FIELD: physics.
SUBSTANCE: according to the invention, the clock consists of a dome and a world map on said done, a fixed clock face with 24-hour marking, a clock mechanism and a light source. The world map surface is made in deformed scale, has 24 meridians and is placed from the pole to the dome which makes one revolution in 24 hours in accordance with rotation of the Earth. The hour is read from the position of the meridian relative the fixed clock face and the minute is read from the position of a model manmade earth satellite which makes one revolution about the clock face in 1 hour. The dome and the model manmade earth satellite are turned by the clock mechanism with automatic actuation and correction of clock rate using the universal time system. The clock has a light source fitted with a shutter which illustrates illumination of the surface of the earth by the sun during the day.
EFFECT: possibility of viewing current local zone time, world and apparent time simultaneously on all time zones of the planet.
