<p>PROBLEM TO BE SOLVED: To solve such a problem of a network system that if the OS time managed by an operating system 3 is changed in order to adjust the system time using the network system, the time stamp of a file becomes improper and the reported timer time becomes incorrect. SOLUTION: The network system is provided with a difference value storing means 4 for storing a value of the difference between the system time and the OS time without changing the OS time when the system time is reported to each unit (computer 1) consisting a network, and a system time computing means 5 which adds the value of the difference to the OS time and sends the result back if the system time is required from an application. When the unit becomes a clock master unit, the system time is acquired from the outside of the network by a reference time acquisition means 11 and transmitted to the other units.</p> |
