the System Clock
system clock runs from the moment the system starts up and keeps track
of the current date and time based on Coordinated Universal Time (UTC),
also known as Greenwich Mean Time (GMT). The system clock can be set
from a number of sources, and in turn can be used to distribute the
current time through various mechanisms to other systems. To
manually set the system clock, use one of the formats of the clock set
clock set hh:mm:ss day month yyyy
clock set hh:mm:ss month day yyyy
the following example, the system clock is manually set to 1:32 p.m. on
May 12, 2001:
clock set 13:32:00 12 May 2001
