The will no longer work on current, where ntpd will only bump the clock
if securelevel is 0 and the -s flag no longer exists.
You could use rdate, though it is not secure (it will accept any
network input) and in general it is unwise to bump the clock on a
running system. This should be solved in vmd some day I suppose,
assuming the vm *can* determine it is being unsuspended by the host.
It might be better to zzz the vm before telling the host to suspend
it. When resuming the vm kernel will do the right thing.
