The present invention is made with the aim of performing time correction appropriately, regarding an electronic device that corrects its device side time with a time correction information supplied from outside the device. This is achieved by the electronic device (mobile terminal device 2) that corrects its device side time with a time correction information supplied from outside the device, comprising a reception section (wireless reception section 8) that receives the time correction information; and a time correction section (processor 6) that 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. The device further comprises a retention section (memory section 4) that retains the time correction information in order to perform time correction later at the right time. Moreover, computing is performed such that a time span (ΔT, from the instant when the time correction information is received until the instant when the time correction takes place) is added to the supplied time (correction time Tx) in order to obtain the true time (fixed time Ty).
