Version control? Changelog? Good list of regions/paths aligning with US DST changes?
by Bryan J. Smith Jan. 4, 2007

Jan. 4, 2007

I know this is a tall order. Not looking for anyone to fill it either. I can do my own research, so pointers are always recommended. If I've overlooked this info on the TZ page, my apologies, just [re]point me to it. - Is there a version control repository for zoneinfo? - Or a changelog of any corrections/additions? More to the point, I'm looking for a good list of any regions/zoneinfo paths that are aligning their changes with the US DST changes. I noted several were announced in 2006. I hope I'm not the only schmuck out there trying to track this. I'm hoping someone else has such a list, a blog, etc... If not, I might blog myself, even if it's just a tiny subset and focuses only on the US changes (and ripples from it) going into effect for 2007. Even longer story short, I'm tracking a number of embedded solutions and their tzdata (or lackthereof) updates. Just looking for a good authority on any and all tzdata changes since the 2005 legislation for the 2007 change. E.g., Red Hat has several errata for its tzdata package: - RHEA-2005:655-7: USA, Australia, Haiti, Nicaragua ... - RHEA-2006:0213-7: join US DST change, Canada, Indiana/USA ... - RHEA-2006:0277-7: Sri Lanka - RHEA-2006:0745-3: Western Australia DST But embedded developers like Montavista** only released 1 change (possibly not addressing Canada, etc...): - Fix 15446 (2005Nov): NA timezone file to include the latest DST Ultimately I'm trying to come up with a test plan to verify updates for all major financial/trading regions where our equipment runs. I think I can safely ignore the Indiana changes, etc..., and stick with major regions. -- Bryan J.

BTW, I did note this post: http://article.gmane.org/gmane.comp.time.tz/1339 Unfortunately the svn repository doesn't list changes. I'm used to running "svn+trac" myself, which does a good, basic job of showing version-to-version changes. Unfortunately I don't run a public server myself anymore (just not enough time). Thanx again for any assistance, links or pointers anyone can provide! -- Bryan J.

The Bahamas has changed DST rules
by Sue Williams Jan. 2, 2007

Jan. 2, 2007

The Bahamas announced about a month ago that they plan to change their DST rules to sinc with the U.S. starting in 2007. The attached fax was provided by the Bahama Cabinet office. I was also able to find a corresponding newpaper announcement in the Bahama Journal dated 30 October 2006. http://www.jonesbahamas.com/?c=45&a=10412 _____________________________ Susan J Williams Program Director, IBM Globalization Leadership Team, Globalization Requirements _____________________________

And while I can read C at about the level that most 13-year-olds read Hebrew (and for almost exactly the same reasons), I had some difficulty getting through the raw zdump.c code. Any tips for compiling it using MSVC? I'm a little out of my depth here.

Mataveri only airport?
by Jesper Norgaard Welen Dec. 27, 2006

Dec. 27, 2006

Acording to http://en.wikipedia.org/wiki/Easter_Islands the real capital of Easter Island is not Mataveri, but Hanga Roa, where most people of Easter Island live. Mataveri is famous for the Mataveri International Airport. Should we change the capital in the tz database? Luckily the timezone involved is called "Pacific/Easter" so there is no problem with that. It seems that only the explicit use of Mataveri Mean Time MMT and the commentary in the southamerica file is affected. Perhaps the latitude and longitude coordinates in zone.tab.

Chile DST history
by Jesper Norgaard Welen Dec. 26, 2006

Dec. 26, 2006

In 2006o, a number of changes were implemented in the tz database for Chile and Easter Island and the Palmer station. One of the changes follows here: - -7:00 Chile EAS%sT 1982 Mar 13 21:00 # Easter I Time + -7:00 Chile EAS%sT 1982 Jan 18 21:00 # Easter I Time This was based on my data sent earlier, that origins from the page http://www.horaoficial.htm where it says (my translation) * By Supreme Decree No. 61, of 19.th. of January, the decree No. 1.142 of 20.th. October 1980 is modified, assigning the time GMT-6 to the Easter Islands and Salas and Gómez, this way there will be a permanent difference of 2 hours between the Chile mainland and these islands. However, in those times most decrees were issued much before the actual changes took place and I think this would also be the case here. Checking www.astro.com with Mataveri, it shows Easter Island on "6 h west, Daylight Time" on 12.th. of March 1982, but on "6 h west, Standard Time" on 14.th. of March 1982" in my interpretation GMT-6 in both cases, but the first while being on DST. My recommendation is therefore simply to revert this change, and setting the transition time back to 13.th. of March 1982 at 21:00.
