"The" packet in the sense that you have two tcpdumps, one running on each of the servers, and the time stamp for a 
single given packet captured by the tcpdump on the machine that sent it is about 36 seconds earlier than the time stamp 
for the *exact same* packet captured by the tcpdump on the machine that received it?
