BTW, after seeing some "spiritual" comments on Facebook inspired by the news, I posted this:
It changes all the time, the variations are small, the real long term trend is actually for the rotation to slow down, we are not now at a historic extreme. The talks about the leap second are due to cumulative deviations over a few decades, which are normal. The reporting is not factually wrong, but it's limited. Check the LOD (length of day) graphs on the Lick Observatory site:

P.S. gravity isn't constant either[2].

- Florin_Andrei 6y agoYeah, that's crackpot stuff (the facts are right - but completely unrelated to the topic at hand). What is it about the Earth's rotation that draws all the crackpot "theorists"?
