Now pickling of the datetime.datetime objects is implemented with __reduce_ex__. __reduce__ is not defined in datetime.datetime and is inherited from

>>> datetime.datetime.__reduce_ex__
<method '__reduce_ex__' of 'datetime.datetime' objects>
>>> datetime.datetime.__reduce__
<method '__reduce__' of '' objects>

__reduce_ex__ has higher priority and is called instead of __reduce__. It is weird that __reduce_ex__ and __reduce__ are not consistent. __reduce__ should be defined as

    def __reduce__(self):
        return self.__reduce_ex__(2)

or just

    __reduce__ = object.__reduce__

Other way is to define __reduce_ex__ instead of __reduce__ in
