Manually Setting the Router Clock

Generally, if the system is synchronized by a valid outside timing mechanism, such as a Network Time Protocol (NTP) or VINES clock source, you need not set the software clock. Use the clock set command for initial configuration or if a network time source is not available.

The clock timezone command should be entered before the clock is set because it defines the difference between the system time and Coordinated Universal Time (UTC). When you set the time, you set the system time, and the router uses the clock timezone command setting to translate that time to UTC. The system internally keeps time in UTC. When you enter the show clock command, the router displays the system time.

To manually set the router clock, complete the following steps:

SUMMARY STEPS

1.configure

2.clock timezone zone hours-offset

3.commit

4.end

5.clock set hh:mm:ss dd mm yyyy

6.clock update-calendar

7.show clock
