3.3 Time The system date and time of the router can be configured via this option. The system date
and time can be configured manually, or it can be obtained automatically from a global
time server using NTP.
NTP is designed to synchronize the time on a network of machines. NTP runs over the
User Datagram Protocol (UDP), using port 123 as both the source and destination port.
NTP Version 3 RFC 1305 is used to synchronize timekeeping among a set of distributed
time servers and clients.
An NTP network usually gets its time from an authoritative time source, s uch as a radio
clock or an atomic clock attached to a time server. NTP Protocol is then used to distribute
this time across the network. An NTP client makes a transaction with its server over its
polling interval (from 64 to 1024 seconds) which dynamically changes over time
depending on the network conditions between the NTP server and the client.
The list of public NTP servers is available at http://www.ntp.org.
