[Zope] DateTime mess

[Chris Withers]

Hi Jürgen,

Many thanks for even thinking about looking at the DateTime debacle ;)

Well yes, but you don't want to force people to change in an unpleasant 
way. From what I can see, DateTime _should_ just be a lightweight 
wrapper around Python's datetime.datetime to add the extra formatting 
commands, helper methods and zodb persistence.

However, it isn't, and I don't think changing it to be so is the way to go.

What I _would_ like to see is a new package that works with both Zope 3 
and Zope 2 and offers exactly this. We could advocate switching to this, 
with DateTime becoming deprecated and removed in, say, Zope 2.10.

I wonder if Zope 3 has something that meets these needs already? Perhaps 
you could have a dig and find out on zope3-dev at zope.org?

cheers,

Chris
