The clock shows a single time of 8:40 (corrected to GMT), but it is accurate all year round. The analemma of the sundial is the place where the shadow of the nodule symbolizing the Sun falls at the start of school. The size of the analemma is 3350 x 840 mm, cross-section 5 x 50 mm. It is fixed on the facade at a height of 10 metres and the anchors are at the entry points of the Sun into each sign of the zodiac. The analemma is waterjet cut from structural steel and welded, the finish is a metallic sprayed stainless steel. The indicator is the nodus itself - a laminated gold-plated sphere with a diameter of 125 mm. The perpendicular distance of its centre from the facade is 151 cm. It is suspended from a stainless steel cable, which runs in a general position - the cable represents only a structural element lacking any gnomonic function.

=========================================================

Hodiny ukazují jediný cas 8:40 (korigovaný na SEC), zato však po celý rok presne. Analema slunecních hodin je místem, kam v okamžiku zacátku školního vyucování dopadá stín nodu symbolizujícího Slunce. Rozmer analemy je 3350 x 840 mm, prurez 5 x 50 mm. Na fasáde je pripevnena ve výšce 10 metru a kotvy jsou v místech vstupu Slunce do jednotlivých znamení zverokruhu. Analema je vyrezaná vodním paprskem z konstrukcní oceli a svarená, povrchovou úpravu tvorí metalický nástrik nerezu. Ukazatelem je pouze samotný nodus - laminátová pozlacená koule o prumeru 125 mm. Kolmá vzdálenost jeho stredu od fasády je 151 cm. Zavešena je na nerezovém lanku, které probíhá v obecné poloze - lanko predstavuje pouze konstrukcní prvek postrádající jakoukoliv gnómonickou funkci.
Sundial Type: Analemmatic - Vertical gnomon with elliptical dial
