In 1922, the BBC added time "pips' to their broadcast to aid in time synchrony. In the 1850's, a Meridian Circle Telescope was installed in the University of Michigan's Detroit Observatory in Ann Arbor; the time as determined from observation of stars and the Sun was used to coordinate shipping and trains in the Great Lakes region.
