The API doc is old and outdated:
Both "manage_changeProperties" and "manage_editProperties" call
"_updateProperty". "_updateProperty" has this code:
def _updateProperty(self, id, value):
# Update the value of an existing property. If value
# is a string, an attempt will be made to convert
# the value to the type of the existing property.
self._wrapperCheck(value)
if not self.hasProperty(id):
raise 'Bad Request', 'The property %s does not exist' % id
if type(value)==type(''):
proptype=self.getPropertyType(id) or 'string'
if type_converters.has_key(proptype):
value=type_converters[proptype](value)
self._setPropValue(id, value)
Thus, if you pass a string to "manage_changeProperty" or
"manage_editProperty", it is converted to the correct
type.
A Date property uses the type "DateTime.DateTime".

I checked (Zope 2.2.1):
self.manage_changeProperties(my_prop='2000/9/12')
You can pass any DateTime value, too, e.g.:
self.manage_changeProperties(my_prop= DateTime())

[Zope] set date property from External Method
Hi
I would like to set a property with type 'date' from an External Method.
Because the properties all seem to be saved as a string, in Python I do:
self.prop_datetime = time.strftime('%Y/%m/%d %H:%M:%S.000
GMT+1',time.localtime(time.time()))
This results in a optically (!) correct value like:
2000/09/16 17:49:02.000 GMT+1
However, when I call a document which uses the date, as with:
Zope produces an error:
Zope has encountered an error while publishing this resource.
Error Type: NameError
Error Value: dd
The funny thing is, when I manage the properties and just do a 'save
changes', the error is gone and the date is displayed correctly ...
It seems to me that the date property is not saved as a string after all ?
But what then ? I tried self.prop_datetime = time.localtime(time.time()) and
self.prop_datetime = time.time(); both result in a string representing their
value but none of them results in a date/time value
