Ion clock has accuracy that outlives the universe

In this case, the new clock uses an ion of aluminum linked to an ion of magnesium, forming what is known as a quantum logic clock. In this, the aluminum ion has a high-frequency, stable "tick." ...

NIST’s ion clock claims record for ‘most accurate in the world’

Researchers at the U.S. National Institute of Standards & Technology (NIST) say they have created the most accurate atomic clock to date — one that can measure time down to the 19th decimal place.
