Earth Might Move 1 Second Back In Time

2024 is already a leap year – and now timekeepers are mulling the idea of a ‘negative leap second’.

According to a report in the scientific journal Nature, timekeepers might need to move clocks back by one second to account for a faster-spinning planet.  The Earth’s rate of rotation has been gradually slowing for thousands of years – leading timekeepers to add occasional ‘leap seconds’ since 1972.  But now that rate might be speeding up, creating a need to ‘subtract time’.

If you could travel back in time by one second, what would you do differently?
