I tried atomic clocks but they wouldn't work unless they were on the southwest corner of the house. It even said in the manual that if it's not working, to try putting it there. Kind of defeats the purpose setting itself if I have to move it to a specific corner of my house twice a year.

Though I didn't want a digital clock--my goal was an analog-style clock that never needed any maintenance. And it ends up there are some reasonably priced ones on Amazon that just connect to WiFi once a day and adjust if necessary, including to account for DST. I have it set to run at 4am each day, so any DST adjustment happens while I'm still sleeping.

The only final step is to run hardwired power to it so I don't need to change batteries, but I haven't pulled that trigger yet. Often with projects like this, it's more fun to prove out the difficult parts and I lose interest once only the easy parts remain.
