> WWVB clocks running off the 60KHz pretty much solve the clock problem in the US.

YMMV depending upon location. I've never gotten a WWVB clock to work in North Carolina. On the East Coast, the signal maybe sorta works for a few hours overnight:

Edit: My bad, they can switch in/out of DST automatically, at least when they can work at all.

I have a few WWVB clocks. The ones that are on the north/south walls will never sync on their own, but east/west walls will sync just fine. I just take down the north/south clocks twice a year and lean them on a west facing wall and they'll sync overnight.

I think that most WWVB clocks just don't have the size to have an omni-directional antenna.

If I have to take the clock off the wall and move it outside, I may as well set it by hand. In any case, I've tried leaving one outside facing west and it still doesn't work. I've literally never had one of these clocks work from NC.

Meanwhile, the WiFi NTP clock I purchased just works, like I always hoped the WWVB clocks would have.

I'm fairly certain the radio time signal has a mechanism to convey daylight savings, I've had alarm clocks that managed DST without any input.

You're right. I was wrong about that, mostly because I've never had a WWVB clock work for me at all.
