proposed time zone package change for Bangladesh
by Arthur David Olson June 17, 2009

June 17, 2009

First a note that tzdata2009i.tar.gz does seem to do the expected thing here on the mother system: Script started on Mon Jun 15 06:34:58 2009 lecserver$ ./zdump -v Asia/Dhaka | grep 2009 Asia/Dhaka Fri Jun 19 17:59:59 2009 UTC = Fri Jun 19 23:59:59 2009 BDT isdst=0 Asia/Dhaka Fri Jun 19 18:00:00 2009 UTC = Sat Jun 20 01:00:00 2009 BDST isdst=1 lecserver$ exit script done on Mon Jun 15 06:35:15 2009 However, given this morning's note about DST starting at 23:00... Finally we've got the official mail regarding DST start time where DST start time is mentioned as Jun 19 2009, 23:00 from BTRC (Bangladesh Telecommunication Regulatory Commission). No DST end date has been announced yet. ...and as a way to both simplify the change and avoid glitches, below find a proposed change to the "asia" file. Feedback both on the usefulness of the change and when to push it is welcome. --ado ------- asia ------- *** /tmp/geta26023 Mon Jun 15 06:44:15 2009 --- /tmp/getb26023 Mon Jun 15 06:44:15 2009 *************** *** 1,5 **** # <pre> ! # @(#)asia 8.34 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)asia 8.35 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 165,173 **** # http://www.timeanddate.com/news/time/bangladesh-daylight-saving-2009.html # </a> ! # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S !

Time zone references in art
by Dave Cantor June 16, 2009

June 16, 2009

A possible addition to tz-art.htm : In the 1946 "A Matter of Life and Death", there is a reference to British Double Summer Time. The time does not play a large part in the plot; it's just a passing reference to the time when one of the characters was supposed to have died (but didn't). The IMDb page is at http://us.imdb.com/title/tt0038733/ Dave Cantor Groton, CT

tzdata2009i - Bangladesh
by Jesper Nørgaard June 15, 2009

June 15, 2009

Bangladesh is applying DST this 20.th.of June. In file tzdata2009i this is the attempt to implement it: Rule Bang 2009 only - Jan 1 0:00 0 - Rule Bang 2009 only - Jun 20 0:00 1:00 S Now that doesn't make sense to me at all. Bangladesh has not had anything close to "DST" since 1951, and then we zero-set DST January 1st. 2009? Then after implementation of DST next Saturday we leave it dangling for the next millenium? Probably this is really just a "typo" for Rule Bang 2010 only - Jan 1 0:00 0 - Rule Bang 2009 only - Jun 20 0:00 1:00 S So Bangladesh leaves DST with year end of 2009, since we have no authoritative information. But this is not a very good guess in my opinion, in fact Steffen Thorsen mentions semi-authoritative information: "On another note, Bangladesh's minister for power said earlier in 2009 that the new timing might continue until the end of September. Timeanddate.com will provide an update on the DST end date when it becomes available." Any guess in the end of September seems better to me, or October 1.st. 2009 at 0:00? ... perhaps this was why Dave Rolsky's test cases were blowing up? :) - Jesper Nørgaard Welen

Hi, I hope i'm not wasting your time. I'm attempting to read the tz database into a c# application, and I'm not sure how to interpret this entry: Zone Australia/Hobart 9:49:16 - LMT 1895 Sep 10:00 - EST 1916 Oct 1 2:00 10:00 1:00 EST 1917 Feb 10:00 Aus EST 1967 10:00 AT EST What is the significance of the "1:00" on the row ending in "1917 Feb". Do I just add this to the 10:00 offset? Thanks, Russell

Understanding the Bangladesh change
by Dave Rolsky June 8, 2009

June 8, 2009

So I went to update my Perl package based on the Olson database this morning, and my tests are blowing up. The problem is that I don't have any code to handle the current Bangladesh situation. If I'm reading the database correctly, it says that there is a change scheduled for 2009, but then there's nothing scheduled for future years. Does that mean that 2010+ are considered unknown and uncalculatable? That seems somewhat problematic. I can't be the only one who expects to be able to use the Olson database to calculate future dates. -dave /*============================================================ http://VegGuide.org http://blog.urth.org Your guide to all that's veg House Absolute(ly Pointless) ============================================================*/

Here's an updated proposed change, reflecting the information from Steffen Thorsen. The "asia" differences are against the current ftpable version.

tzdata mirror no longer found (in tz-link.htm)
by Nathan Stratton Treadway June 5, 2009

June 5, 2009

I noticed that tz-link.htm file currently (as of the version in tzcode2009h.tar.gz) includes a link labeled "smaller HTTP mirror" to http://public.planetmirror.com/pub/timezone However, when I follow that link, the resulting page does not actually contain any timezone-related files -- and in fact after looking around a bit I didn't see any indication that the site still contains a separate mirror for the "upstream" timezone database. (Using the provided search box to search for the word "tzdata" returned only links related to the CentOS mirror that is hosted on the site.) On a separate-but-related topic: I'm not sure how the http://www.twinsun.com/tz/tz-link.htm web page is normally maintained, but I noticed that while the tzcode2009h file's version of the file contains a version stamp of "8.19", the version posted on twinsun is only "8.15". I mention this especially because the page is referenced in many places as the "home URL" of the timezone database project, so it seems like it would be worth trying to keep it as up-to-date as possible.... (The tz-arts.htm file on the twinsun site is also a few revions behind the current tzcode version, for what it's worth.) Thanks.

No DST in Mauritius the coming summer
by Steffen Thorsen June 5, 2009

June 5, 2009

According to several sources, Mauritius will not continue to observe DST the coming summer, which means that the current "max" rules for Mauritius should probably be changed to "only" rules. Some sources, in French: http://www.defimedia.info/news/946/Rashid-Beebeejaun-:-%C2%AB-L%E2%80%99heu… http://lexpress.mu/Story/3398~Beebeejaun---Les-objectifs-d-%C3%A9conomie-d-… Our wrap-up: http://www.timeanddate.com/news/time/mauritius-dst-will-not-repeat.html Regards, Steffen Thorsen - timeanddate.com

New APIs to allow conversion of times in arbitrary zones
by Guy Harris May 26, 2009

May 26, 2009

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 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 !

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).
