Abstract
A system for synchronization of multiple clocks in a vehicle network includes a processor that is programmed to synchronize a time follower clock to a primary grand leader clock. The primary grand leader clock is monitored and the time follower clock is synchronized to a standby grand leader clock upon a failure of the primary grand leader clock. The time follower clock is synchronized to the primary grand leader clock if a new ignition cycle has occurred between a failure of the primary grand leader clock and a recovery after failure of the primary grand leader clock. The time follower clock continues to be synchronized to the standby grand leader clock if a new ignition cycle has not occurred between the failure of the primary grand leader clock and the recovery after failure of the primary grand leader clock.
