The NTP (Network Time Protocol) synchronizes timekeeping spans WAN and LAN
among distributed time servers and clients, it can get millisecond precision. The introdu
ction 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-depe
ndent devices within the network so that the devices can provide diverse applications b
ased on the consistent time.
For a local system running NTP, its time can be synchronized by other reference s
ources and can be used as a reference source to synchronize other clocks, also can s
ynchronize each other by transmit NTP packets.
