The time values are in milliseconds, not seconds.

Yes, that's right, my bad. :(
But that's not the point, really.

The offets keep increasing and increasing up to the point
where ntpd.exe drops all the servers and sync_ntp flag is lost.

The exact same ntp servers are used on Linux VMs running on the same
QEMU/KVM host and they do not show the increasing offsets and jitter
values.

Something is awry and i can't figure out what, where and why. :/

Windows isn't a very good timekeeper anyway.

I don't find it surprising that Linux VMs are behaving nicer. Linux timekeeping is more stable anyway, and since QEMU/KVM is also based on Linux I would expect they work better together than Windows on Linux.

I see you already run ntpd v4.2.8 in your VM, which already contains a workaround for another deficiency in Windows, where small tick adjustments are not handled correctly.
