Time change

We got daylight savings time here in the US yesterday, but that is not the only time that has changed during last week.  During the horrific earthquake in Japan, which led to the equally horrific tsunami, this also happened:

"NASA scientists calculated that the redistribution of mass by the earthquake might have shortened the day by a couple of millionths of a second and tilted the Earth’s axis slightly." (link to NY Times story)

Nature is powerful, indeed.
