No, pickle also comes with an overhead

>>> from datetime import *
>>> import pickle
>>> t = datetime.now()
>>> len(pickle.dumps(t))
70

For the present discussion, DATETIME_DATASIZE is the only relevant number because we are not going to change anything other than the payload layout in the datetime object or its pickle serialization.
