That's not a feature, it's a bug.

Use of tz database
by Cheryl Sallen Nov. 19, 2007

Nov. 19, 2007

Dear Messrs Olson and Eggert: This is to request assistance with my research into a suitable time zone database for use in updating commercial data products. Tele Atlas North America, Inc. ("TANA") seeks to improve the content and accuracy of time zone information within its national and global, street centerline, proprietary database. Since your website clearly describes the tz database as a public domain database, I will want to proceed as if there are no restrictions on its commercial use. If restrictions do apply, please respond to that effect. TANA data analysts have reviewed a sample of your files. I am tasked with relaying several technical observations / questions: * Is there a metadata file available? * The purpose of the code is not clear. * Can the code be 'tested'? * Will the code produce a list with state, county, and time zone (as applicable for North America, of course)? * Does your naming convention NOT reference counties' association with time zones? * Updates appear to be released 'as needed'. I believe the most recent was Oct. 1, 2007//version h? Is there an update schedule other than as needed? If the answers to these questions exist elsewhere, kindly point me to them? Your time and attention to my request will be much appreciated. Sincerely, Cheryl Cheryl J.

xmlDate Compiler
by Louis Guindon Nov. 19, 2007

Nov. 19, 2007

Hi, The link for xmlDate complier from Philippe GOETZ is not working anymore. I am refering to this entry "xmlDate contains JavaScript code that parses tz source into an internal object that represents a time zone. It is freely available under the GPL. " on the web page http://www.twinsun.com/tz/tz-link.htm. I am very interested by this tool and wandering if you know the new location or the developer contact information. Regards, Louis Guindon

tzcode2007h.tar.gz - Functions defined with prototypes and C99 features?
by Jonathan Leffler Nov. 7, 2007

Nov. 7, 2007

In the tzcode2007h.tar.gz file, there is (at least) one function that is defined in prototype notation: static time_t hunt(char *name, time_t lot, time_t hit) It seems to me that the code assumes that there is a 64-bit integer type (int_fast64_t (function detzcode64()), though the code goes through some machinations to find a 64-bit integer and doesn't outright assume C99 compliance. Is there actually a good reason not to write the whole library with ISO prototypes? And lose the historically necessary but now unnecessary P macro for declaring functions with (or without) prototypes. Which platform(s) do not provide a C compiler that is capable of handling prototypes? I know of none on the major platforms...Unix, Linux, Windows (though maybe the bundled C compiler on HP-UX is still unaware, but that is intended for linking kernels, not program development). -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

Re: Iran's exact law for re-instating daylight saving
by Paul Schauble Nov. 7, 2007

Nov. 7, 2007

I think there. Is an additional complication here. I believe the Persian calendar begins on the day of the true equinox. This varies over about a 2 day period so there is not a fixed correspondence between Persiam dates and Gregorian. I'm sure I will be corrected if need be. ++PLS ----- Original Message ----- From: Roozbeh Pournader <roozbeh(a)farsiweb.info> To: Paul Eggert <eggert(a)CS.UCLA.EDU> Cc: tz(a)lecserver.nci.nih.gov <tz(a)lecserver.nci.nih.gov> Sent: Wed Nov 07 05:09:15 2007 Subject: Re: Iran's exact law for re-instating daylight saving On Tue, 2007-11-06 at 00:27 -0800, Paul Eggert wrote: > Thanks for the citation.

The law is basically reinstating the 1991 regulation of President Rafsanjani's board of ministers which was canceled by President Ahmadinejad's board of ministers a few days before daylight saving was supposed to come into effect again in 2006. BTW, the funny thing is that Hassan Habibi, the First Vice President that signed the 1991 regulation, and Gholam Ali Haddad-Adel, the Parliament's Speaker who signed the 2007 one, have been the only two presidents of Iranian Academy of Persian Language and Literature since its revival in 1990. Habibi became the Academy's President when it was recreated (while also serving as First Vice President) and was replaced by Haddad-Adel after his term finished. But later, Haddad-Adel resigned from the post when he became the Parliament's Speaker, leading in Habibi filling his original position again. Roozbeh

proposed tz changes for Brazil, Egypt, Iran, Gaza, Venezuela
by Paul Eggert Nov. 7, 2007

Nov. 7, 2007

Here are proposed changes to the tz database for the news items we've accumulated recently: * Brazil will observe DST from 2007-10-14 00:00 to 2008-02-17 00:00. (Thanks to Steffen Thorsen for this.) * Egypt switched earlier than we expected. (Thanks to Dirk Losch and Jesper Norgaard Welen for this.) * Likewise for Gaza. (Thanks to Jesper Norgaard Welen for this.) * Iran will resume DST next year. (Thanks to Jesper Norgaard Welen for this.) * Venezuela is currently planning to change time zones on January 1, to -04:30.

HST vs. HAST
by Bill Seymour Nov. 2, 2007

Nov. 2, 2007

A newbie question that could have an answer similar to the recent question about Australian time zones... I note that Pacific/Honolulu and Pacific/Johnston say HST rather than HAST; but America/Adak says HA%sT. Is there a reason for leaving out the 'A' for Hawaii and Johnston Atoll? Thanks, --Bill Seymour

Saint Barthélemy
by Jesper Norgaard Welen Oct. 27, 2007

Oct. 27, 2007

I think we should include Saint Barthelemy in the tz database, probably in the northamerica file. Currently I don see any mention of it, so the minimum would be to include the island in an appropriate parenthesis for one of the current timezones. The island has a population of 6,852 in the 1999 consensus. The other reason it should be included is that it has its own country code BL, so it should be in the iso3166.tab file. However wikipedia http://en.wikipedia.org/wiki/Saint_Barthelemy and the CIA factbook https://www.cia.gov/library/publications/the-world-factbook/geos/tb.html claim that it uses DST, the first as usual without any detail, while the latter gives the dates starting 20. March and 17. October (for 2007 only?). I have tried to find information on the French-only homepage of the island, but my French skills are definitely not up to the task - perhaps there is no mention of DST in these pages anyhow. The page http://www.st-barths.com/guidepgs/practical.html#10 claims that there is no DST in use in Saint Barthélemy. As usual I welcome any other information that anyone might have to shed light on the possible application of DST on Saint Barthélemy.

FW: Syria DST
by Jesper Norgaard Welen Oct. 27, 2007

Oct. 27, 2007

The sister center ICARDA of my work CIMMYT is confirming that Syria DST will not take place 1.st November at 0:00 o'clock but 1.st November at 24:00 or rather Midnight between Thursday and Friday. This does make more sence than having it between Wednesday and Thursday (two workdays in Syria) since the weekend in Syria is not Saturday and Sunday, but Friday and Saturday. So now it is implemented at midnight of the last workday before weekend. I know this is semi-official information, but that is the best I can do. I hope you will be able to receive the graphics "Winter Time.jpg" if not here is the essential part of the text (it's a scanned letter with ICARDA letterhead): "Winter local time in Syria will be observed at midnight of Thursday 1 November 2007, and the clock will be put back 1 hour."
