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 80. The meanings of the
parameters in the configuration column are as follows:
1 indicates date-time has been configured with the clock datetime.
■
2 indicates time-zone has been configured with the clock timezone command
■
and the offset time is zone-offset.
3 indicates summer 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.
■
Use the command...
clock datetime time date
clock timezone zone-name { add | minus }
zone-offset
clock summer-time zone-name one-off start-time
start-date end-time end-date add-time
clock summer-time zone-name repeating
start-time start-date end-time end-date add-time
