A global time reckoning system simultaneously indicates local time and global time. The global time reckoning system can be practiced with standard clock timer drivers, including electromechanical and digital clock motors, in combination with a novel global time system clock face to allow a user to reckon time locally or anywhere on the globe without time zone conversion calculations. The global time system clock face has multiple time scales, at least one of which is driven by the clock drive in cooperation with an hour indicator (e.g., an hour hand). The global time system clock face simultaneously displays global time (relative to any location on the globe) and local time. Additionally, the global time reckoning system, with the appropriate clock timer driver is adaptable to indicate a number of other global time related information, including sunrise / sunset, days of the week, lunar phase and solstices / equinoxes.
