The issue is that the difference between two dates (d) is not itself a date, 
it is an interval.  Python expresses this interval (d) as a floating point 
number representing the number of days between the two dates.  It is trivial 
to convert this to hours, minutes, seconds, fortnights, or whatever you might 
need.  In addition in the python 'datetime' (not Zope's DateTime) module 
there is a timedelta class which extracts the days, seconds, microseconds for 
you.
