@Moon the only one I’ve ever had was a 0w that I tried to set up a pihole/unbound server on. That didn’t last long, brief power outages aren’t that uncommon here and the lack of anything to save the state of the system clock would kill DNS for me since every ssl handshake would suddenly fail if the power had so much as a hiccup. Trying to figure out how to sync ntp out of band was a headache, so I would set the time manually but eventually I decided it was more trouble than it was worth.
