<p>PROBLEM TO BE SOLVED: To provide a time correcting device capable of easily correcting the time of the inside clock in a simple constitution for maintaining temporary continuity even when each information processor connected through a network mutually exchanges data by automatically correcting the inside clocks of the information processors, and obtaining a correct time even when each information processor is connected through not only a private line but also a public line network with a master time being a reference. SOLUTION: This time correcting device is provided with a time correction start part 7 for starting time correction with a set time interval, time requesting part 9 connected with a data communication network for requesting and receiving standard time data, and time correcting part 8 for operating the time requesting part 9 based on a start command from the time correction starting part 7, and correcting the time of an inside clock 2 based on the reference time data when it is judged that the received standard time data are delayed and not received.</p> |
