Salutations, This currently does not exist. You can file a Feature Request <https://code.google.com/p/googleappengine/issues/entry?template=Feature%20request> to add that functionality. In the mean time I would look at this link <https://cloud.google.com/appengine/docs/python/ndb/properties#Date_and_Time>, specifically:
