Greetings from Kirkkonummi (32km from Helsinki), The correct DST rule (in POSIX TZ syntax) for Finland has been at least since 2002 EET-02:00EEST-03:00,M3.5.0/03:00,M10.5.0/04:00 Notice that in there the zone change times are represented in the local time of the zone which is current at the moment when the change shall take place - i.e. both local times actually refer to 01:00 GMT. I guess Finland used this rule already several years before the common EU directive officially harmonized the DST rules all around EU from 2002 onwards. The EU directive can be found here... http://europa.eu.int/eur-lex/pri/en/oj/dat/2001/l_031/l_03120010202en0021002... I will let you know, if I find more precise info about when Finland actually adopted the current DST rule. Cheers, // jau .--- ..- -.- -.- .- .- .-.-.- ..- -.- -.- --- -. . -. / Jukka A.
