Is there still an atomic clock signal?

Atomic Time & Date Atomic clocks automatically synchronize to a radio signal called WWVB that the National Institute of Standards and Technology (NIST) broadcasts continuously from Fort Collins, Colorado. This signal transmits the official time from the Atomic Clock in Boulder, Colorado.

What is WWV used for?

The National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards, broadcasts a time and frequency service from stations WWV in Fort Collins, CO and WWVH in Kauai, Hawaii., commonly known to mariners as the “Time Tick”, used as an aid in celestial navigation.

What does WWVB stand for?


Acronym Definition
WWVB NIST longwave (60 Kilohertz) Standard Time Signal (Radio station callsign)

Who is the voice of WWV?

Jane Barbe
In particular, voice announcements on one correspond to silent periods on the other. WWVH uses a female voice (Jane Barbe) to distinguish itself from WWV, which uses a male voice. WWVH time signals can also be accessed by telephone.

Do radio controlled clocks tick?

Most Radio controlled clocks synchronize themselves with a time broadcast signal once a day, at night, although some check themselves every few hours. Generally, that gives them an accuracy of better than plus or minus a half second a day.

What time does the atomic clock send a signal?

Those that decode the signal just once per day usually do it at midnight or in the very early hours of the morning, because the signal is easiest to receive when it is dark at both WWVB and at the site where the clock is located.

Why doesn’t my atomic clock set itself?

If your clock did not change with Daylight Savings Time (DST), make sure the DST switch on the back of the clock is set to ON. If your clock is off by increments of an hour, the Time Zone (TZ) is set incorrectly. Check the Time Zone switch on the back of the clock. If the problem persists, we have a one year warranty.
