I suppose you are seeing=0A=

I implemented the above patch on one of our hypervisor nodes. But this=0A=
does not change anything. The VM has always the time difference after reboo=
t=0A=
that is set in table vm_dynamic.=0A=
=0A=
We are on GMT+1. if utc_diff =3D 0 Windows VM time is on hour back. If=0A=
utc_diff =3D 3600 Windows VM time matches.=0A=
=0A=
Should I file a new BZ?=0A=
