Abstract:
A mobile communications terminal, comprising:a terminal input for entering a time revision instruction for a terminal time by a user, said time revision instruction being a specific time deviation or a new selected time desired by the user; a generator in communication with the terminal input for generating a revised time in accordance with the time revision instruction; a first terminal storage portion for storing a reference time; a second terminal storage portion for storing a differential between the time generated by the generator and the reference time stored in the first terminal storage portion; and a controller for correcting a time generated by the generator based on the differential stored in the second terminal storage portion and the reference time stored in the second terminal storage portion; wherein, even for a changing reference time, a constant time differential is maintained with the reference time by comparison with the generator, after the user inputs the specific time deviation or the new selected time, and the revision is repeated with the same specific time differential stored in the second terminal storage portion until another specific time differential or a new selected time is input by the user.
