How accurate is the atomic clock in Boulder Colorado?
How accurate is the atomic clock in Boulder Colorado?
It loses just one second every 300 million years. If your Timex runs a few minutes slow, the worst thing that might happen is that you miss your bus.
Can you visit the atomic clock in Boulder?
See the Atomic Clock at NIST Boulder, Colorado, is the official timekeeper for the United States. Unfortunately, the National Institutes of Standards and Technology (or NIST) no longer offers widespread public tours, citing security reasons.
What is the atomic clock in Boulder Colorado?
cesium fountain clock
NIST-F1 is a cesium fountain clock, a type of atomic clock, in the National Institute of Standards and Technology (NIST) in Boulder, Colorado, and serves as the United States’ primary time and frequency standard.
Can you visit the atomic clock?
Due to staffing and security requirements, NIST no longer offers tours for the general public.
Where is the most accurate atomic clock?
The world’s most precise clock is found in the United States. The clock was built by the National Institute of Standard and Technology together with the University of Colorado, Boulder. The clock is so precise no second is lost over the entire age of the Universe.

Where can I find an atomic fountain clock?
Similar atomic fountain clocks, with comparable accuracy, are operated by other time and frequency laboratories, such as the Paris Observatory, the National Physical Laboratory (NPL) in the United Kingdom and the Physikalisch-Technische Bundesanstalt in Germany. As of 2013, the clock’s uncertainty was about 3.1 × 10 −16.
Where do I get my atomic clock signal?
A radio controlled clock sold in North America is permanently set to receive and process an atomic clock synchronization signal broadcast from WWVB in Boulder, Colorado. Most atomic digital clocks have an icon in the display that indicates if the atomic clock signal is being received properly from WWVB (usually a radio tower icon).
Where was the NIST-F1 cesium fountain atomic clock developed?
NIST-F1, the nation’s primary time and frequency standard, is a cesium fountain atomic clock developed at the NIST laboratories in Boulder, Colorado. NIST-F1 contributes to the international group of atomic clocks that define Coordinated Universal Time (UTC), the official world time.
How does a radio controlled atomic clock work?
