About Atomic Clocks

Atomic Clocks

Imagine the immeasurable convenience of a clock that sets itself, is so accurate it meets N.Y.S.E. trading standards, and self-adjusts for daylight savings time.

‘ATOMIC’ clocks synchronize themselves via radio waves broadcast from the US Atomic clock in Colorado--one of the most accurate timekeeping devices on the planet.

Therefore the ‘Atomic’ clock is always set to the exact time that NASA, the National Weather Service, and NOAA (National Oceanic Atmospheric Association) use to monitor official activities. These radio waves can be received anywhere within the continental US.

You'll never again guess at the time when you choose an ‘Atomic’ travel clock, jumbo display wall clock, or indoor/ outdoor temperature clock--they all have the same accuracy to ten billionths of a second per day.

‘Atomic’ clocks have already gained a significant share of the market on clocks in both Europe and Japan, and are quickly gaining popularity in the U.S.

How They Work

The international standard for timekeeping and the official national timepiece, the US atomic clock is accurate to ten billionths of a second per day.

This clock, operated by the National Institute of Standards and Technology (NIST) in Fort Collins, Colorado, is an electronic device that measures time by counting cesium atom oscillations. Cesium atomic clocks are extremely stable and are unaffected by factors such as temperature, pressure, or humidity.

Using a low frequency radio transmission from NIST, the U.S. Atomic clock sends an accurate time signal across the continental united states . These atomic clocks are electronically tuned to the WWVB time signal, which is the very same frequency that is utilized by radio and T.V. Stations , railroads , and NASA.

Recent boosts to the signal strength have provided for improved reception, allowing these timepieces to work in your home or office.

Atomic Clock Features

• Automatically sets itself to the correct time and date by receiving and decoding the NIST radio signal with an internal receiver.
  
  
• This ensures daily accuracy to ten billionths of a second per day by refreshing the signal several time a day.
  
  
• Automatically adjusts for Daylight saving time
  
  
• Digital clocks display hour, minutes, seconds, day of the week month and date.
  
  
• User-selected time zone for any where in the US.
  
  
• Electro Luminescent ‘blueglow’ backlight provides excellent night viewing
  
  
• Snooze Alarm
