Perhaps you should take a closer look :-) The time module is capable of
handling times in all sorts of formats. Specifically, the time module works
with date/time values defined as for Unix, i.e. fractional seconds since the
Unix epoch. These are the values returned by time.time().

Most other things seems to wan to work with tuples, which both gmtime() and
localtime() will produced from fractional seconds. To go back to seconds
from tuples use time.mktime(t) where t is a time tuple.

>>> import time as t
>>> t.time()
1004704959.12
>>> t.localtime(t.time())
(2001, 11, 2, 7, 42, 55, 4, 306, 0)
>>> t.ctime(t.time())
'Fri Nov 02 07:43:29 2001'
>>> t.strftime("%A %B %d %Y %I:%M %p", t.localtime(t.time()))
'Friday November 02 2001 07:47 AM'
>>> t.mktime(t.localtime(t.time())), t.time()
(1004705505.0, 1004705505.3)
>>> t.gmtime(0) # the epoch
(1970, 1, 1, 0, 0, 0, 3, 1, 0)
