[DE] Diese Sonnenuhr ist keine gewöhnliche Sonnenuhr, sondern eine Präzisionssonnenuhr. Die Besonderheit ist, dass der Schattenwerfer (also das Teil der Sonnenuhr, welches den Schatten wirft, über den dann die Urhzeit abgelesen werden kann) speziell geformt ist, um die eliptische Bahn der Erde um die Sonne auszugleichen. Dadurch ist die Anzeige minutengenau, was bei "normalen" Sonnenuhren nicht der Fall ist.
Die genaue Uhrzeit ist am linken Rand des Schattens abzulesen.


[EN] This sun dial is not a common one, but a precision sun dial. The special thing is, that the part casting the shadow has a special shape, which takes the elliptical orbit of the Earth around the sun under consideration and compensates it. Thus, the time shown on this sun dial is more precise than for common sun dial.
The exact time can be read on the left edge of the casted shadow.
