Using the clock command, you can set the current date and clock of the router.

If the router is not yet equipped with a hardware real-time clock, the default clock

real-time clock, the system will read the clock value when booted, and use it for

setting the system time.

When powered off, the routers stop keeping time, so it is necessary to reset the

current date and time for the router in a rigorous application environment.

For related commands, see display clock.

# Set the current date and clock of the router to 0:0:0 Jan. 2nd, 2001.
