A method for time synchronization that includes sending, by a master node, synchronization time information to a slave node through a section overhead, adjusting, by the slave node, a time of the slave node to achieve time synchronization according to the synchronization time information carried in the received section overhead. A system, a master node, and a slave node for time synchronization are also provided. With the disclosure, the synchronization time information is not affected by tributary pointer adjustment and no phase transient occurs when the coding signal of the synchronization time information is transmitted. As a result, the precision of time synchronization is improved.
