clock timezone zone hours-offset
Example:
RP/0/RSP0/CPU0:router(config)# clock timezone
pst -8
Sets the time zone for the router clock.
• The 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
type 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.

configuration.

RP/0/RSP0/CPU0:router(config-if)# end
Ends the configuration session and returns to EXEC mode.

Sets the system software clock.
Step 6
clock update-calendar
Example:
RP/0/RSP0/CPU0:router# clock update-calendar
Updates the hardware clock (calendar clock) with the new
clock settings.
• The hardware clock is battery operated and runs
continuously, even if the router is powered off or
rebooted.
