If you enable the option, you can program the Start and End dates from the pull-down
calendar box and then set the time at which the DST takes effect and ends. The time to
be adjusted is to be programmed in "hh mm" format.
When the current time matches the `Starting time', the unit adds the `hours and
minutes to adjust' value to the current time. When the current time matches the
`Ending time', the unit sets the clock back by the `hours and minutes to adjust' value.
