[Zope] Formulator - TALES problem

[Michael Dunstan]

Hi Andreas

Try wrapping the DateTime in python script (say with id GetDateTime) 
then accessing that script via acquisition from the form object. For 
example:

   python: form.GetDateTime()

Note that form is the formulator object within ZODB itself. DateTime is 
not an attribute of that ZODB object (not even with with the use of 
acquistion). Python scripts have some objects already floating about in 
the namespace when they are called. DateTime is one such example of an 
object floating about in that namespace.  An implicit import of 
DateTime if you like.
