 From Science Alert:

Led by a team from the University of Southern California (USC), the researchers behind the finding think this change in the core's rotation could change the length of our days – albeit only by a few fractions of a second, so you won't need to reset your watches just yet.

"When I first saw the seismograms that hinted at this change, I was stumped," says Earth scientist John Vidale from USC.
