Time synchronization is performed between the vehicle-mounted device and another device that is another vehicle-mounted device based on a data propagation delay time between the vehicle-mounted device and the other device. The vehicle-mounted device includes: a processing unit configured to receive, from the other device, request information that requests time information used for updating the propagation delay time, and transmit the time information to the other device; and a detection unit configured to detect an abnormality related to time synchronization, and acquire information regarding the detected abnormality.
