April 1, 2001

This Sunday (1 April 2000) is a planned end of 3-month time measurement check. On this day we plan to check our reference timepieces with Atomic Time, keeping track of any current discrepancy. Our clocks are set ahead one hour on this date. Daylight savings time begins in the US. The purpose of this team project is to determine the long-term accuracy of our LCD digital timepieces and to ultimately measure the slowing of the earth's rotation as the 12th approaches. For those who wish to participate, send your readings to me, so I can update our spreadsheet.


Here's the data (using Socketwatch):
