manufacturer: description:coordinated universal time (utc) is a stable reference frequency used for counting seconds. the frequency, or rate, of utc is computed by the international bureau of weights and measures (bipm), based near paris, france. the bipm uses a weighted average from about 250 atomic clocks located in about 50 national laboratories to construct a time scale called international atomic time (tai). once tai is corrected for leap seconds, it becomes utc, or the official world time scale. nist distributes a real-time version of utc called utc(nist), a time scale referenced to atomic oscillators located in boulder, colorado, to the public through their time and frequency services. at its source, utc(nist) is kept in as close agreement as possible with other national and international standards (typically within a few nanoseconds). |
