Actually official US Time is provided by both in coordination:



>From http://www.time.gov/timezone.cgi?Eastern/d/-5/java :

               This public service is cooperatively provided by the two time agencies 
of United States: a Department
               of Commerce agency, the National Institute of Standards and Technology 
(NIST), and its military
               counterpart, the U. S. Naval Observatory (USNO). Readings from the 
clocks of these agencies
               contribute to world time, called Coordinated Universal Time (UTC). The 
time maintained by both
               agencies should never differ by more than 0.000 0001 seconds from UTC 
(see recent comparisons). 

According to the most recent posted measurements, the two clocks differ
by 24 ns.

| 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."

| get to DC from Boulder?
