Hello! I recently asked the same question in the german Zope mailing list zope-de@yahoogroups.de but did not get any answers. Maybe someone can help me here. How can I force Zope to accept german date format (dd.mm.yyyy) in an input field? If I enter 13.07.2002, the field becomes 2002/07/13 correctly (clear, there isn't 13th month), however, when I enter 12.07.2002, Zope makes 2002/12/07. When I enter an invalid date like 31.02.2002 (2002/02/31) Zope hangs and does not response (browser never get's ready). I use Zope 2.5.1 with Python 2.1.3 on a linux2 box. I already tried the command line parameter -L "de_DE", but without success. The problem appears when I preset the value of a date property with the german date format like this: <input type="text" name="Datum:date" size="35" value="<dtml-var ZopeTime fmt="%d.%m.%Y %H:%M">"> Any hints? Regards, Juergen
