The confirmation, directly from the “Bolivarian Government”, is that the change would take effect on January 1st 2008. If you feel like practicing your Spanish, here’s the reference http://www.gobiernoenlinea.gob.ve/noticias-view/ver_detalles.pag?idNoticia=…

Time Zone Map Database
by Jamie Lin Sept. 11, 2007

Sept. 11, 2007

I am looking for a time zone database to use in C-Programming. The database descriptions are followed: -Text File easy for processing with C -Contain Map Element, instead of Zone-By-Name -Example: have vector lines that represent timezone boundary with the vector vertices in longitude and latitude coordinate. I notice the Olson Database doesn't contain such boundary line element. And I am wondering where I might be able to obtain such database. I would really appriciate if you can provide me with some information. Thank for your time. _________________________________________________________________ Invite your mail contacts to join your friends list with Windows Live Spaces.

W.r.t timezone update for Asia/Choibalsan
by Chenthill Sept. 7, 2007

Sept. 7, 2007

Hi, I am currently updating the timezones for evolution (default mail client for many linux distros) . I have a small doubt with updating timezone for the location Asia/Choibalsan. I see that the offset is +09000 from the olson timezone database (ftp://elsie.nci.nih.gov/pub/) for the standard timezone, but timeanddate.com (http://timeanddate.com/worldclock/results.html?query=Choibalsan) http://www.travelpost.com/AS/Mongolia/Dornod/Choibalsan/7449157 and http://www.timeinside.com/view.jsp?region=Asia&country=Mongolia&city=Choiba… show its +08000 for Choibalsan. Please let me know which would be the right offset for Asia/Choibalsan. thanks in advance, Chenthill.

C#/VB.NET PublicDomain Olson Time Zone Database Implementation
by Kevin Sept. 7, 2007

Sept. 7, 2007

Hi, I created a fully Public Domain .NET library which implements the Olson time zone database for .NET applications. The package is called PublicDomain and the source, binaries, and documentation are available at http://www.codeplex.com/PublicDomain. Olson time zone database support is just one part of a larger package of various pieces of public domain code. The package was written from scratch in C# and includes an objectified form of the olson time zone database (because we all know how fun it is to analyze the raw, obfuscated data). I also created a variety of unit and regression tests. The implementation used to be quite experimental, but now it has gone through a bit of usage and appears to be getting quite solid. I also wrote an article on codeproject discussing a simple use case of using the package (http://www.codeproject.com/useritems/Using_time_zones_in_NET.asp) I would appreciate it if you included a description of this package for those that use .NET, including C#, VB.NET, etc. on the Olson Time zone database home page (http://www.twinsun.com/tz/tz-link.htm) -- using some form of less verbose description than mine above :-). Thanks! Kevin

Egypt timezone change - Clarification

># From Dirk Losch (2007-08-14): ># I received a mail from an airline which says that the daylight ># saving time in Egypt will end in the night of 2007-09-06 to 2007-09-07. ># From Jesper Norgaard Welen (2007-08-15): [The following agree:] ># http://www.nentjes.info/Bill/bill5.htm ># http://www.timeanddate.com/worldclock/city.html?n=53 ># From Paul Eggert (2007-08-17): ># For lack of better info, assume the new rule is first Thursday. >Rule Egypt 2007 max - Sep Thu>=1 23:00s 0 In response to the uncertainty observed on the mailing list and the latest version of the time zonecode regarding Egypt's recent DST change, I would like to confirm that the change is indeed for this year only. Furthermore, it is as of now unknown when DST will end next year. Some MPs are even suggesting to discontinue DST alltogether, so we will have to wait and see. The reason for this year's change (and for the general confusion) is the holy month of Ramadan (in which Muslims fast from dawn to dusk). Due to the Hijri (lunar Islamic calendar) year being 11 days shorter than the year of the Gregorian calendar, Ramadan shifts earlier each year. This year it will be observed September 13 (September is quite hot in Egypt), and the idea is to make fasting easier for workers by shifting business hours one hour out of daytime heat. Consequently, unless discontinued, next DST may end Thursday 28 August 2008.
