U.S. Gets New, Hyper-Accurate Atomic Clock
Boulder, Colorado (CNN) - Timekeeping in the United States just got even more exact!
This photo shows the new u-s atomic clock, called NIST -- f-2.
The national institute of standards and technology unveiled the supercomputer Thursday.
This clock is so accurate -- it will lose or gain only one second every 300 million years!
Scientists say this clock is three times more accurate than the f-1, which has been in use since 1999.
The institute will continue operating both clocks for now at its campus in Boulder, Colorado.
The clocks are used for civilian purposes in the United States and its data is shared with the international bureau of weights and measures in Paris.
Both use lasers and atomic particles to measure time.
