The National Institute of Standards and Technology (NIST) operates radio station WWVB, which broadcasts the official time of the United States. The broadcast has emanated from Ft. Collins, Colorado, since 1963, and transmits the year, day, hour, minute, second, other time information, and various indications, using a one-minute-long data frame on a carrier frequency of 60 kHz. Similar broadcasts are in use in other parts of the world, such as in Japan, Germany, and the United Kingdom. See also: Carrier (communications); Radio broadcasting
