Hi everyone,

Assuming sender and receiver are synchronous, I want to measure the time
interval between two events: namely, Send.sendDone() event of a packet at
the sender and Receive.receive() event of the packet at the receiver.
Initially I decided to put timestamp of Send.sendDone() event in the packet
and timestamp Receive.receive() event at the receiver, the interval could be
obtained by the difference of the two timestamps. However, packet payload is
loaded prior to calling Send.send() thus before Send.sendDone(), it is
impossible to timestamp Send.sendDone() event and place the timestamp in the
packet. Can anyone give me some suggestion on how this may be achieved?
Thanks very much.
