Classification: CPC G  H  B | IPC H

Claim 13:
14. A synchronization method, comprising:
transmitting, by a first node, a first synchronization message;
determining, by the first node, a first time at which the first synchronization message is transmitted;
transmitting, by the first node, a second synchronization message containing a tx timestamp corresponding to the first time;
receiving, by a second node, the first synchronization message from the first node;
determining, by the second node, a second time at which the first synchronization message is received;
storing, by the second node, a rx timestamp corresponding the second time;
receiving, by the second node, the second synchronization message from the first node;
determining, by the second node, a current local time at which the second synchronization message is received;
reading, by the second node, the tx timestamp in the second synchronization message;
adjusting, by the second node, the current local time of the second node by adding a difference between the tx timestamp and the rx timestamp; and
setting, by the second node, the adjusted current local time as a global time.
