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 do not need to 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, follow these steps:
