Coordinated Universal Time (UTC): UTC is the international atomic time
scale that serves as the basis of timekeeping for most of the world.
The hours, minutes, and seconds expressed by UTC represent the time of
day at the Prime Meridian (0 deg. longitude) located near Greenwich,
England as reckoned from midnight. UTC is calculated by the Bureau
International des Poids et Measures (BIPM) in Sevres, France. The BIPM
averages data collected from more than 200 atomic time and frequency
standards located at about 50 laboratories worldwide. UTC is the basis
for all civil time with the Earth divided into time zones expressed as
positive or negative differences from UTC. UTC is also referred to as
"Zulu time." See the Standard Time Zones of the World map included with
the Reference Maps.
