Abstract
A method and system are provided for adjusting a clock time setting in a vehicle. The system includes a global positioning system that is in communication with a vehicle control module and has a memory that stores geographical data corresponding to time settings for regional time zones. The method includes the steps of determining in which of the regional time zones the vehicle is located, detecting a difference between the vehicle clock time setting and the time setting for the regional time zone in which the vehicle is located, adjusting the vehicle clock time setting if the control module is configured to automatically adjust the vehicle clock time setting, and sending a clock adjustment prompt to a vehicle operator interface if the control module is not configured to automatically adjust the vehicle clock time setting.
