When you ask for a "specification for the IDs", do you mean "which TZIDs are in the Olson database?" or "what syntax is allowed for the TZIDs?"? Either way, I'd say that the FTP site is the stable reference. According to my records that location dates back to April 25, 1992, so it's one of the most stable links on the planet.

proposed tz patch for Argentina, Aaland Islands, etc.
by Paul Eggert June 14, 2004

June 14, 2004

Here's a proposed patch to the tz database. It changes the Argentina data to reflect the June 1 time zone changes reported by Mariano Absatz. This patch also adds support for the new country code AX. To support these things, this patch adds the following Zone or Link lines: America/Rio_Gallegos America/Tucuman Europe/Mariehamn This patch also removes a few broken links from tz-link.htm, and adds a link to the new CLDR localization effort. =================================================================== RCS file: RCS/europe,v retrieving revision 2004.1 retrieving revision 2004.1.0.1 diff -pu -r2004.1 -r2004.1.0.1 --- europe 2004/05/27 16:00:30 2004.1 +++ europe 2004/06/14 07:46:16 2004.1.0.1 @@ -921,6 +921,10 @@ Zone Europe/Helsinki 1:39:52 - LMT 1878 2:00 Finland EE%sT 1981 Mar 29 2:00 2:00 EU EE%sT +# Aaland Is +Link Europe/Helsinki Europe/Mariehamn + + # France # From Ciro Discepolo (2000-12-20): =================================================================== RCS file: RCS/southamerica,v retrieving revision 2004.1 retrieving revision 2004.1.0.1 diff -pu -r2004.1 -r2004.1.0.1 --- southamerica 2004/05/27 16:00:30 2004.1 +++ southamerica 2004/06/14 07:46:16 2004.1.0.1 @@ -155,6 +155,19 @@ Rule Arg 2000 only - Mar Sun>=1 0:00 0 - # </a> says that standard time in Argentina from 1894-10-31 # to 1920-05-01 was -4:16:48.25.

another attempt to change the clocks in the UK
by Peter Ilieve June 9, 2004

June 9, 2004

The summer silly season is almost upon us, and here in the UK some MPs' thoughts are turning again to fiddling with the clocks. Yesterday (8 June) Nigel Beard MP introduced his Lighter Evenings Bill under what is called the ten minute rule. This would advance the clocks in England and Wales by one hour, still keeping summer time. The Scottish Parliament and the Northern Ireland Assembly could make a similar decision for their areas. One of the supporters of this Bill appears to be our old friend John Butterfill (now Sir John Butterfill), who has proposed his own Bill in the past. You can see the Commons order of business that includes this at <http://www.publications.parliament.uk/pa/cm200304/cmagenda/ob040608.htm> and you can read Nigel Beard's speech in Hansard at <http://www.publications.parliament.uk/pa/cm200304/cmhansrd/cm040608/debtext… 08-05.htm#40608-05_head1>. I haven't found the text of the Bill itself yet. It will probably turn up on the Parliament website next week. Ten minute rule Bills have almost no chance of becoming law, so we don't have to worry too much about this yet. Peter Ilieve peter(a)aldie.co.uk
