Earth Core Rotating Faster
If as they say the Earth's core is rotating faster than
the outer portions wouldn't it transmit causing the day to get shorter?

The day is really getting longer due to the effects of tidal friction slowing the rotation down. But don't expect to notice it very much.

Interesting, but at only 0.3 to 0.5 degrees per year, it's a very small, but yet significant, difference. Besides, it says the outer core seems to act as a buffer, decoupling its motion from the mantle. But it's interesting nevertheless.
