Patent ID: 8335132

Claim:
A system, comprising: an input configured to receive home information for an electronic device; a calibration module configured to calibrate the electronic device to a home time zone corresponding to the home information, wherein calibrating comprises determining a threshold time value for messages to be transmitted to and received from a home location associated with the home information and generating a time zone database based on the home time zone, and labeling each time zone in the time zone database with a label based on an offset in time from the home time zone; a transceiver module configured to transmit a message to the home location at a predetermined interval and receive a return message from the home location, wherein a time value corresponding to time of message transmission to and from the home location is determined; and a processor module configured to determine that the electronic device is within the home time zone in the event the time value is equal to or lesser than the threshold time value, determine that the electronic device is in a new time zone in the event the time value is greater than the threshold value, and calculate the new time zone based on the time value and the time zone database.
