I tried to adjust the time on my alarm clock

Better is just use GPS. You can passively listen without being tracked and you get the time and location. GPS is getting cheap enough ($10/1000 qty) to be a good option for this sort of thing.

Doesn’t work super well when your clock needs an unobstructed view of the sky. How many clocks in your house have that?

It's not like it needs a solid fix though. It just needs a single satellite signal to get through, which is way more reasonable.

I have a higher end GPS module. Building I'm in is corrugated steel sided with a metal roof. After being on for an hour the coordinates show... my desk. Far as I can tell.

GPS transmit power is 44db with a 13 db antenna gain. I think. And -140 db sensitivity (typical) So close to 200db of link margin. And the transmitter isn't in clutter either.
