Estimates indicate that the first Tuesday of August will be about 1.25 milliseconds shorter than standard. Earth's average rotation is 24 hours, but various factors cause fluctuations in its speed. Recent studies suggest that melting polar ice caps could be contributing to an acceleration in rotation. The shortest day recorded was on July 5 last year, with a 1.66-millisecond deviation. Scientists are proposing a negative leap second, a first in timekeeping, prompting concerns about adjustments to clocks and computational infrastructure.
New estimates suggest that the first Tuesday of August will be around 1.25 milliseconds shorter than it should be due to variations in Earth's rotation.
The shortest day ever recorded was on July 5 last year, measuring 1.66 milliseconds shorter, indicating a recent acceleration in Earth's rotation.
Scientists propose a negative leap second to compensate for lost time, meaning world clocks will need adjustments, as this is unprecedented.
Patrizia Tavella noted that a negative leap second has never been added or tested, raising concerns about potential risks.
