WWVB continuously broadcasts digital time codes, using very long electromagnetic waves at a frequency of 60 kilohertz, which are automatically received by timekeeping devices in North America (Canada, USA and Mexico), keeping them accurate to a fraction of a second.
WWV and WWVH broadcasts can also be heard by telephone and about 2,000 calls are received daily, according to NIST. (To listen to the broadcasts by phone, dial +1-303-499-7111 for WWV and +1-808-335-4363 for WWVH).
