This standard time sundial has an axial gnomon and a flat dial for which the atmospheric refraction and so on are corrected. It is a practical sundial which provides easy reading of the Japanese standard time without corrective diagrams. The designing process of this standard time sundial starting from a normal horizontal sundial is described. As the results of this designing process, Japanese standard time can be read more easily, and manufacturing merits can be obtained.
