Parameters
zone-name: Name of the daylight saving 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

Description
Use the clock summer-time one-off command to adopt daylight saving time from the start-time of the
start-date to the end-time of the end-date. Daylight saving 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 daylight saving time.
By default, daylight saving time is configured on the device, and the universal time coordinated (UTC)
time zone is applied.
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 daylight saving 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.
