The gnomon of a sundial is cut to a certain size depending on the latitude of the sundial's location. If the gnomon is not of the correct size, it can be compensated for by raising or lowering the lower edge of the sundial until all times are accurate. Calibration is fairly simple. Using a precise time measurement, when it is noon, go outside and position the sundial so the shadow of the gnomon is on noon on the sundial. Check it again at 1 pm, and adjust as needed.
