* Fix GPS that hard code 2080 as the start time. Some GPS chips, such as the AG3335 in T1000e and L96 have a hardcoded time of 2080-01-05 when they start up. To fix that in a way that seems permanent, let's ignore times that are more than 40 years since the firmware was built. We should followup in late 2039 to see if any changes are needed.
