Yikes! How about time.gmtime().tm_year, etc, instead of all the calls
to strftime() and int()? And you might want to put the value of
time.gmtime() in a variable so you always use the same value, just in
case someone runs your program on New Year's Eve at midnight.

You might also want to look at the datetime module, in particular
datetime.timedelta.
