Others reading this with more experience manipulating timezones please
reply. This is completely out of the realm of my experience, but since I
pointed Wayne here from the webmaster mailing list I felt I should respond.
What I've written is based solely on reading a bit of the current time
module documentation and peeking at the time module source
(ever-so-briefly).

Python's timezone code is reliant on the functions provided by your system's
libc routines. Starting in Python 2.3 if your system has a working tzset()
function in libc the time module exposes a tzset() function which you can
use to change the rules used by your system. If your system's timezone
information hasn't been updated I imagine you could coax the correct
behavior out of your application with tzset(). I suggest you read the
relevant documentation
http://docs.python.org/dev/lib/module-time.html
before contemplating upgrading from 2.1 to something more recent and/or
modifying your application to use tzset(). Given the minimal amount of time
between now and Sunday morning I suspect your best chance of correct
operation will be to have the correct timezone tables installed on your
computer.
