[Zope] Changing Python's Date/Time Input Format

[Julian Clark]

Hi All.
I've got a minor issue with a form which takes a date and returns the string
date.
I'm wanting the input format to be able to accept any of dd-mm-yy, dd mon
year, dd/mm/yyyy.
Currently, it works for dd mon year, but it handles other input as mm/dd/yy.
(which is kind-of un-natural for those using this form)

how should I modify this python script...

today=DateTime(input)
return today.strftime("%d %B %Y")

... to alert Zope that the incoming string will be always in the order of dd
mm yyyy?


This is the traceback when the first tuple is not a valid month.
