Abstract
A clock comprises a dial comprising two or more positions. Each position has an associated time value and the associated time values of the two or more positions increase in a first clock direction around the dial. An indicator provided in combination with the dial indicates a position on the dial with respect to the two or more markings that represents a time. An actuator provides a motive force to move the indicator from one position to another position on the dial under the control of a controller so that the indicator transitions from a first time to a later second time by moving the indicator in a second clock direction opposite the first clock direction around the dial. The clock can comprise one or more indicators, actuators, and sensors for sensing the position of each indicator. Indicators can be clock hands, for example minute, hour, or second hands.
