The earth is twisting and moving on an orbit around the sun. Therefore it seems to us that the sun itselfe moves from east to west across the sky rather constantly. This movement directly determines day and seasonal changings. Using a sundial this movements can be taken to measure the actual time by observing the moving shadows in direction and length.
