Chapter 19 NTP function configuration

19.1 Introduction of NTP function

The NTP (network time protocol) synchronizes timekeeping spans WAN and LAN
among distributed time servers and clients, it can get millisecond precision. The
introduction of event, state, transmit function and action are defined in RFC 1305.
The purpose of using NTP is to keep consistent timekeeping among all
clock-dependent devices within the network so that the devices can provide diverse
applications based on the consistent time.
For a local system running NTP, its time can be synchronized by other reference
sources and can be used as a reference source to synchronize other clocks, also can
synchronize each other by transmit NTP packets.
