A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By ...

For much of history, we lived happily without clocks, content with a vague understanding of where we were in the day. How, and when, did this change? Take a look.

From Ancient Greece to modern India’s proud atomic clocks, see what’s ticking – and how that’s about to change.

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the ...

For a brief window this month, the official clocks that quietly coordinate the Internet’s heartbeat slipped out of sync. After a power outage hit key servers in Colorado, the National Institute of ...

What the Clock: Internet time servers are a critical part of the infrastructure used by companies and organizations that rely on atomic clocks to keep accurate time. A US agency responsible for ...

The U.S. government calculates the country's official time using more than a dozen atomic clocks at a federal facility northwest of Denver. But when a destructive windstorm knocked out power to the ...

How some of the world’s most precise clocks missed a very small beat. By Mike Ives and Adeel Hassan Time appeared to skip a beat last week when some of the world’s most accurate clocks were affected ...

In advance of hurricane force winds moving into Colorado earlier this week, Xcel Energy preemptively shut off power to protect areas of the state from extreme fire danger. But due to the outage, time ...

When the sun rises on May 18 in the small Norwegian fishing village of Sommarøy, located above the Arctic Circle, it doesn’t set again until July 26. Later in the year, it vanishes from November until ...
