This is not an inspirational invention but a practical technique. One way to show both ST and DST is to mark the numbers for the hours on the solstice declination lines. When the declination is negative (fall and winter) read standard times. When the declination is positive (spring and summer) read the daylight savings times. This works reasonably well with the switch between standard and daylight savings time being near the equinoxes. You should also build in the longitude correction and an analemma for the eqt correction. Then anyone using the dial could check their watch and comment that the dial was showing the correct time. We all know better. The clocks are wrong. Where I live the clocks try to tell me that it is 1:40 in the afternoon when the sun is due south and at its highest altitude. Ridiculous. Everyone knows that this time is high noon. However I do use clock time when I am headed to the airport to catch a flight. Roger Bailey Walking Shadow Designs N 51 W 115
