'Shortest day of 2026' is set to come this month, though this tiny time change in Earth's day may look 'small', how this 'milli-seconds shift' is threatening GPS and satellites

This Sunday, July 26, will be the shortest day of 2026 . However, the difference is so tiny – just 0.65 milliseconds – that no one will notice. This time is less than the blink of an eye, less than the time it takes a camera flash to fire, and life will carry on entirely undisturbed.

The Earth's rotation is altering in ways that are unmatched in at least 3.6 million years, and climate change is the reason.
