Products that don’t have Real-Time Clock chips have no way to keep the time 
of day when they are powered-off. With SNTP they can keep the time of day 
synchronized with an appropriate network time server, which makes it 
possible to analyze some events (such as link failure) more accurately. The 
following command lines configure SNTP for the installation location (Time 
Zone) of the SIA2410R, identifies the NTP Public Time Server (by it’s IP 
Address) to use and sets the polling interval (in seconds) desired. 
 
SIA2410R(conf)# sntp unicast 131.107.1.10 3600 
SIA2410R(conf)# sntp utc -8 
 
The first line is the IP address of the NTP time server and the polling interval. 

You can find the appropriate public NTP time server at 

www.ntp.org

. The 

Polling interval, in seconds, determines how frequently a time inquiry should 
be sent to the NTP time server. The 3600 indicates that the time of day should 
be updated every one hour. The UTC (Universal Time Coordinate) in the 
second line shows the time difference from GMT (Greenwich Mean Time) time. 
If you are in San Francisco, for example, the local time is 8 hours earlier than 
GMT, so you should set it to “ -8”.
