Each day the OS is off. If i reboot it corrects but by the next day the time has fallen behind. I rebooted it two days ago and right now it is 2/18/2020 at 12:33pm but the OS has 2/17/2020 12:27pm? Any idea why this is happening. Thank you Gary February 19, 2020 at 3:15 pm #64387 RayKeymaster Did you check if the ‘Location’ you set is correct? The controller uses your location to obtain time zone automatically, so if the location is incorrect that will result in the time being different.

I have left both units running for 3 days so far and the date and times are remaining correct. If anyone else has this problem, the battery in the OS i have was difficult to see, i had to remove the display which is attached with pins into a socket on the mother board, It wiggles out easily.
