Displaying the system clock

The system clock 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
clock. If you combine these three commands in different ways, the system clock is displayed in the ways
as shown in 0. The following describes the meanings of the parameters in the configuration column:
• 1 indicates date-time has been configured with the clock datetime command.
2 indicates time-zone has been configured with the clock timezone command and the offset time is
•
zone-offset.
3 indicates daylight saving time has been configured with the clock summer-time command and
•
the offset time is summer-offset.
• [1] indicates the clock datetime command is an optional configuration.
The default system clock is 2005/1/1 1:00:00 in the example.
