LED Backlight 		This clock would be perfect in any office or classroom. This clock featuring Set & Forget® technology is not an Atomic Clock, but the very next best thing. The Set & Forget® feature allows you to set this clock just once and it will change for daylight savings time in both spring and fall. This clock is ideal in locations that an atomic clock won’t work due to signal interference.

The Atomic radio controlled clock is today's time standard in America's homes and offices. Our radio controlled clock synchronizes with the official U.S. time used by the U.S government, including NASA, the military and the White House, guaranteeing the most precise time keeping available.

The Atomic radio controlled clock receives the nation's official and exact time, down to the precise second via radio signal from the U.S. Atomic Clock in Boulder, CO. The atomic clock automatically adjust for Daylight Savings Time changes, if needed.

An atomic clock is a type of clock that uses an atomic resonance frequency standard to feed its counter. Early atomic clocks were masers with attached equipment. Today's best atomic frequency standards (or clocks) are based on absorption spectroscopy of cold atoms in atomic fountains. National standards agencies maintain an accuracy of 10-9 seconds per day (approximately 1 part in 1014), and a precision set by the radio transmitter pumping the maser. The clocks maintain a continuous and stable time scale, International Atomic Time (TAI). For civil time, another time scale is disseminated, Coordinated Universal Time (UTC). UTC is derived from TAI, but synchronized using leap seconds to UT1, which is based on actual rotations of the earth with respect to the mean sun.
