Does anyone really know what time it is? Researchers at the University of Colorado – Boulder, in cooperation with the National Institute of Standards and Technology, have developed a clock that keeps setting records for accuracy.
The latest upgrade to the strontium atomic clock developed by JILA means that now the clock will neither gain or lose one second in 15 billion years. The clock is now three times more accurate than it was just one year ago.
JILA, originally known as the Joint Institute for Laboratory Astrophysics, is a joint effort between the University of Colorado Boulder and the National Institute of Standards and Technology.
Precision timekeeping has many applications beyond simple timekeeping, It is used in advanced communications, gravity measurements and exploring correlations between atoms.
One problem with having a clock this accurate is being able to synchronize it with other clocks around the world that are not as accurate. I just have trouble getting all my clocks to read the same time when I change them for daylight savings time!
