While diving deep into DCF77, I noticed there is something similar for the US:

It just doesn't seem to get used that much, I suppose?

The shortwave WWV, not so much, except to check if your shortwave radio is working. Canada's shortwave CHU was shut down last month.

The 60 kHz WWVB, yes. Plenty of cheap wall clocks have "atomic time" as it is marketed over here, meaning it has a radio receiver. You can pick one up at the grocery store. It depends on where you live if it actually works though. Where I live it works pretty well, but I've heard it does not work so well if you live on the east coast. That's quite a ways from Colorado.

I think both WWV and WWVB were on the chopping block a few years ago, because the government decided it wasn't worth the $100,000 per year to keep them running. Thankfully that decision was overturned.

It's less common now, but you used to see them frequently. Most people didn't really know how they worked though, and had never heard of WWV or WWVB.
