ABSTRACT:
A time managing apparatus that manages times clocked by a plurality of timer modules in apparatuses connected to each other on a network. The time managing apparatus has: a holding means for holding event start time information that indicates an event start time at which one or more events should be started by two or more apparatuses on the network; a time requesting means for requesting a timer module to transmit a standard time; a time receiving means for receiving the standard time; a judging means for judging whether the event start time is reached, by comparing the received standard time with the event start time; and an instructing means for instructing the two or more apparatuses to start executing the one or more events when the judging means judges that the event start time is reached.
