IP TCP TIMESTAMP

ip tcp-timestamp

Overview Use this command to enable TCP timestamp responses.
Use the no variant of this command to disable TCP timestamp responses.
You may wish to disable timestamp responses because TCP timestamps may allow
other parties to remotely calculate the system uptime and boot time of the device
and the device's clock. To prevent this information leaking to potential attackers,
we recommend you disable TCP timestamps on the device, unless you need to use
them.
