It no longer works via qemu, that portion is disconnected.
You can currently set a new time offset for an HVM domain, but there is
no current mechanism to read the time offset or get notification if an
HVM guest changes it.
I submitted a patch a week or so back to implement these, but the status of that is uncertain (at least to me).
I guess I should revisit the status of the patch.

When the rtc for hvms was moved from qemu to hvm was the whole operation moved over?
What I am getting at is that the initial time should probably still be set in qemu
and hvm rtc should respect it. That way the -localtime option would still work as
advertised and there would be no need to have ported gmtime() over.
Also any adjustments done to the rtc in the hvm during run-time should be at the
second and millisecond level as guests might have their clocks set to other times
or timezones, either because they are running Windows, or are being set forward or
backwards for testing purposes.
