Description

Description Digital clock time calibration system and digital clock with time calibration function

The present invention is a system in which time calibration information is referred from a personal computer based on standard time on the Internet, and the time of a digital clock is automatically calibrated based on the time calibration information. Also, after calibrating the time of the internal clock of the personal computer based on the standard time on the Internet, the personal computer speaks the time calibration information, and the time of the digital clock that receives it is automatically calibrated. Thus, the present invention relates to a digital clock time calibration system and a digital clock with a time calibration function that can easily and reliably adjust the display time of the digital clock to the standard time of each region. Background art

Not only digital clocks, but also all clocks, even if the time is set once, an error always occurs some time after that. Therefore, the clock is provided with a time configuration function for time calibration (time adjustment). In the case of a digital clock, the time can be calibrated usually by operating switches and buttons. Conventionally, time calibration of digital clocks has the following problems.

1. Normally, when calibrating the time, the user can operate the button switch for time calibration while listening to the time signal provided by telephone, radio, television, etc. It is extremely difficult, and these operations are delayed by a few seconds from the time signal. In the case of an analog clock, a delay of about a few seconds is not a concern, but in the case of a digital clock in which the number of seconds is specified by a number, a delay of a few seconds is clearly recognized, so it is very disturbing. May be. In particular, some digital clocks display the time in units of 1/10 seconds, and in such cases, the delay in comma units is even more of a concern.

2. Radio and television time signals are used in mountain areas, buildings, underground, etc. where radio waves cannot be received. Because it is not possible, the time cannot be calibrated to those time signals. Also, even in places where radio waves can be received, the provision of a time signal by radio or television is not performed several times a day, and the time signal is sometimes changed from day to day, making it difficult to use.

3. The general time signal provided by telephone, radio, television, etc., is in units of one second to several seconds, so it is not possible to perform accurate time calibration in units of 10 seconds.

4. The button switch for time calibration provided on digital watches is generally small and difficult to operate, especially for wristwatches.

5. Recent digital clocks not only display the current time, but also display time around the world by switching time zones, display dates, and sound alarms at set times. It has various functions. However, in order to use these functions, it is necessary to set and calibrate the date, set the alarm time, and so on. Is often not used. In particular, as the number of functions increases, the setting operation becomes complicated, and it becomes more difficult to use these functions.

6. In Japan, the UK, Germany, and some parts of the United States, there are dedicated time signal broadcasts, but they are not available in these specific places, cannot be used, cannot respond to time zone switching, etc. However, it is difficult to incorporate a radio wave receiving circuit (for example, a radio) for receiving a time signal broadcast into a watch, especially a wristwatch.
