Hi, I am trying to conduct an experiment that determines message-propagation delays, processor speed differences, and clock synchronization errors between 2 computers. I am running the experiment using both TCP/IP and UDP connections. I just wondered, if I could get the system time when a message is received, I could possibly calculate the message progapation delay. However, I am not clear how to get the time stamp whenever a message is received. Could someone help me with this?
