I recently turned on a first gen iPad mini that had been off for maybe a year and its battery had run down. I unlocked it but got repeated prompts to sign into iCloud with an error when I attempted to do so. I finally thought to check the time and it was set to 2017. Apparently if its too far from the current date, automatic time setting does not work. I had to manually set it to the current date/time, wait a minute or two, then I could toggle on automatic time setting. It’s been a while but I seem to recall ntpd behaving the same way on Unix/Linux and having to manually use ntpdate if the system clock is too far off.
