Their response was that there is a known issue with time synchronization. Their suggestion was to diasble Hyper-V time sync integration which, as far as I know cannot be disabled. So I thought I would check the offset differences in the virtual host, the domain controllers, and the astaro. The fdifferences were significant! 54 seconds in time difference. So I went ahead and configure the domain controllers and vhost to sync the time with the same servers as the astaro does. So far, about 6 hours without reboots.
