Step 2
clock timezone zone hours-offset

Sets the time zone for the router clock.
• clock timezone command should be entered before
the clock is set because it defines the difference
between the system time and UTC.
Note The system time is the time that appears when you
enter the show clock command.
• zone—Name of the time zone to be displayed when
standard time is in effect.
• hours-offset—Difference in hours from UTC.

end
Example:
RP/0//CPU0:router(config-if)# end
Ends the configuration session and returns to EXEC mode.
Step 5

RP/0//CPU0:router# clock set 14:12:00 10 dec
2008
Sets the system software clock.
Step 6
clock update-calendar
Example:
RP/0//CPU0:router# clock update-calendar
Updates the hardware clock (calendar clock) with the new
clock settings.
• It is battery operated and runs continuously, even if the
router is powered off or rebooted.
