As a physicist in the National Institute of Standards and Technology (NIST) Time and Frequency Division, I have worked in the general area of operating atomic clocks and using output signals from them to distribute time and frequency information for more than 40 years. I am also a Fellow at JILA, an institute operated jointly by NIST and the University of Colorado Boulder, and I teach in the physics department of the university.
I came to Boulder in 1967 as a post-doc at JILA. I joined NIST when it was still the National Bureau of Standards in 1969, and I was initially a physicist in the Radio Standards Physics Division. This division was engaged in several research projects that used lasers whose wavelengths were stabilized by adjusting them to match the wavelengths naturally absorbed by an atom or molecule.

Scientists consider slashing a leap second from time as Earth spins at its fastest in half a century Timekeepers around the world are debating whether to add a negative leap second to time, in a would-be historical first. FP Trending January 07, 2021 11:28:19 IST Earth.
Scientists have now revealed that that Earth is rotating faster than normal and as a result, the length of each day has become slightly shorter than 24 hours. Timekeepers around the world are reportedly debating whether to delete a second from time to account for the change and bring back precision to the timeline with respect to the rotation of the Earth. As per the report, the addition of the negative leap second has never been done before.
