I think Antoine meant "timedeltas".  Having a date infinity necessitates an
infinite timedelta to represent a difference between a finite and an
infinite date.

While we cannot add dates, it is still a valid question what the result of
subtracting an infinite date from itself should be.  If we make it
timedelta(0) then date.inf is not that different from date.max.
