A Day on Earth Has Been Shortened
2004: Earthquake in Asia caused the Earth to move by around seven centimeters and chopped an estimated 6.8 microseconds off the length of a day, NASA said.

Odd isn't it? But a few microseconds are not going to affect you. You needn't change the time on your watch or adjust the clocks at home. However, I was just thinking. If every large scale earthquake could possibly shift the Earth's axis by abit, wouldn't a day on Earth shorten terribly in total for all the major earthquakes we've had over the Millenium?
