PURPOSE:To account the execution time having less converting errors by providing a reading setting means to set the machine clock to the memory and a means to integer-multiply the time slice time for the machine clock. CONSTITUTION:By the operation of an operator, a reading setting means 3 executes the initial program loading and executes the initial setting of the system from a processor 2. Next, a job A is inputted and a task control block 12 is generated. At such a time, a time accounting means 4 uses a time slice remaining time area 122, an execution time area 123 and a clock constant area 11, calculates a machine clock number M and converts to an integer M'. By the integer value M' and the constant area 11, a time slice time T' is calculated, set to a time slice time area 121 and the generation of the task control block 12 is completed. Thus, the program and data of the job A are loaded and the task A is started.
