This consists of a terrestrial globe which is driven by a clock mechanism contained in the base and makes one complete rotation from west to east in 24 hours.

[edit] How it works

With its aid the local mean solar time at any place on the earth’s surface can be determined by following a line of longitude from the place in question to the equator and reading off the time upon the hour ring which surrounds the equator. The globe is mounted upon an axis inclined at 231/20 to the vertical and the sun would therefore lie always in a horizontal plane passing through the centre of the globe.
