Yep.. You could try looking at sys.excepthook --- the interpreter
calls this whenever it hits an uncaught exception.  Maybe at a basic
level:

####
# Put this code somewhere in your app initialisation code.
# Untested!

import sys
import datetime

_excepthook = sys.excepthook
def myExceptHook(type, value, traceback):
    print datetime.datetime.today().strftime('%Y-%m-%d %H:%M:%S')
    _excepthook(type, value, traceback)
sys.excepthook = myExceptHook
####

sys.excepthook is documented here: http://docs.python.org/lib/module-sys.html.

Also check the Python Cookbook
(http://aspn.activestate.com/ASPN/Python/Cookbook/); there are several
recipes dealing with exception handling and printing trackbacks.
