Electronic device, time correction method and time correction program thereof

摘要

An electronic device corrects its device side time with a time correction information supplied from outside the device. The electronic device includes a reception section and a time correction section. The reception section receives the time correction information. The time correction section judges whether the information is received during any correction inhibiting periods of the device side time, then either discards the time correction information if it is received during the correction inhibiting periods, or corrects the device side time with the time correction information if it is received other than the correction inhibiting periods.
