TELLING THE WORLD THE TIME
In a vault in the oldest part of Greenwich Observatory, where three foot walls help to preserve it from changes of temperature and climate, is the famous clock which gives the world its standard time. In appearance it resembles a metal shell-case surmounted by a glass dome through which the delicate mechanism can be seen. This clock is a “master clock" in more than one sense, for it has no strenuous work to do. Its purpose is merely to provide the “brains" of the time recorder. Another instrument, situated elsewhere in the observatory, performs the more strenuous task of operating the pendulum and working the complicated dials which indicate Mean lime. The master clock records “sidereal” or “star” time and by moans of electrical impulses, regulates the secondary timepiece. The clock is capable of recording the time to the onc-hun-dredth part of a second.
