Clock not moving in virtual machine

Hi,
I have a VPS from rootbsd.net which is running current, though I don't
update it very often. I just built and installed a new world and
kernel and now the clock will not move from the time the system was
booted, ie:
# date
Thu Jul 15 16:15:58 PDT 2010
<wait a minute>
# date
Thu Jul 15 16:15:58 PDT 2010
I have an old kernel from May 27 which doesn't have this problem. I
noticed some clock related stuff changing in current in the last
couple of weeks and suspect that their VM setup doesn't play well with
these changes (their site says they use Xen, but several boot messages
refer to QEMU). Officially, I think they only support running 8.0 so I
thought I would ask here if anyone has any ideas before putting in a
support request.
Here's a diff of the dmesgs - I can post full copies if needed but
didn't want to start with a ridicously long message:
