Abstract

PURPOSE:To prevent the generation of a big time shift by detecting a TOD (time of day) clock having the time shift larger than a specific time shift out of those TOD clocks of each subsystem of a composite system, and setting the time of the detected TOD clock. CONSTITUTION:The TOD clocks of each subsystem of a composite system are read out by a reading means 31 at a specific time point. A comparison means 32 decides whether the read time is correct or not. In such a case, said time is compared with the time of a specific TOD clock of the system 30. While other TOD clocks are compared with the time pointed by the specified TOD clock. Then the TOD clocks set out of a specific time shift are set by a setting means 33. As a result, all TOD clocks of the system 30 point the times within the specific time shift. Thus it is possible to avoid the conflict of the start and end time points of jobs in the system as a whole.
