Welcome to the home of the Network Time Protocol (NTP) Project. Overview & Contact Data

The NTP Project site, often referenced as Project NTP, is the home of the Network Time Protocol, an open standard used to synchronize computer clocks across networks to the common timebase NTP relies on. The site serves as a technical reference for people who deploy, maintain, or study NTP, including network administrators, system engineers, research groups, and developers who depend on accurate timestamps for logging, transactions, scientific data, and distributed systems. It explains how the NTP protocol works, what time sources are available, and how implementations can be configured and evaluated. The project provides documentation, references for the NTP protocol, implementation notes, and support resources for NTP. Readers can find information about NTP versions, server hierarchies, time sources, and the practical considerations involved in measuring network delay, jitter, and clock accuracy. The site also points to reference materials and community resources that help users understand the relationship between computer time, network time, and authoritative time standards. For organizations that rely on synchronized clocks, the NTP reference sections help clarify deployment choices and troubleshooting paths. What makes the NTP Project notable is its long-standing role as a central source for NTP information that users can trust. It supports the broader ecosystem by conducting research and development, documenting the protocol, sharing implementation guidance, and contributing to the continued evolution of time synchronization methods. The site also includes ways for visitors to support NTP and donate to the project's ongoing efforts, reflecting its reliance on community participation and technical contribution. For anyone searching for a reliable NTP reference, the NTP Project offers a focused, protocol-centered resource rather than a general networking portal.
