CLOCK DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a clock device capable of indicating time with high reliability of time renewal and flexibility. SOLUTION: A clock device 1 is provided on a vehicle having a navigation device and GPS time information B is extracted out of GPS information signal input from a GPS antenna 12 by a data analyzer circuit 16 provided in a GPS receiver 14 and an off-set value A is set by the operation of an input device 20. An indicated time data C renewed based on the GPS time information B by a time indication process which an operation circuit 34 provided in a processing circuit 32 executes is corrected using the off-set value A and the indicated time data C is indicated on a time indication device 40 to indicate time. Therefore, with the time device 1 of the example embodiment, the indication time can be renewed at a constant period and the indicated time can be forwarded or delayed as a user wants.
