The Python datetime module's handling of time zones is completely, entirely deficient -- the tzinfo class is just a skeleton and therefore useless. Install something that will give you fully implemented time zones like at http://pytz.sourceforge.net/ and try again -- pulling a tzinfo from this module and doing datetime_instance.replace(tzinfo=tzinfo_object_for_timezone) on your datetime instance parsed from the string will result in far more predictable behavior and probably get everything behaving as you expect. -- http://mail.python.org/mailman/listinfo/python-list
