let the host sync the system clock and hope that it doesn't run off

Can you freeze and continue any other non-VM system?  Is it comparable
with suspend/resume?  If not, than it is a special case that could be
handled without being scared about a "VM-specific" option.  For
example: The timedelta sensor could tell userland that it "might
jump".  ntpd would pick it up from vmt automatically.

I think that adding another button is worse.  It is already annoying
to decide if I want to run ntpd with -s or not.  Now it would add -j
and -s.  What combination is the best for my system?  Who knows?
