ntpd doesn't normally use a worker-standby model (it may if you use 
prefer more than once, although that is an abnormal configuration).  It 
is more like load sharing in that it uses the time from all the 
currently valid servers to discipline the clock.  This should be true 
for any other NTP client, but I'm not sure how w32time behaves.
