A time ball is a now obsolete time signalling device. It consists of a large, painted wooden or metal ball that is dropped at a predetermined time, principally to enable navigators to verify their marine chronometers from their ships offshore. Accurate timekeeping is one means by which longitude can be determined at sea.
