After the above configuration, you can see that the current system time displayed on the
System Time
page is the same for Device A and Device B.
Configuration guidelines
•
A device can act as a server to synchronize the clock of other devices only after its clock has been
synchronized.
If the clock of a server has a stratum level higher than or equal to that of a client’s
clock, the client will not synchronize its clock to the server’s.
•
The synchronization process takes a period of time. Therefore, the clock status may be
unsynchronized
after your configuration. In this case, you can refresh the page to view the clock
status later on.
Configuring the system time in the CLI
The system time is determined by the configured relative time, time zone, and daylight saving time. To
view the system time, use the

System time configuration examples
The system time is determined by the commands
clock datetime
,
clock timezone
and
clock summer-time
.
If these three commands are not configured, the
display clock
command displays the original system time.
If you combine these three commands in different ways, the system time is displayed in the ways as
shown in
. The numbers in the configuration column are described below:
•
1 indicates that the date-time has been configured with the
clock datetime
command.
•
2 indicates that the time-zone has been configured with the
clock timezone
command and the offset
time is
zone-offset.
•
3 indicates that the daylight saving time has been configured with the
clock summer-time
command
and the offset time is
summer-offset.
•
[1] indicates that the
clock datetime
command is optional.
•
The default system time is 2005/1/1 1:00:00 in the example.
