[QingLong <qinglong@Bolizm.ihep.su>] Ufa timezone.
Thanks for the input. I forward your patch with this mail to the appropriate people. I'm only using the work in glibc. ---------------. drepper at gnu.org ,-. 1325 Chesapeake Terrace Ulrich Drepper \ ,-------------------' \ Sunnyvale, CA 94089 USA Cygnus Solutions `--' drepper at cygnus.com `------------------------
Date: Fri, 9 Oct 1998 08:04:45 +0400 From: QingLong <qinglong@Bolizm.ihep.su> Please add timezone for Ufa. It's just like Asia/Yekaterinburg timezone except that Ufa is located in EUROPE. This is an interesting case, but the Theory file says that tz's general rule here is: If all the clocks in a country's region have agreed since 1970, don't bother to include more than one location even if subregions' clocks disagreed before 1970. Otherwise these tables would become annoyingly large. Shanks (1995) writes that Ufa disagreed with Yekaterinburg before 1924, but that doesn't make the 1970 cut. If we modified the above rule to partition time zone regions by continent as well as by country, then there would need to be other entries besides Ufa. For example, Kazakhstan extends into Europe, so it'd need another entry. Similarly for Egypt in Asia, and perhaps even Moscow's time zone in Asia. I don't see how these extra entries would be useful for tz's intended purpose.

OTOH, we made a precedent with Istambul:
From europe: Link Europe/Istanbul Asia/Istanbul # Istanbul is in both continents.
I know the case of Istambul (as a city) is very uncommon ;-). But I also know that the main part of Turkey is in Asia, so Turkishs in Ankara will be very upset to set theirs clocks to Europe/Istambul... I do not know how big is Ufa (and the relative size of European part of this time zone relative to the Asian part), but that may be a point to consider (i.e. is it the same as Egypt, or the same as Turkey, to be excessive?) Bottom line: unless the Asian part of Yekateriburg is larger than 10 millions inhabitants (arbitrary limit), I consider we should avoid adding this link. Also, Mr Qinglong, please note you can easily customize your own configuration by compiling (using zic) the following source: #%/usr/bin/zic Link Asia/Yekaterinburg Europe/Ufa Quite convenient, isn't it?
