When the control unit 101 determines that the disconnection request has been received, the process proceeds to step S302. If the control unit 101 determines that the disconnection request has not been received, the process of step S301 is executed again.

(Step S302) The control unit 101 turns off the switch 110 and turns off the power of the wireless communication control unit 111. After that, the process ends.

[Summary of Embodiment]
As described above, the clock system 1 in the present embodiment can point to the symbol “…, Other or O” indicating that the area is another area when the pointer 120 cannot indicate the area name of the current position. ..

Here, according to a clock having a conventional configuration, for example, when the current position is "Seoul" and the pointer cannot point to Seoul, it points to an area having the same time difference as Seoul (for example, Tokyo). As a result, the display of the current position was sometimes substituted. However, according to the clock having such a conventional configuration, even though the current position is Seoul, the clock points to Tokyo, so that the user's current position and the position indicated by the clock do not match, which is annoying to the user. Was occurring.

According to the clock system 1 of the present embodiment, it is possible to reduce the annoyance caused by displaying the area name different from the current position.

It should be noted that all or a part of the functions of each part of the electronic clock 100 or the portable electronic device 200 in the above-described embodiment is recorded by recording a program for realizing these functions on a computer-readable recording medium. It may be realized by loading the program recorded on the medium into a computer system and executing it. The term "computer system" as used herein includes hardware such as an OS and peripheral devices.

Further, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, or a CD-ROM, or a storage unit such as a hard disk built in a computer system. Further, a "computer-readable recording medium" is a communication line for transmitting a program via a network such as the Internet or a communication line such as a telephone line, and dynamically holds the program for a short period of time. It may also include a program that holds a program for a certain period of time, such as a volatile memory inside a computer system that serves as a server or a client in that case. Further, the above-mentioned program may be a program for realizing a part of the above-mentioned functions, and may be a program for realizing the above-mentioned functions in combination with a program already recorded in the computer system.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

For example, in the above-described embodiment, the case where each pointer 120 moves independently by being driven by the corresponding individual stepping motor 122 has been described, but the present invention is not limited to this, and a plurality of pointers 120 are moved by one stepping motor 122. It may move in tandem. For example, the second hand 120A may move independently, and the minute hand 120B and the hour hand 120C may move in conjunction with each other. Alternatively, the hour hand 120C may move independently, and the minute hand 120B and the second hand 120A may move in conjunction with each other.
