[PATCH0/1] Propose new zone for Crozet Islands
by Antoine Leca April 18, 2013

April 18, 2013

Hi Paul, I also have a patch submitted some time ago which seems to have been forgotten. I reworked it to match git workflow. For easier work, I have also put it as a new branch on my github repository: https://github.com/antoineL/tz/commits/crozet About the content from the former discussion <http://mm.icann.org/pipermail/tz/2012-May/017804.html> that I scrapped from the commit message, there were a reference to an official reference (in French) that can be read at the bottom of page 30 of <http://www.taaf.fr/IMG/pdf/guidehivernant2011.pdf< (taaf.fr is the official site of the territory), which spells the rules using the old GMT+4 moniker, and as a reference to the Europe/Paris rules. Since that URL is likely to change (!) you might want to refer to http://www.taaf.fr instead; or just drop it completely, which was my option. Antoine

Abreviation(s) for Daylight Saving Time in Australia [SEC=UNCLASSIFIED]
by Peter Stagg April 17, 2013

April 17, 2013

I have one simple question that I'm hoping to get a straight forward answer to. Has enough been done by Timothy, Myself and other contributors to convince the coordinators that the current situation where Daylight Saving Time (for Australian time zones) is abbreviated as ST = Summer Time is in error and should be changed?

Complete list of IANA time zone abbreviations
by Tobias Conradi April 16, 2013

April 16, 2013

Is a complete list of IANA time zone abbreviations available in the WWW? I found: * http://en.wikipedia.org/wiki/List_of_time_zone_abbreviations * http://www.timeanddate.com/library/abbreviations/timezones/ * http://www.timegenie.com/timezones.php All list ACDT which, as of today, is not an IANA abbreviation, so these listings are not what I am looking for. -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com

Suggesting an ISO standard for time zone identification - possible replacement of IANA abbreviations
by Tobias Conradi April 16, 2013

April 16, 2013

Dear Mr. Carpenter, this email is send to you, because you are listed as the secretary for the "TC 46/SC 9 Identification and description". Maybe you can forward it to the relevant office or tell me where else I can email to. I suggest that the ISO creates an ISO standard for time zone identification. Current abbreviations in the IANA time zone database are ambiguous, e.g. IST may refer to Israel Standard Time or India Standard Time. The standard could be used in the IANA time zone database and projects that collect time zone related data, e.g. laws and translations of names. Since time zone law is country related one could look whether ISO 3166 can be used. The IANA time zone database has the stated aim of being correct for all regions in the world after the year 1970. Although the earliest ISO 3166 country code standard on the ISO website is ISO 3166:1981, web search for ISO 3166 1974 gives several hits claiming the first publication was in 1974. If there have been countries between 1970 and 1974 that have no ISO 3166 code one can use codes from the user-assigned code space. So the first two letters might be ISO 3166-1 alpha-2 country code based. But I suggest checking whether the alpha-3 codes or numeric codes are a better fit. Further letters may then mark regions inside a country and special restricted time shifts, e.g. daylight saving time. Such a structured set could look like: AUEDT - Australia Eastern Daylight saving Time AUCDT - United States Central Daylight saving Time AUWDT - Australia Western Daylight saving Time EUEDT - EU Eastern Daylight saving Time EUCDT - EU Central Daylight saving Time EUWDT - EU Western Daylight saving Time IDEST - Indonesia Eastern Standard Time IDCST - Indonesia Central Standard Time IDWST - Indonesia Western Standard Time USEDT - United States Eastern Daylight saving Time USCDT - United States Central Daylight saving Time USPDT - United States Pacific Daylight saving Time Kind regards Tobias Conradi -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com

Patch use LHDT/LHST/LHHDT since HD HS DD DS are common practice
by Tobias Conradi April 12, 2013

April 12, 2013

Patch australasia.20130411.withLHHDT is linked from http://anna.info/wiki/ANNA_time_zone_database - I don't link to the actual location, because that may change. And I don't email, because I don't know what the email client does with the file. The patch includes AEST/AEDT ACST/ACDT AWST/AWDT CWST/CWDT LHDT/LHST/LHHDT -------- The bom.gov.au-patch introduces new syntax, which for itself might be fine, but this new syntax is less informative than the established one and might be seen as deterioration to the whole database. No single use of single "D" for non-1:00 saving has been found by me. There is one single "D" in a LHDT but there it referred to a 1:00 saving. Be consistent, apply common practice established by the maintainers and use: HD 0:30 LHHDT Australia/Lord_Howe For non 1:00 DST offsets the database contains: DD 2:00 NDDT America/St_Johns IDDT Asia/Jerusalem DS 2:00 MDST - Moscow Double Summer Time, BDST - British Double Summer Time HD 0:30 CHDT America/Belize CHDT EHDT America/Santo_Domingo HS 0:30 UYHST America/Montevideo IHST Asia/Colombo CKHST Pacific/Rarotonga HS 0:20 GHST Africa/Accra -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com/
