Has anybody measured that?
Is there a good URL on this? (predictions if not data) All I've found so
far is a small NASA press release predicting 1.26 microseconds per day:
http://www.nasa.gov/topics/earth/features/earth-20100301.html
(and a zillion news sources repeating it)
1 microsecond/day is 1 part in 1E11.
