Buried on page 25 of the 2019 budget proposal for the National Institute of Standards and Technology (NIST), under the heading "Fundamental Measurement, Quantum Science, and Measurement Dissemination", there's a short entry that has caused plenty of debate and even a fair deal of anger among those in the amateur radio scene:

NIST will discontinue the dissemination of the U.S. time and frequency via the NIST radio stations in Hawaii and Ft. Collins, CO. These radio stations transmit signals that are used to synchronize consumer electronic products like wall clocks, clock radios, and wristwatches, and may be used in other applications like appliances, cameras, and irrigation controllers.

The NIST stations in Hawaii and Colorado are the home of WWV, WWVH, and WWVB. The oldest of these stations, WWV, has been broadcasting in some form or another since 1920; making it the longest continually operating radio station in the United States. Yet in order to save approximately $6.3 million, these time and frequency standard stations are potentially on the chopping block.

    I can get GPS time, then produce a signal that will keep my several clocks synced that'd be great.

    Wouldn't take much at all to accomplish that; in fact, many GPS receivers are equipped with a precision 10 MHz reference output that can be (and often is) used to stabilize an SDR or other hardware. It would be the work of just a few hours to talk to a smart GPS receiver (these already exist) and synthesize the WWV(B) format, which is hardly complex, then tack it on a frequency-stabilized transmission at low power, which would allow your local devices to synch up. You could even add a nice synthesized voice of your choice. :)
