Displaying the system clock
The system clock is decided 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 shown in Table 1-1 . The meanings of the parameters in the configuration column
are as follows:
z
1 indicates date-time has been configured with the clock datetime .
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.
z
The default system clock is 2005/1/1 1:00:00 in the example.
