<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hello,<br>
<br>
you are right. Only Windows VMs show that behaviour. But for Linux the <br>
problem is even more strange: Have a look at my database for a specific<br>
Linux VM:<br>
<br>
engine=# select a.vm_name,b.utc_diff from vm_static a, vm_dynamic b where a.vm_guid=b.vm_guid;<br>
vm_name | utc_diff<br>
------------------+----------<br>
colvm53 | -271973<br>
<br>
Logging into the VM it shows the correct time but the hardware clock is far away according to utc_diff:<br>
<br>
colvm53:~ # hwclock<br>
Tue Feb 4 12:49:21 2014 -0.173138 seconds<br>
colvm53:~ # date<br>
Fri Feb 7 16:20:42 CET 2014<br>
<br>
Maybe because it reads the KVM/QEMU timing values another way than Windows.<br>

<p dir="ltr">Marcus, </p>
<p dir="ltr">Are all your VMs Windows? Because I have a mix and only Windows VMs are affected. Seems like changing utc_diff should only be done for Windows VMs (Linux happy to work with a hardware clock of GMT).</p>

Hi Dan,<br>
<br>
just saw the bug update with target 3.4.1. Could you<br>
reproduce the bug and do you have some advice how to<br>
handle that setting until then? And what should I expect<br>
when daylight saving takes place in march?<br>
<br>
>From my understanding I would:<br>
<br>
- pin all VMs to utc_diff=3600 (GMT+1) now<br>
- pin all VMs to utc_diff=7200 (GMT+2) after change of summertime<br>
<br>
