[Zope] How can I import DateTime into a script??

Hi there, I am trying to create an Id based on the time of its creation. since I can not use the Pythons thime module I would like to use a DateTime class. However I stumbled trying to do so. the following code: import DateTime t = DateTime.Time() produces an error Error Type: AttributeError Error Value: Time whereas: from DateTime import Time t = DateTime.Time() produces Error Type: ImportError Error Value: import of "Time" from "DateTime" is unauthorized can anybody tell me how to do it correctly? thanks Robert
