Classification: CPC G  H  B | IPC H

Claim 5:
6. The system of claim 1, further comprising:
a third node configured to:
receive the first synchronization message from the first node;
determine a third time at which the first synchronization message is received and store another rx timestamp corresponding to the third time;
receive the second synchronization message from the first node;
determine another current local time at which the second synchronization message is received;
read the tx timestamp in the second synchronization message;
adjust the another current local time of the third node by adding another difference between the tx timestamp and the another rx timestamp; and
set the adjusted another current local time as another global time,

wherein the global time set by the second node is equal to the another global time set by the third node, so that the second node and the third node are synchronized one to another via the first node.
