Not sure if this is an issue or not, but different datetime64 objects can
be set for different units:
A straight-out comparison of the values as int64 would likely drop the
units, correct? On second thought, though, I guess all datetime64's in a
numpy array would all have the same units, so it shouldn't matter, right?
Just thinking aloud.
