Every second matters… or does it?
Tap title to read story
Every second matters – or does it? The way we keep time is set for a shake‑up. Scientists voted to move to continuous UTC, ending leap seconds as Earth’s spin speeds up. The shift, slated for May twentieth, two thousand twenty‑seven, could avert risky negative leap seconds. Since 1972, a leap second has been added twenty‑seven times to keep UTC in sync with astronomical time. Earth’s irregular spin has begun to speed up, meaning a future removal of a second would be required. A 2024 Nature study warned that software systems have never had to go back in time, posing potential catastrophic risks. An international meeting in Paris on October fifteenth, two thousand twenty‑four, approved the resolution to switch to continuous UTC, adjusting only when an hour difference occurs.
