The pole shifted all of three inches and the day got shorter by 1.26 microseconds. So if your feeling a bit lost and short of sleep you have an excuse.

NPR had a bit on it this morning that noted that neither the three inches nor the shorter day have been observationally verified. Those values are theoretical and are apparently too small, in relation to normal variation, to be show up.
