Configuring SNTP Setting the clock based on an SNTP server can provide more accurate clock
synchronization across network switches than manually-configured time. To
configure SNTP, set the switch as an SNTP client, and then set the polling interval,
and specify a time server as shown in the following example.
Console(config)#sntp client
Console(config)#sntp poll 60
Console(config)#sntp server 10.1.0.19
Console(config)#exit
Console#show sntp
Current Time : Apr 2 16:06:07 2013
