	Not true.  128msec is the threshold for stepping versus slewing. 
Being 200 seconds out before starting ntpd is not a problem.  Being 
more than 1000 seconds out before starting ntpd could be a problem, 
if you don't use the "-g" option.

	You didn't read a word he wrote, did you?  He said that he 
doesn't have a version of ntpdate that has been ported over, so he 
used "ntpd -q" instead.

	Which is exactly what he did.  Go back and re-read what he wrote, 
but this time pay attention.
