The Royal Observatory is famous for supplying Greenwich Mean Time. From 1833, astronomers made a daily signal to mariners in the Thames at 1 p.m. (1300 hrs) by raising and dropping the time-ball on Flamsteed House. In 1852 electrical technology enabled them to send the time to the nation by telegraph. Visitors to Greenwich Park could also get the time, without disturbing the astronomers, from the Shepherd Gate Clock outside of the observatory.
The Shepherd Gate Clock is a slave dial that originally received electrical impulses from the master clock within Flamsteed House.
As the time-ball drops, air is compressed in a cylinder below, to cushion its descent to the base of the mast.
