The earth's solid core is supposed to be spinning a bit faster than the crust/mantle daily 2/3 second x 365 days in a year means the inner core is gaining on the outer part of the planet about 4 minutes!

"The inner core rotates in the same direction as the Earth and slightly faster, completing its once-a-day rotation about two-thirds of a second faster than the entire Earth. Over the past 100 years that extra speed has gained the core a quarter-turn on the planet as a whole, the scientists found. Such motion is remarkably fast for geological movements -- some 100,000 times faster than the drift of continents, they noted. The scientists made their finding by measuring changes in the speed of earthquake-generated seismic waves that pass through the inner core. "
