One more thing: In the U.S., the time-zone boundaries usually or at least nearly always follow state boundaries. That results in some extremes that result in people being out unnecessarily in the dark. So, instead, the time-zone boundaries should be meridians. The intended time-zone middle-meridians would be the middle-meridians, and the boundaries would be the meridians 7.5 degrees east and west of that middle-meridian.
In the U.S., the middle-meridians should and would be 75, 90, 105, and 120 west longitude. Europe, too, would surely benefit from meridians instead of country-boundaries as time-zone boundaries. Oh, and just one more thing: Why would you want a sundial to tell clock-time??? If you want clock-time, put up a clock. Sundials give a time that a clock doesn't give: Local True Solar Time. LTST is of interest. ...aesthetic and practical. More meaningful in every way, in fact, other than business and other interpersonal affairs, for which Standard-Time is convenient. Of course LTST is also called French Houirs. If you want a sundial to tell other kinds of time, Babylonian hours &/or Co-Italian hours are of interest, for their own sake, in addition to having practical relevance.
