Binary electronics are unfortunately very analog. H and L are just abstractions and simplifications. This is just more "up front" about it.
This is also a fun display of sig figs. You can build a sundial that tries to display to single minutes, but that doesn't mean it'll be accurate unless you have a rather elaborate microcontroller almost continually adjusting the angles from day to day, not to mention daylight savings time. I think if you'd have to adjust the mounting angle thru the day would depend on latitude and month of year.
On the equinox, a quarter of an angular degree is a minute of chronological time. This varies a bit thru the year, and depends on your lattitude too. Ask your local celestial navigation guy. I have just enough experience with celestial navigation and sailboats to know I shouldn't be doing it, or at least I'd have to be super careful if I tried it for real.
