As I understand these are Ulf> just names and should consist of alphabetic characters only. Hm, perhaps. My understanding is/was that some names are recognized (such as CET for central europe or PST for pacific standard time). These maps to (the equivalent of) GMT+1 (for CET). Ie. I thought we had a synctactic requirement (must start with a letter and be at least three letters long) and a semantic (must belong to this particular set). If a function such as mktime() encounters something it cannot parse it wil just assume GMT. If this is correct, why not just use "GMT" rather than "STD" and "DST"? -- Christian
