While obvious when you look from the inside of the implementation,
this is something that datetime library users will never understand.
That's why over my strong objections, timedelta grew its
total_seconds() method which is nothing else but  x /
timedeta(seconds=1).  After that, I gave up and committed
datetime.timestamp() as a shortcut for (x - EPOCH) /
timedeta(seconds=1).
