Abstract

PURPOSE:To correct information to the reliable information, by storing a time of power failure and shifting the file information from the time of power failure to the time before time change, by the time difference between the time at change and before change, when the time of computer is changed through a CRT man- machine function with the stored time of power failure. CONSTITUTION:At power restoraton, a power failure processing 9 requests the restart of processing to a clock generating circuit 7 and stores the time of power failure stored in the circuit 7 to a power restoration time information 10. The command of change of the computer time is inputted to a processor 2 via a CRT man-machine device 1. A time change processing section 8 receiving this command requests the time change to the circuit 7 and also the file correction to a file correction processing section 15 via operation circuits 11 and 12. Thus, a processing section 15 shifts the file information from the time of power failure to the time change in a process information file group 14 by the time difference of the time change and corrects it into the reliable information.
