Abstract

PURPOSE:To easily recognize the time at site having at time difference by calculating and displaying the time of a communication destination depending on the time data and the time difference data from a private branch exchange. CONSTITUTION:A central control section 14 of the private branch exchange 16 uses a clock circuit 15 to transmit a signal to a multi-functional telephone set 1 via a subscriber control microcomputer 12 and an interface circuit 11 at every fixed time. A telephone set control microcomputer 7 of the telephone set 1 applies the following control. That is, in receiving the time data from the exchange 16, the time data stored so far in the memory 4 is updated. In this case, when a time difference mode key 6 is depressed and the opposite time from the time data and the time difference data in the memory 4 is calculated and the result is displayed on a liquid crystal display device 2 via a liquid display driver 3.
