Abstract
Disclosed are time synchronization methods for domains based on time information of a vehicle. A time synchronization method performed by a first end node belonging to a first domain of a vehicle includes: receiving a first frame including time information from the vehicle; changing the first end node to a grand master node of the first domain when the time information indicates a time of a universal time domain; and synchronizing a time of the grand master node with the time of the universal time domain.
