Earth's changing spin is threatening to toy with our sense of time in an unprecedented way—but only for a second. For the first time in history, world timekeepers may...

A major milestone towards the redefinition of the second has been achieved by scientists at the National Physical Laboratory (NPL) with the first inclusion of a UK optical frequency standard (NPL-Sr1) in the determination of International Atomic Time (TAI).

The worlds timekeepers balance ultra-precise atomic clocks with the irregular spin of our planet to come up with the world clock.

REUTERS/NASA/Handout via Reuters/File Photo Earths 28 fastest days ever recorded happened in 2020. On average, the planet rotated more quickly around its axis last year than it did in previous years.  Scientists who measure the speed of Earths rotation think 2021 may be even faster than 2020. If so, they may need to subtract a second from the year.   As it turns out, 2020 was shorter than previous years – even though it didnt always feel that way.  The 28 fas...

Scientists consider slashing a leap second from time as Earth spins at its fastest in half a century Timekeepers around the world are debating whether to add a negative leap second to time, in a would-be historical first.

Scientists consider slashing a leap second from time as Earth spins at its fastest in half a century Timekeepers around the world are debating whether to add a negative leap second to time, in a would-be historical first. Jan 07, 2021 11:48:51 IST Scientists have now revealed that that Earth is rotating faster than normal and as a result, the length of each day has become slightly shorter than 24 hours. Timekeepers around the world are reportedly debating whether to delete a second from time to...
