It's as if the clock is a few milliseconds faster than real time, so at first you don't notice, but then eventually over a few days, it's 3...then 5....then 10 seconds ahead. After a few months it's a good minute or two ahead of all my other clocks. I did a factory reset a few days ago to see if that would fix the problem, but already the clock is ahead of real time by about 5 seconds and there's no option on these tablets for automatic time set. I've seen this issue come up on the Tab Pro forum, but nobody was able to provide a solution. Does anyone know how to fix this? It's a small quirk, to be sure, but an issue like this drives my OCD insane.
