Cool sites: Time

As you might know from my success at the Geek Quiz, I am a geek, and one characteristic of being a geek is that your watch/computer/VCR clocks are all set to the highest accuracy possible. I use the Official U.S. Time to set all my clocks (I just checked my watch and computer against the site, I'm within 15 seconds on my watch and within 1 second on my computer.)

The site is maintained by NIST (National Institute of Standards and Technology) and the USNO (U. S. Naval Observatory). Readings from the clocks of these agencies help determine UTC (Coordinated Universal Time) used by the GPS. The time maintained by both agencies never differs by more than 0.000 0001 seconds from UTC

Some other cool sites about time include this list of sites on the time.gov site, the NIST FAQ, a map of world time zones, official Greenwich Mean Time, and How Time Works on the excellent How Stuff Works site. Wikipedia has a good list of references as well on its Time page.
