Abstract
A device having: one or more processors for determining an elapsed time since a correction of a calculated date and time; estimate a degree of deviation included in the calculated date and time, based on the elapsed time; and in response to estimating the degree of deviation to be equal to or smaller than a predetermined range, execute a method by which the one or more processors: generate an expected code sequence of a code sequence to be received from a satellite; control a satellite radio wave receiver to receive the code sequence; determine whether there is a match between the expected code sequence and the code sequence; in response to determining that there is a match, obtain a present date and time information represented by the expected code sequence; and correct the calculated date and time, based on the present date and time information obtained.
