Earlier this week, the National Institute of Standards and Technology (NIST) officially launched an atomic clock that is three times as accurate as the one used today to do everything from synchronize GPS systems to time-stamp financial transactions.

The previous atomic clock, called NIST-F1, was launched in 1999. It was accurate to within plus or minus one second over the course of 100 million years. The newly launched atomic clock, called NIST-F2, is accurate to within plus or minus one second over 300 million years.
