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 display clock command.
Follow these steps to configure the system time:

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 Table 7. T
he 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.
