I'm very well aware that it is a very common way of "acceptance testing" 
ntpd for people who don't understand it.  However, the correct response 
to such a large offset is to ignore it as long as possible, as, in real 
operation, if it doesn't represesnt a fault that needs fixing outside of 
ntpd, it represents a temporary network disturbance and the local clock 
time is still actually valid.
