Abstract
Provided is a synchronization system comprising a first synchronization device and a second synchronization device which carry out synchronization processing by transmitting and receiving synchronization packets in accordance with a synchronization protocol and which synchronize the times thereof. The first synchronization device, which corresponds to a slave device, notifies an abnormality to the second synchronization device when an abnormality related to time synchronization processing is detected. The second synchronization device, which corresponds to a master device, increases the interval during which synchronization is performed as the length of time during which an abnormality notification is not received increases.
