I agree with that, but I don't see a problem with having them in the
same module. In my opinion you should get the simple case when you
don't have time zone information added to your datetime objects, and
the robust calculations when you do. The only problem from where I
stand is that today's robust calculations are incorrect.

Documentation could probably be better...
