from what I was finding it looks like the ntp-sync is used in the from 
crontab.  What do you get if you crontab -l ?  I found reference to where 
that is either ntp-sync or just set to pools.NTP.org just like you would do 
it manually.  M
y issue with the crontab way was if it ran before network was up it would 
be 30 mins before it set the date/time.
