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.
