Earth is spinning faster this summer, making the days marginally shorter and attracting the attention of scientists and astronomers. Some days have clocked in at slightly less than the standard 24 hours, and timekeepers are considering an unprecedented move .

Scientists predicted that Tuesday will be a fraction of a second shorter than normal as the Earth's rotation is moving faster.

A tiny shift in Earth’s spin could trigger a move timekeepers have never made before, and it might impact everything from satellites to global networks.
