WWV

WWV is a time signal broadcast by the U.S. National Institute of Standards and Technology (NIST) from Fort Collins, Colorado. It transmits highly accurate, continuous radio signals on several frequencies, providing precise time and frequency information. These signals include the exact current time, which can be used to set clocks, synchronize communication systems, and calibrate instruments. WWV's broadcasts are relied upon by industries, government agencies, and radio enthusiasts to maintain synchronization and ensure accurate timing across various applications.
