About Time
By Science News
To find out the official time, visit the joint Web site of the National Institute of
Standards and Technology and the U.S. Naval Observatory. Two
ultraprecise clocks contribute to a pool used to define “coordinated universal
time.” These two clocks are not supposed to differ by more than one
ten-millionth of a second. The site also provides links to presentations on
topics such as timekeeping, calendars, and clocks.
