The Network Time Protocol (NTP) is a computer software package that serves as a time server and has several useful applications. The Network Time Protocol (NTP) is also referred to as an NTP server or NTP clock. David L. Mills of the University of Delaware created the Network Time Protocol to allow computers to synchronize their internal reference clocks with global clocks. The working mechanism assumes that computers measure local time differently than reference clocks. This paper discusses the theoretical foundations and operational issues of the NTP server and clocks, as well as an overview of some of their most important specifications and properties.
The network time protocol (NTP) is a network protocol that allows computer systems to synchronize their clocks over packet-switched, variable-latency data networks. Several organizations have network devices that either use a Public Internet Time Server or an internal clock. NTP servers are well-suited to IPv4/IPv6 networks and provide encryption and authentication for secure communications, which is expected to drive NTP server growth.
NTP uses coordinated universal time (UTC) to synchronize PC clock times with high precision, providing even greater precision on smaller systems - down to a single millisecond in a local network and within several milliseconds over the internet. Instead of relying on the host to perform such calculations, NTP does not represent time zones. Furthermore, NTP servers are used in a variety of industries, including finance and trading, broadcast, IT networks and data centers, healthcare, and telecommunications.
