Network Time Protocol version 4 (RFC 5905) is a spectacularly successful network time transfer protocol. It can be found in almost every IP network. Often NTP messages will traverse leased lines or the “public internet”. Therefore, it is especially important that an NTP client can determine that the NTP server is who they say they are, …Most operating systems, such as Windows, MacOS, and Linux have an option to automatically synchronize the system clock periodically by sending queries to an NTP (network time protocol) server. This synchronization process normally starts automatically when the system is bootstrapped and runs in the background.

Beside the standard IPv4 network protocol it also supports IPv6. Alternatively, there's an older version available which can also be used on Windows 2000 or even Windows NT. Note: The current setup program ntp-4.2.8p15a supersedes ntp-4.2.8p15 and ntp-4.2.8p15-v2. It includes preliminary patches for some minor vulnerabilities, see this KB page.Network Time Protocol version 4 (RFC 5905) is a spectacularly successful network time transfer protocol.

About time synchronisation. Network Time Protocol (NTP) is a networking protocol for synchronising time over a network. Basically, a client requests the current time from a server, and uses it to set its own clock. Behind this simple description, there is a lot of complexity. There are three tiers of NTP servers; tier one NTP servers are ... B=120. Client determines the time spend on the network is B-A- (Y-X)=120-100- (160-150)=10 seconds. Client assumes the amount of time it took for the response to get from the server to the client is 10/2=5 seconds. Client adds that time to the "true" time when the server sent the response to estimate that it received the response at "true" time ...Network Time Protocol (NTP) NTP is used to synchronize the time of the computer within a few milliseconds of Coordinated Universal Time (UTC). It can be implemented in various models like client-server and peer-to-peer. The current version of NTP is ntpv4 and uses the User Datagram Protocol (UDP) and port number 123. In a …This document describes the Network Time Protocol (NTP), a protocol for synchronizing a set of network clocks using a set of distributed clients and servers. NTP is built on the User Datagram Protocol (UDP), which provides a connectionless transport mechanism. It is evolved from the Time Protocol and the ICMP Timestamp message and is a suitable …The Network Time Protocols working group is focused on enhancing existing network time synchronization protocols, such as the Network Time Protocol (NTP), and specifying new network-time-related protocols or extensions for purposes that the existing protocols are not well suited to address. NTP was first defined in the IETF in RFC 958 in 1985.
