Given that 1.59 milliseconds actually takes just a blink of the eye to pass, it's not surprising that average folk didn't notice that one recent day was shorter – by that much – than usual.
But scientists who watch those numbers closely sure did.
A report at Phys.org confirmed scientists at the National Physical Laboratory in England recorded the shortest day ever on June 29 and another shortened day on July 26.
Citing documentation from Popular Mechanics, the report said, "On both of these days, the Earth completed its usual 24-hour rotation in less than 24 hours … June 29 was 1.59 milliseconds shorter than usual—the shortest day since the 1960s when scientists began using atomic clocks to measure time."
On July 26, the day was nearly 1.5 milliseconds shorter than usual.
