Sundial plaque, Horniman Museum

On the conservatory TQ3473 : Conservatory, Horniman Museum. (below the sundial TQ3473 : Sundial, Horniman Museum). Since the Earth's orbit is elliptical and its axis of rotation is not perpendicular to its orbit, the day length varies, and sundial time varies from clock time.
