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 Wireless Weather 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
.
