Used by NASA to aid in satellite tracking and by the Pentagon to synchronize troop deployment, this full-color moving map shows at a glance what time it is throughout the world. The 15 x 26-inch map revolves within its frame at precisely the same speed as the earths rotation and continuously displays what areas of the earth lie in daylight or darkness. The analog dial system automatically charts the time in the worlds 40 time zones on a 24-hour scale. Backlit by two 15-watt fluorescent tubes, a set of cam-driven, light-diffusing, flexible mylar panels produce an illuminated gray pattern that slowly adjusts with the seasons (and daylight savings time). The map shows the exact global location of daylight and darkness, the duration of daylight/darkness and the moment of sunrise and sunset. A moving calendar displays the date both right and left of the international date line and also day of the week and month. Black laminate exterior finish cleans with soft cloth. Glass panel over map. Aluminum housing. Geochrons time zone map can be updated. Surface brackets included. Plugs into household outlet. UL listed. Instructions included. Overall: 34 1/4 W x 22 3/8 x 5 D. (28 lbs.)
