Earth has recorded its shortest day on record, with concerns a 'leap second' could be needed to keep clocks correct.
Last month almost 1.6 mili-seconds were shaved off one particular day, raising questions about a 'negative' moment to re-align time.
According to Forbes, we could be beginning a 50 year period of shorter days.
Timekeepers have been forced to add 27 'leap seconds' since the 1970s, which involves creating a minute with 61 seconds to keep clocks correct.

Astronomical Institute researchers say 1.6 mili-seconds might not be noticable in isolation, but it can add up and throw clocks off the sunrise-sunset schedule.
It's thought that the melting of glaciers and seismic activity could be among causes for the shift.
