Abstract: A relay device includes a device internal clock to indicate time; a memory to store information; a communication unit to transmit and receive a signal including a synchronization signal and a normal signal to and from a master and a slave. Further, there is a retention time processing unit to store synchronization signal information indicating the synchronization signal received by the communication unit in the memory and extract the synchronization signal information from the memory when a retention setting time longer than a first predetermined time elapses from the reception of the synchronization signal by using the time indicated by the device internal clock; and a transmission signal control unit to control the communication unit to stop transmitting the normal signal when the first predetermined time elapses from the reception of the synchronization signal and transmit the synchronization signal indicating the synchronization signal information.
