Description of problem:

Windows 10 Pro and Windows Server 2012 R2 were tested with the latest RHEV Tools installed, and in RHV-M have the ! indicating that Timezone in guest differs from configuration error. This is only noticed with PST (GMT -8) as the Timezone.

Version-Release number of selected component (if applicable):

RHV 4.1.9, RHEV Tools 4.1-7, Windows 10 Pro, Windows Server 2012 R2

How reproducible: 100%

Steps to Reproduce:
1. Install Windows VM, set hardware offset to GMT -8 
2. Set Windows VM to PST -8
3. Observe ! in RHV-M

Actual results:
! in RHV-M to the left of the VM indicating "Actual Timezone in Guest Differs from Configuration Error".

Expected results:
There should not be any reported time differences.


Additional info: 

engine=> select utc_diff,guest_timezone_offset from vm_dynamic where vm_guid = (select vm_guid from vm_static where vm_name ='win10-test');

 utc_diff | guest_timezone_offset 
----------+-----------------------
   -28800 |                  -480

This appears to be correct. Also there are several time zones for -8 in Windows 10, all of them report this error.
