Hi, I have installed Debian under client Hyper-V in Windows 8.1 Pro and the time is not synced after a resume, the clock just goes one like nothing happened. So if the guest VM was in a saved state for one hour, its clock would be late one hour after resuming the VM. The source of 'hv_utils' suggests the guest's clock schould be synced after such a resume event. How can I find out what is happening? I can code C a little bit. Thanks, Sladjan
