By default the Digital Clock will have DST Setting input, but they are not active. The use of the ‘U’ Command will result in the clock returning “DST Values Not Set!”

You must first enter the settings that are correct for your time-zone using the ‘V’ Command, as described below.

The DST String contains the following components:

1.       Month – A value between 1 and 12;

2.       Week – A value between 1 and 5;

3.       Day – A value between 1 and 7;

4.       Hour – A value between 0 and 24.

The components of the DST String are used twice, once for the DST Start and secondly for the DST End

The DST String is entered in the following format:

V x:x:x:x x:x:x:x

An example of entering this would be:

V 3:5:7:2 10:5:7:2

The Response from the clock would be:

DST Start

Month:= March

Week:= Last

Day:= Sunday

Hour:= 2


Month:= October

Week:= Last

Day:= Sunday

Hour:= 2

A tool to help calculate the DST Settings String can be found here.
