[edit] How it works

The time is shown by the position of the shadow of the tip of the vertical style. There are two sets of hour-lines in the cup: the full curved lines numbered 9 to 24 for reading the time in ‘Italian’ hours, and the broken lines numbered 6 to 12 and 1 to 5 for reading hours a.m. and p.m.
