View User view
Parameter zone-name: Name of the summer time, a string of 1 to 32 characters. It is case
sensitive.
start-time: Start time, in the format of HH:MM:SS (hours/minutes/seconds). The
zeros in the argument can be omitted except for indicating 0 hours.
start-date: Start date, in the format of MM/DD/YYYY (months/days/years) or
YYYY/MM/DD.
end-time: End time, in the format of HH:MM:SS (hours/minutes/seconds). The
zeros in the argument can be omitted except for indicating 0 hours.
end-date: End date, in the format of MM/DD/YYYY (months/days/years) or
YYYY/MM/DD.
add-time: Time added to the standard time of the device, in the format of
HH:MM:SS (hours/minutes/seconds). The zeros in the argument can be omitted
except for indicating 0 hours.
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:
■ 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.
■ 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.
