@bkbinthecity@wakelys@wendyfrost@sangwann I had to look for this word; gnomon (no-mon) the shadow casting part of a sundial. This is the gnomon of the millennial sundial off the Esplanade. The two buckets are point-point cones with a hole The shadow of the cones fixed through the mast marks the sun time. When the sun crosses the meridian, the line of true north marked on the paving surface, a small circle of light through the cones indicates not only the time but also the date. copied from a website about sundials. Thank you everybody, for the comments and especially the Fav. Very much appreciated.
