Rebooting vm resets time to wrong zone...

[SnakeByte]

QNAP TS-670 Pro
4.2.0 2016/01/19
Virtualization Station: 2.0.3924

I'm having a strange issue with my Centos 7 VM where when it reboots, the time is 8 hours earlier than it should be.

QNAP Host -> System Settings -> General Settings -> Time, has the correct time zone (GMT-08:00) Pacfic Time
and the Current Date and time in that tab correctly shows the correct time and date.

It is also set to syncronize via ntp to us.pool.ntp.org

The VM has a symbolic link if /etc/localtime pointing to /usr/share/timezone/America/Los_Angeles

If I run "date" I see PST as part of the time, however the time is still wrong by 8 hours in the past.

ntpdate us.pool.ntp.org states "no server suitable for synchronization found"

however ntpdate -d us.poo.ntp.org shows that it can communicate with the server -- it's just that the time difference is too great to apparently do anything?

The strange thing is this:

According to this, what the VM thinks is UTC is actually PST.. which shouldn't be the case. My time zone is being applied twice.

As a test, I changed the timezone of the QNAP host to GMT and then restarted my VM -- the VM now shows the correct time.

Is there a way to tell the virtualization station not to adopt the qnap host's timezone, or otherwise fix this? I can't keep the qnap in GMT because it screws up everything that runs on the host, and I cant change the timezone to GMT in the VM because I need accurate time stamps (it's a vm for surveillance).

Did you find the solution to this? I'm having the same problem.

[PGN-1111]

/share/CACHEDEV2_DATA/.qpkg/QKVM/usr/bin/virsh edit VM_UUID
<clock offset='localtime'/> has to be changed to <clock offset='utc'/>
I couldn't figure out a way yet to make this through non-interactive command line like:
sed -i "s/clock offset='localtime'/clock offset='utc'/gI" "${VM_TEMPLATE}"
This doesn't work.

Easier: you just need to set /etc/adjtime in linux vm to "LOCAL" on the third line.
