PROBLEM TO BE SOLVED: To provide an operation time management device for a prime mover capable of improving reliability of recording of operation time.SOLUTION: In an operation time management device for a prime mover, a plurality of control units 10a, 10b, 10c... are connected with each other by a line 1. Each control unit includes: a communication device 11 for transmitting/receiving information with other control units; a clocking device 16 for clocking operation time of a prime mover; a storage device 13 for storing the clocked operation time; a selection device 14 for selecting whether to set a belonging control unit as a main control unit or to set as a subordinate control unit; and a synchronization device 15 for selecting a synchronization value of the operation time. The synchronization device 15 of the main control unit selects a synchronization value from each operation time excluding an outlier, and outputs the synchronization value to each control unit. The clocking device of each control unit overwrites the synchronization value on the operation time stored in the storage device of the belonging control unit. |
