Summary of NTP from RFC-1305 Network Time Protocol (Version 3):
NTP is used to synchronize timekeeping among a set of distributed time servers and clients … It provides the protocol mechanisms to synchronize time in principle to precisions in the order of nanoseconds while preserving a non-ambiguous date well into the next century.
The Network Time Protocol (NTP) client is essential for syncing time on various clients in the system. This document shows how to view NTP status and configure NTP on a Dell switch.
