NTP Project

In the early 1980s the Internet was very young, and it didn’t have many services running on it. David L. Mills, Ph.D. decided to tackle the problem of distributing “time” on the Internet. By the spring of 1981 he had written the software and specification for the first clock service on the Internet, and by… Read More.

Ntimed Project

Ntimed is a tightly-focused NTP implementation designed for high security and high performance. The NTP Project’s software is most likely the longest-running software project on the Internet. It was designed as a Reference Implementation, so it does as much as it can to make sure that the complete NTP Protocol specification can be demonstrably proven… Read More.

Linux PTP Project

The Linux PTP Project is a Linux-focused software implementation of the Precision Time Protocol (PTP) specification that meets or exceeds the IEEE 1588 Standard. Its dual design goals are to provide the highest possible performance levels and be a thoroughly robust implementation of the PTP Standard. Linux PTP uses the most relevant and modern Application… Read More.


The RADclock project (formerly known under the name ‘TSCclock’) aims to provide a new method for network timing. We are developing alternatives to NTP clients and servers based on new principles, in particular the need to distinguish between difference clocks and absolute clocks. The term RADclock, ‘Robust Absolute and Difference Clock’, stems from this. The… Read More.

General Timestamp API Project

NTF’s General Timestamp API Consortium exists to foster the development and implementation of a new “general timestamp” structure, and a portable and efficient API library built around this new structure. Why? The information contained in a current timestamp is usually a date and time, sometimes with fractional seconds. This has usually worked because the folks… Read More.

Collaborative Projects

Sometimes it takes a village to successfully create a project and bring it to fruition. While the projects listed below receive minimal support from and are not directly owned by the Network Time Foundation, we do help each other out for the betterment of all involved. Without joint efforts such as these, Network Time would… Read More.
