DateTime doesn't like None value :

>>> from DateTime import DateTime
>>> DateTime(None)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "DateTime/DateTime.py", line 1557, in __repr__
    return '%s(\'%s\')' % (self.__class__.__name__,str(self))
  File "DateTime/DateTime.py", line 1561, in __str__
    y,m,d   =self._year,self._month,self._day
  File "DateTime/DateTime.py", line 1056, in __getattr__
    raise AttributeError, name
AttributeError: _year
