I am trying to narrow down the time drift issue on the 2.3AC running 2.19 firmware. I was waiting for it to happen again on my spare test system, after which i was going to reduce the number of zones to see if it happened again.
Yesterday for some unknown reason the OS rebooted itself. I have it on a backup power supply so there is no reason it should have rebooted.
This morning i attempted to look at it in the browser and could not access it. I looked at the display and it displayed something i had seen one time before and posted originally in this thread. See attached image.
