Homebuilt system 2 months old. Works flawlessly despite this inconvenience. Gadget default clock suddenly disappeared from screen sometime ago and has not returned. In gadgets app default clock is displayed but even if selected will not display on screen. The region is set correctly and the time is set correctly by me, but despite this this it still changes to am or pm or any time it wishes, generally 3 or 4 hours ahead or behind time. It has a mind of its own.
