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

[Jens Vagelpohl]

Instead of fighting windmills you should change your input form so that 
it minimizes user error. I would put selection widgets for 
day-of-month, month and maybe even year into that form instead of 
allowing people to type in some free-form date.
