II. Displaying the system clock
The system clock is displayed by system time stamp, which is the same as that
displayed by the display clock command. 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 summer 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.
