Hello, I want to use French date formats. Here is what I have understood so far about international date formats. If anything is wrong, please say so. I use Zope 2.0.1. I'll write up an howto to summarize the story. 1) OK, if I want to enter the edit time for an objet, I just enter <dtml-var bobobase_modification_time> The result is a long time stamp in GMT format. Eg. : 1999/10/22 13:01:33.059 GMT+1 2) If I want another format, I can use C-style format strings. Eg. : <dtml-var bobobase_modification_time fmt="%d/%m/%Y - %H:%M"> I get the following results : "22/10/1999 - 11:01". Fine, but it's two hours off because it is GMT based. I can also use : <dtml-var "bobobase_modification_time().strftime('%d/%m/%Y - %H:%M')"> Same result. 3) Someone suggested using the "toZone('myTimeZone')" method. Eg.: <dtml-var "bobobase_modification_time().toZone('US/Indiana-Starke').strftime('%d/%m/%Y - %H:%M')">
