Yes, but the sun dial will be very full of information -- not anywhere as simple as the sundial depicted and quite difficult to use and enjoy. I live in Houston, Texas. Solar time differs universal coordinated time by anywhere from 4 minutes to 35 minutes throughout the year, with the greatest "spread" between early November and early February when the earth's orbit is moving through the far side of the elliptical (ie: winter). Additionally, you'd have to make adjustments for your longitudinal variance in the time zone.
