Difference in time

Post by Kalyori »

I've got a Windows 10 Guest VM (2/4 cores) on a Windows 10 Host (32GB RAM). I have an i5 6600K @ 4.3GHz. Weirdly enough, Task Manager reports CPU at 3.5GHz in the VM.

I've opened a stopwatch on both the Host and Guest and started them (almost simultaneously)... After 30 seconds (Host) the Guest VM is behind by about 5 seconds, but by 2:20 the Guest is ahead by 5 seconds... by 4:15 the Guest is ahead by 15 seconds.... I can even see it speeding up or slowing down on and off... (Guest)

More problematic is the actual clock is behind by 30 seconds (and I'm using software that requires it to be current time)

Can anything be done about this?

Appreciate any help.

Install the Guest Additions in your guest. See ch. 4.2.1 Guest Additions for Windows.
