“We don’t actually use it as a clock. It doesn’t have hands, it doesn’t tell time. What we use it for is to calibrate how fast or slow, more reliable or less accurate clocks are,” said Project Leader Steve Jefferts. “If they’re running fast we can tell they’re running fast. If they’re slow, they’re slow and they can correct for that.”
