<p>This invention is related to a time conversion clock (the so-called universal clock) and more particularly to a clock which includes a cross belt pulley set having one end connected with a time recording element and having the other end coupled with a universal time zone map such that the operation of the time recording element drive the universal time zone map to rotate counter-clockwise via the cross belt Pulley. Because the driving pulley of the cross belt pulley is arranged in half size of the driven pulley, when the hour hand is driven to rotate for one turn (12 hours), the universal time zone map will be driven to rotate for half turn.</p> |
