The NTP pool is a dynamic collection of networked computers that volunteer to provide highly accurate time via the Network Time Protocol to clients worldwide. The machines that are "in the pool" are part of the pool.ntp.org domain as well as of several subdomains divided by geographical zone and are distributed to NTP clients via round-robin DNS .
The Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. In operation since before 1985, NTP is one of the oldest Internet protocols in current use. NTP was designed by David L. Mills of the University of Delaware.

An existing network server (e.g. a file server) can become a time server with additional software. The NTP homepage provides a free and widely used reference implementation of the NTP server and client for many popular operating systems. The other choice is a dedicated time server device.
Subsequent investigation revealed that four models of Netgear routers were the source of the problem. It was found that the SNTP (Simple NTP) client in the routers has two serious flaws. First, it relies on a single NTP server (at the University of Wisconsin–Madison) whose IP address was hard-coded in the firmware.
ntpdate is a computer program used to quickly synchronize and set computers' date and time by querying a Network Time Protocol (NTP) server. It is available for a wide variety of unix-like operating systems.

Many Unix-like operating systems used the Time Protocol to monitor or synchronize their clocks using the rdate utility, but this function was superseded by the Network Time Protocol (NTP) and the corresponding ntpdate utility. NTP is more sophisticated in various ways, among them that its resolution is finer than one second.
