<p>The present invention discloses a method and node for time synchronization. The method includes: a first node acquires a source clock signal from a second node, wherein the source clock signal includes a clock (CLK) and time (TIME); the first node recovers, according to the CLK, the CLK in a reference clock by using a physical layer apparatus supporting Ethernet clock restoration on the first node, and determines, according to the TIME, the TIME in the reference clock by using a time clock synchronization protocol; and the first node transmits the reference clock to other nodes connected with it for time synchronization. With the present invention, the accuracy and time of time synchronization are improved, and meanwhile the equipment cost for time synchronization is reduced.</p> |
