Just one. The empty interval is a singleton and I want it to be smaller
than any other interval.
UTC_ZERO = datetime.datetime.utcfromtimestamp(0)
EMPTY_INTERVAL = Interval(UTC_ZERO, UTC_ZERO) # TODO: how generalize
this for any ordered type?
Probably I could use Interval(None, None), and refactor my code.
The other problem would be __str__ and formatting, but that is easy to
generalize.

Operators changed to what you have suggested. (Also added ^ and
__contains__)
Thank you!
