Use datetime.datetime objects and subtract one from the other:
http://docs.python.org/lib/datetime-datetime.html

import datetime
time0 = datetime.datetime(2005, 5, 6, 23, 3, 44)
time1 = datetime.datetime(2005, 5, 7, 3, 3, 44)

td = time1 - time0
print 'time difference is %s seconds' % td


The "td" object will be a datetime.timedelta object.
