Here's another one for the list, trawled off SF: patch #1118748 (http://python.org/sf/1118748). It proposes to add the ability to add/subtract time and timedelta objects.

And one last patch: #1100942 (http://python.org/sf/1100942), which would add a strptime() constructor for the date and time classes.
