assuming local_time is False:
datetime.datetime.strptime(self.time, gpsTimeFormat) will parse the time format string, which is in UTC, and return a datetime object with no timezone info. This naive object will assume that this datetime object was in the local timezone, which is an incorrect assumption--it is in UTC.
Properly adding the tzinfo attribute should prevent the datetime object from being wrong in the local_time = False case.
