 The default Admin form for a DateTimeField seems to be a split form, with
 separate inputs for both the Date and Time segments. If one provides a
 Date, but no Time, the form produces a value of 'None' and raises no
 ValidationErrors.

 I would expect at least a ValidationError indicating that one must provide
 both a Date and a Time. There is already one thrown if no values at all
 are provided.

 I would imaging this could involve setting "require_all_fields=True" on
 the SplitDateTimeField, however I am not sure.

 I hit this because I have a custom validation applied in my model's
 clean() method (datetime_1 <= datetime_2). This is also called in my
 model's save() method (self.full_clean()). When, using the admin
 interface, I only specify a Date and no Time, I get an error because one,
 or both, of my datetimes are None.
