[Zope] Blank Date Field?

[James W. Howe]

Is there some easy way to allow for the storage and display of an 
empty/blank date field?  It seems that you are unable to enter a blank 
value if you defined a property field as storing a date value.  I want to 
be able to store dates in my object, but the date value is optional.

Any tips would be helpful.
