Hmm... how so? I've always thought it quite nice that when, for example, 
you store the modification time of an object in a DateTime, you can 
safely update it without worrying about the whole object having to be 
repickled when you change it...

Yes, they will, but that's not the point ;-)

Yes, I'd verymuch like to see Zope 2 and 3 end up with the same datetime 
and timezone story, but one that does involve persistence...

cheers,
