Function Keys - La Crosse Technology WS-9520U Instruction Manual

The WWVB radio station receives the time data from the NIST Atomic clock in Boulder, Colorado. A team of
atomic physicists is continually measuring every second, of every day, to an accuracy of ten billionths of a
second per day. These physicists have created an international standard, measuring a second as
9,192,631,770 vibrations of a Cesium-133 atom in a vacuum. For more detail, visit
http://www.boulder.nist.gov/timefreq.htm. To listen to the NIST time, call (303)499-7111. This number will
connect you to an automated time, announced at the top of the minute in "Coordinated Universal Time",
which is also known as Greenwich Mean Time (GMT). This time does not follow Daylight Saving Time
changes. After the top of the minute, a tone will sound for every second. It is possible that your weather
projection station may not be exactly on the second due to the variance in the quartz. However, the clock will
adjust the quartz timing over the course of several days to be very accurate; under 0.10 seconds per day.
