It is not productive to run ntpd on a virtual machine. Run it on the
real machine underneath and get the time from there. Virtual machines
have highly inconsistant system clocks. 

And ntpd does reseat the time if it is off by 128ms Of course you
probably have to wait 8 cycles so it can be sure that it is the time
that is off and not the roundtrip.
