Abstract

A vehicle-mounted apparatus includes: a transmission processing unit configured to perform a transmission process for transmitting, to another vehicle-mounted apparatus, first time synchronization information and second time synchronization information that includes a transmission time at which the first time synchronization information is transmitted, at a predetermined transmission cycle; and a correction unit configured to perform a correction process for correcting the transmission time to be included in the second time synchronization information in a current transmission process, based on a time difference between a current time at the vehicle-mounted apparatus and a previous transmission time, the previous transmission time being the transmission time in the previous transmission process, to a corrected transmission time obtained by adding, to the previous transmission time, the transmission cycle and a value obtained by splitting the time difference.
