A time master instrument includes: a time information transmitting portion that transmits local time information to time slave instruments; a time information response requesting portion that requests that, through unicasting to the time slave instruments, time information be sent back; a time information comparing portion that compares the time information from the time slave instrument and the local time information; and a notifying portion that notifies a user when the time information comparing portion evaluates that there is a discrepancy in time information. A slave instrument includes: a time information setting portion that sets time information transmitted by the time information transmitting portion; a time information acquiring portion that acquires local time information in response to a response request by the time information response requesting portion; and a time information responding portion that sends back, to the time master instrument, time information acquired by the time information acquiring portion.
