clock summer-time one-off
Use clock summer-time one-off 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 standard time of the device.
Use undo clock summer-time to cancel the configuration of the daylight saving time.
Syntax

Parameters
zone-name: Specifies a daylight saving time schedule by a zone name, a case-sensitive string of 1 to 32
characters.
start-time: Specifies a start time, in the hh:mm:ss format. Zeros can be omitted, unless you specify
00:00:00.
start-date: Specifies a start date, in the MM/DD/YYYY or YYYY/MM/DD format.
end-time: Specifies an end time, in the hh:mm:ss format. Zeros can be omitted, unless you specify
00:00:00.
end-date: Specifies an end date, in the MM/DD/YYYY or YYYY/MM/DD format.
add-time: Specifies a time to be added to the standard time of the device, in the hh:mm:ss format. Zeros
can be omitted, unless you specify 00:00:00.
Usage guidelines
The interval between start-time start-date and end-time end-date must be longer than one day and shorter
than one year. If the current system time is in the specified daylight saving days, the add-time value
automatically adds to the system time.
To verify the setting, use the display clock command.
The timestamps in system messages are adjusted in reference to the time zone and daylight saving
schedule.
Examples
# Set the system time ahead one hour for the period between 06:00:00 on 08/01/2011 and 06:00:00
on 09/01/2011.
