Examples

In the following example, the manual system clock is configured:

RP/0/RP0/CPU0:router# configure

RP/0/RP0/CPU0:router(config)# clock timezone pst -8RP/0/RP0/CPU0:router(config)# commit RP/0/RP0/CPU0:router(config)# end RP/0/RP0/CPU0:router# clock set 14:12:00 10 feb 2004 14:12:00.090 PST Tue Feb 10 2004 RP/0/RP0/CPU0:router# clock update-calendarRP/0/RP0/CPU0:router# show clock

14:12:00.090 PST Tue Feb 10 2004
