Assignee: WHELEN ENGINEERING COMPANY, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC G  H  B | IPC H

Claim 0:
1. A synchronization system, comprising:
a first node configured to:
transmit a first synchronization message;
determine a first time at which the first synchronization message is transmitted;
transmit a second synchronization message containing a tx timestamp corresponding to the first time;

a second node configured to:
receive the first synchronization message from the first node;
determine a second time at which the first synchronization message is received and store a rx timestamp corresponding the second time;
receive the second synchronization message from the first node;
determine a current local time at which the second synchronization message is received;
read the tx timestamp in the second synchronization message;
adjust the current local time of the second node by adding a difference between the tx timestamp and the rx timestamp to the current local time; and
setting the adjusted current local time as a global time.
