New atomic clock could be world’s most precise

New atomic clock could be world’s most precise –

The rate of ticking of this timepiece — known informally (and awkwardly) as the ytterbium optical lattice clock — does not change by more than one part in 10^18, Ludlow said. In other words, if there is any variation in how a second is measured, it would be in about the 18th decimal place.

That is an error rate of less than a second every five hundred million years.
