Really? I would've thought NIST would be the official
clock. But, I went to www.usno.navy.mil and it plainly
states: 
"The U.S. Naval Observatory performs an essential
scientific role for the Navy, for the Department of Defense
and for the United States. Its mission is to determine the
positions and motions of celestial objects, to provide
astronomical data, to measure the Earth's rotation and to
maintain the Master Clock for the United States."

I thought the US Atomic clock was in Boulder... How's it
get to DC from Boulder?
