How I have done it:

1. Submit your date as a string.
2. Create a Python Script to convert a string to a DateTime object. This 
could be as easy as 'return DateTime(str)', which will understand a 
great number of formats. But I think the format you want will be 
understood as the US mm/dd/[yy]yy, so you may have to do a little work. 
See Zope Help > API Reference > DateTime in the Zope Help System.
3. In whatever the form is submitted to call above script and store the 
results. This property can then be used as a DateTime in display: 
'<dtml-var "timeProp.ISO()">

You could also have your script return a canonical string or a floating 
point number representation of the time, if you'd rather store that.

Or you could use a Python Script to preprocess your REQUEST and convert 
your string to something DateTime understands (ISO) and then hand it to 
a method that stores it in a 'date' property.
