ABSTRACT:
The present invention is a system and method for providing local time to a mobile vehicle. A time information message is received at an in-vehicle telematics unit, which monitors for a time-update trigger event. A time-update message is sent from the telematics unit to a vehicle bus in response to the time-update trigger event. A computer usable medium with suitable computer program code is employed to provide local time to a mobile vehicle.
