Daylight Saving Time (DST) On/OffGLOSSARY OF COMMON TERMSLCD“LCD” is an acronym for ”Liquid Crystal Display”. This is a common type of display screen used intelevisions, computers, watches, and digital clocks.LED“LED” is an acronym for “Light-Emitting Diode”. This type of light is used to illuminate a variety ofdisplays such as a digital clock or watch.NISTThe National Institute of Standards and Technology (Time and Frequency division) maintains theprimary frequency standard for the United States. The NIST also coordinates the United States timeand frequency standards with other world standards. The NIST provides time and frequency servicesfor United States clientele.WWVBThe WWVB is an AM radio station in Ft. Collins, Colorado, managed by the NIST. The WWVB’sfunction is to broadcast time-of-day information derived from the NIST atomic clock, located inBoulder, Colorado.ATOMIC CLOCKAn atomic clock is an extremely accurate time device measuring time by the movements of electronsin cesium atoms. The NIST atomic clock is one of the most precise clocks in the world, accurate to10 billionths of one second. The NIST’s atomic clock contributes to the international group of clockscalculating the Coordinated Universal Time (UTC)—the official world time.RADIO CONTROLLED TIMEA radio controlled time device is often confused with an atomic clock. However, a radio controlledtime device receives its time information from the atomic clock each day through an internal antenna.The radio controlled time device searches for an exact time signal every night when the signal fromthe WWVB is the strongest. The signal can be received up to 2,000 miles away through a radiocontrolled time device.For more information regarding the NIST, WWVB, atomic clock, and radio controlled time, please visitthe NIST official website: http://www.boulder.nist.gov/timefreq/stations/wwvb.htm
