An in-vehicle network system includes first device and second device configured to send or receive to or from each other, and an intermediate node connected between the first device and the second device, the intermediate node being configured to output buffered messages in a sequence determined by a relative priority scheme. The first device includes a control unit configured to measure a communication delay for each of a plurality of different priority messages, set a delay representative value less than a maximum value of the plurality of communication delays, and adjust time that a time management unit manages, based on time that the first device manages, time that the second device manages, and the delay representative value.
