Times can be entered digitally or by dragging a point along the hour hand axis at the bottom (needed because of difficulty controlling dragging of a point around a circle!)
The hands on the outer faces can be dragged freely for reference; the hands on the centre faces are controlled by the time.
Times can be advanced in multiples of 1, 5, 10, 15, 20, 30 and 60 minutes.
See the Notes file that comes with the app.
