That graph makes it look like 5 seconds shorter is no problem? How could a millisecond be a record?
I believe you’re looking at the wrong y axis.
You are correct.
Not shorter than 5th of July 2024 though, where the delta apparently was -1.66ms, and thus still the record since measuring.
The graph that bleistift2 posted also supports this. At least it’s visible that the lowest point was somewhere in the middle of 2024, and that it was a bit under -1.6ms.
‘Approximately 1,34 ms’. :D
I’m guessing by “history” they mean since we started measuring this accurately? Iirc the earth used to spin faster so going back a few centuries or millennia should give days measurably shorter than what we have now.
Yes, shortest since measuring with an atomic clock, in 1973.
