FW: Explain field
by Olson, Arthur David (NIH/NCI) [E] May 26, 2009

May 26, 2009

I'm forwarding this message from Francois Rouleau, who is not on the time zone mailing list. Those of you who are on the list, please direct replies appropriately. --ado From: Francois Rouleau [mailto:rouf0007@gmail.com] Sent: Saturday, May 23, 2009 3:17 To: tz(a)elsie.nci.nih.gov Subject: Explain field Could you please explain to me what seem to be a contradiction in the documentation (File: "tzCode2009e\Zic.8.txt") For the Rule part, you say that the field "FROM" ... "Gives the first year in which the rule applies". Then from the example you say that ... "After 1894-06-01 at 00:00 Swiss daylight saving rules (defined with lines beginning with "Rule Swiss") apply"... but the "Rule Swiss" begin in 1940. There is a laps in time here that I don't understand. Maybe should you also update this document to reflect the change in file for Swiss. Thanks Francois Rouleau

proposed time zone package changes (Jordan, coordinates, et al.)
by Arthur David Olson May 18, 2009

May 18, 2009

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 May 17, 2009

May 17, 2009

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)

by Marc Wick May 10, 2009

May 10, 2009

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
by Edwin Groothuis May 7, 2009

May 7, 2009

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
