[Users] Timezone Hypervisor/VM

[Bob Doolittle]

I'll be happy to try a patch, if you can deliver it in a convenient way 
for me to install.

The bug comments and synopsis are misleading so at first I didn't think 
this was it. The bug specifically says "Time is off by exactly 1 or 3 
hours, depending on VM" and the synopsis says "time is off by as much as 
3 hrs".

My time is currently 4 hours off (I think it was 5 before Daylight 
Savings Time).

The release note text states the issue correctly though, I think.

The only thing giving me any doubt is that all my non-Windows VMs are 
fine. The problem is isolated to Windows guests.
