hi all, every object inside Zope (i.e. of the ZODB) has got its own modification time. If you have access to an object inside a product, for example via "my_obj = self.restrictedTraverse(obj_path)", you can get a human readable version of that modification time with "my_obj.bobobase_modification_time()", calling that certain method everyone knows. is it possible to get access to the modification time attribute of the object directly ? what about "my_obj._p_mtime" ? how can one set / update / change ? thanks, Andreas Hoelzl
