• The data received (a timestamp) in the message is returned in the reply together with an additional 

timestamp. The timestamp is 32 bits of milliseconds since midnight UT. The Originate timestamp is the 
time the sender last touched the message before sending it, the Receive timestamp is the time the 
echoer first touched it on receipt, and the Transmit timestamp is the time the echoer last touched the 
message on sending it.

• Using this command without specifying a request or reply will enable, disable, or set the minimum 

packet gap for both types.

• The timestamp ICMP messages can also be enabled, disabled, and modified using the 

command. See the 

 command information on the type and code for the timestamp ICMP 

messages.
