Displaying the System Clock
The system clock is determined by the commands
clock datetime

and
clock
summer-time
. If these three commands are not configured, the
display clock
command displays the

column are as follows:
z

clock datetime
command.
z
2 indicates time-zone has been configured with the
clock timezone
command and the offset time
is
zone-offset.
z
3 indicates daylight saving time has been configured with the
clock summer-time
command and
the offset time is
summer-offset.
z
[1] indicates the
clock datetime
command is an optional configuration.
