1.Local solar time and unequal hours on the central disk
At the central disk the hand indicates Central European Time, represented by Roman numerals. At the drawing hereto the little hand indicates about 2:20 p.m..
Between the curved golden lines the little sun indicates the time advanced between sunrise and sunset in a distribution of 12 hours, represented in Arabic numerals, known as the 'unequal hours' (in winter short hours - at the inner circle - and in summer long hours - at the outer circle). At the drawing hereto: the end of the nineth hour.
The little sun is situated always at the edge of the zodiacal ring and therefore moves up and down on the hand. The central golden circle indicates the place where the little sun is located at the beginnning of spring and autumn; day and night are then equally long.
At the start of the day ORTUS (sunrise) is mentioned, at the end OCASUS (sunset). The period before sunrise is indicated as AURORA
The clock would have to indicate the local solar time as before.
It was originally set to mean solar time and from time tot time it was manually adjusted to correct the Equation of Time.
