST began on Monday, 4 May 1942 at 01:00 am DST ended on Monday, 5 Oct 1942 at 02:00 am There was no DST in 1940, I have checked the law collection carefully. It is also indicated by the fact that the 1942 entry in the law collection points back to 1941 as a reference, but no reference to any other years are made. Newspaper articles I have read in the archives on 6 May 1941 reported about the introduction of DST (Sommerzeit in German) during the previous night as an absolute novelty, because this was the first time that such a thing had happened in Switzerland. I have also checked 1916, because one book source (Gabriel, Traite de l'heure dans le monde) claims that Switzerland had DST in 1916. This is false, no official document could be found. Probably Gabriel got misled by references to Germany, which introduced DST in 1916 for the first time. The tzdata rules for Switzerland must be changed to: Rule Swiss 1941 1942 - May Mon>=1 1:00 1:00 S Rule Swiss 1941 1942 - Oct Mon>=1 2:00 0 - The 1940 rules must be deleted. One further detail for Switzerland, which is probably out of scope for most users of tzdata: The zone file Zone Europe/Zurich 0:34:08 - LMT 1848 Sep 12 0:29:44 - BMT 1894 Jun #Bern Mean Time 1:00 Swiss CE%sT 1981 1:00 EU CE%sT describes all of Switzerland correctly, with the exception of the Cantone Geneve (Geneva, Genf). Between 1848 and 1894 Geneve did not follow Bern Mean Time but kept its own local mean time. To represent this, an extra zone would be needed. Two GIF files are attached. best regards Alois -- || Alois Treindl, Astrodienst AG, mailto:alois@astro.com || Zollikon/Zurich, Switzerland || Free astrological charts at http://www.astro.com/ || SWISS EPHEMERIS Free Edition at http://www.astro.com/swisseph/

New APIs to allow conversion of times in arbitrary zones
by Guy Harris 26 May '09

26 May '09

For the benefit of programs such as world clocks and any other program that would need to convert times in an arbitrary zone specified by a TZ setting, I've added some APIs to load time zone information for a specified zone, free that time zone information, and convert between time_t and struct tm in specified zones: zoneinfo_t loadzone(const char *zonename) Attempts to allocate and fill in a structure to hold information for the time zone specified by "zonename"; returns a pointer to the time zone information on success and NULL on failure. void freezone(zoneinfo_t zoneinfo) Frees zone information returned by loadzone(). struct tm *localtime_zr(const time *clock, struct tm *result, zoneinfo_t zoneinfo) Like localtime_r(), but does the conversion in the time zone specified by zoneinfo. time_t mktime_z(struct tm *timeptr) Like mktime(), but does the conversion in the time zone specified by zoneinfo. zoneinfo_t is implemented, internally, as a pointer to a "struct state", but it's opaque to the callers. I'm not committed to any of the names, or the order of the arguments; for example, "loadzone()" doesn't necessarily load information from a file - it might parse a POSIX-style TZ string - so that might not be the right name. The new functions are declared in an "xtime.h" public header (the name was inspired by the BSD "xlocale.h" header that declares functions such as printf_l() which take a locale information pointer as an argument). See the attached patch and "xtime.h" file.

proposed time zone package changes (Jordan, coordinates, et al.)
by Arthur David Olson 18 May '09

