we have some question
  1. NTP time synchronize time per 1 hour,How
     do we define sync every 10 minute?
  2. NTP Message error:0.005623 is correct,
     If is not correct,could you explain
     the message.
could you send mail this answer to my mail.
thanks/best regards.
 


The Answer is :

 
  This NTP configuration looks to be operating normally.
 
  For information on configuring and operating NTP, please see the
  TCP/IP Services Management documentation.
 
  For control over the polling interval, please see the documentation
  of the ntpq and ntpdc commands.
 
  You will want to verify that your NTP time-base -- and preferably an
  NTP server time-base, and not an SNTP server time-base -- is stable,
  and is not encountering some form of jitter.
 
  If you are seeing a particular problem, please apply the available
  ECO kit for TCP/IP Services and please contact the support center
  directly.
