3 is a flowchart illustrating a time setting method of the time setting system of FIG. 2. 2 and 3, the host 20 is connected to the Internet (see FIG. 1: 15), and receives the standard time of multiple countries from the time server (see FIG. 1: 15) via the Internet 15. . The first memory 28 of the host 20 stores standard times of multiple countries received through the Internet 15. In addition, the first memory 28 stores a program relating to the time setting of the real time clock 39 (S300).

When the program relating to the time setting of the real time clock 39 and the standard times of a plurality of countries are stored in the first memory 28, the user may select the first interface unit 23 and the real time clock system 30 of the host 20. The second interface unit 33 is connected (S302). In addition, the user may input the desired standard time among the standard time of a number of countries and whether the program is in the automatic mode or the manual mode regarding the time setting of the real time clock stored in the first memory 28 through the input unit 25 of the host 20. Select (S304). The selected standard time is time data representing the current standard time by the real time clock 29 of the host 20. In this case, the first control unit 21 may extract the standard times of a plurality of countries stored in the first memory 28 and display them on the first display unit 27 to facilitate selection by the user.

When the automatic mode is selected or the standard time is selected through the input unit 25, the first controller 21 searches the first memory 28 and draws out the program according to the selected standard time and the automatic mode. The first controller 21 transmits the extracted program information to the second controller 31. When the second controller 31 receives the program information, the second controller 31 draws out an instruction code corresponding to the program received from the second memory 38. Accordingly, the first control unit 21 and the second control unit 31 can drive the time setting system according to the program drawn out from the first memory 28.

The first control unit 21 determines whether the automatic mode whether the command input through the input unit 25 is the automatic mode or the manual mode (S306). When the automatic mode is selected through the input unit 25, the first control unit 21 transmits the standard time selected from the first memory 28 through the first interface unit 23 and the second interface unit 33. (31) (S307). The second controller 31 receives the standard time from the second interface 33, and sets the time of the real time clock 39 to the received standard time (S318).

Here, it is preferable that the time of the real time clock 39 to be compared and the selected standard time are not fixed data but shift data whose time calculation is performed by pulses generated at the same time interval. However, the present invention is not limited thereto, and the selected standard time and the time of the real time clock 39 may be extracted and compared with each other.

In addition, the first control unit 21 preferably transmits and displays not only the time of the real time clock 39 but also the selected standard time to the first display unit 27 so that the user can know the comparison result.

If the time of the real time clock 39 and the standard time selected by the user coincide with each other (S312), the first controller 21 erases the selected standard time. As a result, the time of the real time clock 39 remains unchanged. Thus, the time setting method of the real time clock system 30 using the host 20 is finished.

If the time of the real time clock 39 and the standard time selected by the user are different from each other (S312), the first controller 21 waits until a setting command by the user is received through the input unit 25. The first control unit 21 receives a setting command from the input unit 25 (S314).

When the setting command is received from the input unit 25 (S316), the first controller 21 transmits the selected standard time to the second controller 31. The second controller 31 sets the time of the real time clock 39 to the received standard time (S318). Thus, the time setting method of the real time clock system 30 using the host 20 is finished.

The first control unit 21 deletes the selected standard time when a setting incorrect command is received from the input unit 25 or there is no command input for a predetermined time (S316). As a result, the time of the real time clock 39 is maintained as it is, and the time setting method of the real time clock system 30 using the host 20 is finished.
