You may have arrived at this view due to lack of visibility on what WWV does. WWV also provides: - stable reference frequencies for maritime and aviation radio and also for terrestrial radio tuning - space weather alerting for radio system operators - GPS system status updates for maritime and aviation - High accuracy intervals and UT1 corrections (which used in conjunction with GPS for highly accurate position measurements) Despite sounding like some legacy thing, this is a highly active system used by a lot of folks. I built a stratum 1 NTP system for power grid a few years ago using EndRun high accuracy appliances and we used GPS and WWV as the sources. https://tf.nist.gov/stations/iform.html https://tf.nist.gov/stations/iform.html

The reference frequency part is very important. There is a lot of test gear that relies on a 10 MHz signal for calibration.

  Very accurate reference frequencies can be obtained by syncing an oscillator to a GPS receiver clock output (0). I'm however all for maintaining traditional shortwave (not just time and frequency) radio stations on, for being much easier to receive and harder to control by governments. 0: https://en.wikipedia.org/wiki/GPS_disciplined_oscillator https://en.wikipedia.org/wiki/GPS_disciplined_oscillator
