Description
Use the
clock summer-time one-off
command to adopt summer time from the
start-time
of the
start-date
to the
end-time
of the
end-date
. Summer time adds the
add-time
to the current time of the device.
Use the
undo clock summer-time
command to cancel the configuration of the
summer time.
After the configuration takes effect, you can use the
display clock
command to view it.
Besides, the time of the log or debug information is the local time of which the time zone
and summer time have been adjusted.
Note that:
z
The time range from
start-time
in
start-date
to
end-time
in
end-date
must be longer
than one day and shorter than one year. Otherwise, the argument is considered as
invalid and the configuration fails.
z
If the current system time is in the time range specified with this command, the
system time automatically adds “add-time” after the execution of this command.
