"The Earth doesn't rotate consistently," said Matt Deutch, chief engineer at the NIST radio station."As the earth's rotation slows down in order to keep noon where it should be (at the sun's highest point), we have to make adjustments to keep astrological time in sync with the atomic clocks."
Deutch said the variance in the Earth's rotation is largely due to the moon's gravitational pull on the Earth's oceans.
"The moon's pull on the tide is actually acting as a break on the earth and slowing it down," Deutch said.
The current difference between the ultra-precise atomic clocks and the earth's actual rotational time is 2 to 3 milliseconds per day, according to the NIST.
Another factor according to Deutch is the land mass of the Northern Hemisphere, which accumulates large amounts of snow in the winter and acts as a break.Deutch used the analogy of an ice skater spinning in circles.As the skater moves her arms away from her body, she slows down.

Although the station is now largely automated, it still requires an engineer and three technicians to keep it operating, Deutch said.
"In Fort Collins, the ground is very conductive, which allows for better radio broadcasts," Deutch said.

Matt Deutch, chief engineer at the National Institute of Standards and Technology, explains Friday that a second will be added today to the Time Code Generator to make up for the variance in the Earth's rotation.

Matt Deutch from NIST this week wrote in an email, "I want to assure you that nobody has any intention of discontinuing the WWV/WWVH broadcasts.We are doing a survey as a periodic check (roughly every 15 years) to see how many are using our service and if we are meeting their needs."