18 May '09

To celebrate Norwegian Independence Day here are proposed changes to the time zone package: * "public domain" statements are added to a number of files * Instances of "=3D" are changed to "=" in the "africa" and "southamerica" files. * The start of DST in Jordan from 2002 forward is changed from 0:00 on the last Friday of the month to 24:00 on the last Thursday. * Four sets of latitute/longitude are correct in the "zone.tab" file (with thanks to Marc Wick). * Commentary is added to the "australasia" file regarding DST in South Australia (no changes to the rules). If no problems are found, these changes should appear in the ftp directory on 2009-05-26 (a day later than usual since the 25th is a United States holiday). --ado diff -c old/Makefile new/Makefile *** old/Makefile Mon Mar 23 09:37:49 2009 --- new/Makefile Sun May 17 14:44:05 2009 *************** *** 1,4 **** ! # @(#)Makefile 8.7 # Change the line below for your time zone (after finding the zone you want in # the time zone files, or adding it to a time zone file). --- 1,7 ---- ! # <pre> ! # @(#)Makefile 8.8 ! # This file is in the public domain, so clarified as of ! # 2009-05-17 by Arthur David Olson. # Change the line below for your time zone (after finding the zone you want in # the time zone files, or adding it to a time zone file). diff -c old/README new/README *** old/README Mon Mar 23 09:37:49 2009 --- new/README Sun May 17 14:44:05 2009 *************** *** 1,4 **** ! @(#)README 8.2 "What time is it?" -- Richard Deacon as The King "Any time you want it to be." -- Frank Baxter as The Scientist --- 1,6 ---- ! @(#)README 8.3 !

Jakarta is Indonesia West Time Not Central Time
by Martin Pitt 17 May '09

17 May '09

Hello tzdata developers, https://launchpad.net/bugs/365215 reported that tzdata currently puts Jakarta into WIT (Indonesia Central Time), but it actually belongs into WIB (Indonesia West Time). It seems that http://www.timeanddate.com/worldclock/timezone.html?n=108 also gets this wrong (perhaps it's using tzdata?) The official website is currently down, however this url still accessible from google cache: http://209.85.173.132/search?q=cache:JBpW5TryxxAJ:www.bmg.go.id/dataDetail.… but the real url is: http://www.bmg.go.id/dataDetail.bmg?Jenis=Teks&IDS=7452470612766189439&IDD=… The document states that GMT +7 (jakarta time) is Waktu Indonesia Barat (WIB), GMT +8 is Waktu Indonesia Tengah (WITA), and GMT +9 is Waktu Indonesia Timur (WIT). Thank you! Martin -- Martin Pitt | http://www.piware.de Ubuntu Developer (www.ubuntu.com) | Debian Developer (www.debian.org)

Hi Four timezones have coordinates in the zone.tab file that are far away from the real place. I have listed the correct lat/lng below. Could someone please modify the file? Africa/Gaborone: correct to -2439+02555 (the current -2545+02555 is in South Africa) Pacific/Noumea: correct to -2216+16627 Pacific/Tongatapu: correct to -2110-17510 Europe/Vatican: correct to +415408+0122711 (the current +4154+01227 is in Italy) Thanks. Best Marc

License for the tzdata information

07 May '09

For all the years I have never worried about this, but today I got an email in my mailbox asking me "Since this is vendor imported data, we would like to register under which license this data is distributed.". Unfortunately I got not much info from Wikipedia, the tzdata or the tzcode files. The tzcode says "This code is in the public domain", but the tzdata doesn't have it, just a "This information is by no means authoritative". So... is there a license under which the tzdata is distributed? Edwin

In which of four zones should lastThu 24:00 be used
by Olson, Arthur David (NIH/NCI) [E] 06 May '09

06 May '09

Responses on the mailing list indicate that use of 24:00 in timezone source files is the way to go where appropriate. The question now is: where is where? There are four places currently using a "lastFri 0:00" rule for the start of DST now and into the future: Script started on Tue May 05 09:43:53 2009 lecserver$ grep -i max.*lastfri.*0:00.*1:00 * africa:Rule Egypt 1995 max - Apr lastFri 0:00s 1:00 S asia:Rule Jordan 2002 max - Mar lastFri 0:00s 1:00 S asia:Rule Palestine 2009 max - Mar lastFri 0:00 1:00 S asia:Rule Syria 2009 max - Mar lastFri 0:00 1:00 S lecserver$ exit script done on Tue May 05 09:44:14 2009 We've seen a report that Jordan should really be "...Mar lastThu 24:00..." What of the other three areas? (Alas, Egypt is the only one of the three where a look at old newspapers might help.) --ado
