Classification: CPC G  H  B | IPC H

Claim 18:
19. The system of claim 18, further comprising:
another node configured to:
receive the period pulse signal;
trigger another internal timer upon the rising edge of the pulse signal;
determine a third time at which the another internal timer is triggered;
store another trigger timestamp corresponding to the third time;
receive the synchronization message;
determine another current local time at which the synchronization message is received;
read the tx timestamp in the synchronization message;
adjust the another current local time of the another node by adding another difference between the tx timestamp and the another trigger timestamp; and
setting the another adjusted current local time as another global time;

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