I've needed to do something similar in the past and used free ntp servers. Of course you need an internet connection: http://ntp.isc.org/bin/view/Servers/NTPPoolServers http://www.nightsong.com/phr/python/setclock.py
You could also have a startup script spawn a thread that stores the time persistently in a shelf object, sleeps for a minute, and checks to see if the current clock time is greater than a minute (+/-sec,) and subtracts the difference. Or even check it against an NTP server if you can. -- http://mail.python.org/mailman/listinfo/python-list
