The signal sounds just like a banger DJ intro.

[MAN] at the tone. 22 hours. 8 minutes. coordinated universal time.

[WOMAN] follows is a scientific modulation test. for more information visit DJ NIST

Yeah, I got Aphex Twin vibes from it: https://www.youtube.com/watch?v=ip2w2mNFTAc

You’re in for a treat - https://youtu.be/qN8tm5RulFU

That signal almost sounds like you could make a clock from it. Like you manually set it and it syncs to beat in the video.

That's the whole point: https://en.wikipedia.org/wiki/WWV_(radio_station)#Broadcast_...

The "clicks" are second markers, and the low-frequency hum that follows each click encodes a single bit of a binary datastream conveying the current time. If you've ever had an automatic clock in the US, it sets the time by tuning in to WWV and decoding this signal.

I think most automatic clocks are setting themselves based on WWVB, not WWV.

It broadcasts on longwave rather than shortwave and uses a different modulation.

You don't even need to manually set it, the date and time is encoded in the tones.
