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 displays the system
time relative to Coordinated Universal Time (UTC). The system internally keeps time in UTC, so this
command is used only for display purposes and when the time is manually set.
