Patent ID: 7359288

Claim:
A clock having a microcontroller, a display and a time base generator producing a time reference, comprising: an electromechanical interface connecting a computer setting means directly to the microcontroller for uploading a basic data set comprising at least time of day data associated with a specific geographical region to the microcontroller subsequent to manufacture of the clock; memory cooperating with the microcontroller, said memory storing the basic data set associated with a specific-geographic region; and a power supply connected to the microcontroller for powering the clock; said power supply having a battery for providing continuous power so the function of the microcontroller and the time base generator are ensured during transport of the clock; and said microcontroller using the time reference of the time base generator to update the time during transport of the clock wherein, upon connecting the power supply to power, the microcontroller causes the display of the clock to show at least the current time in the specific geographic region.
