Operable in synchronism with a current set date and time set by a user, each mobile communication terminal (101-104) has a registering function of registering schedule data (601-604) including a received schedule date and time received from base stations (201-204) and a notifying function of notifying the user of the schedule data when the current set date and time comes to a registered schedule date and time. Each motile communication terminal corrects the received schedule date and time (611) on the basis of a current reference date and time (631) and the current set date and time (801) on receiving the schedule data to obtain the registered schedule date and time (611'). Each mobile communication terminal may receive information indicative of the current reference date and time from the base station with it added to the schedule data.
