Time Machine

Happy birthday Atomic Clock! The BBC is reporting that the Atomic Clock is 50 years old this year. The first one was built in 1955 by Dr. Louis Essen. Current versions of the clock will lose less than a second in 30 million years. Huh.

For those in the U.S. the official time is provided by the Time and Frequency Division of the National Institute of Standards and Technology, an agency within the U.S. Commerce Department's Technology Administration. (Gotta love the government.) Give 'em a call at (303) 499-7111 and they'll be happy to give you the current time. (Or click here)

It's hard to imagine, but prior to the Atomic Clock time keeping was based on the rotation of the Earth.
