I am still a stupid beginner to Zope, but when I am not completly wrong, then I have found another BUG within ZOPE's DateTime(): (pseudo syntax): enddate=2001/05/04 DateTime().lessThanEqualTo(enddate) results for today (2001/05/04) into FALSE !!! I can only assume that this happens, because the DateTime() returns a date and a time - where enddate is only a date .... Can someone verify this and report the bug to the developers??? Its really important for me!! Thanks Kai -- Institut für Seeverkehrswirtschaft und Logistik http://www.isl.org/ Dipl.-Inform.
