4.5.2  NTP Client Related 

 
The NTP Client Related consists of six fields, a Query Interval and five NTP Server Address Pool 

entries.  The Query Interval is a number (in seconds) entered by the user.  The Query Interval will 
be invalid for the first 300 seconds because the NTP client will be sampling the time once every 
second and adjusting the internal clocks in the NTP servers using the internal Proportional Integral 
algorithm.  After the first 300 seconds, the NTP client will begin repeatedly querying the server after 

every query interval. 
 
The NTP Server Address Pool allows the user to enter up to five NTP server addresses.  The 
system will read the five NTP server addresses and any non-zero address.  The system will try to 

connect to each address to get time synchronization.  Then the system will calculate the average 
time for all retrieved times to get a more accurate time reference.
