OpenNTPD 4.6 released Nov 1, 2009.
Portable OpenNTPD 3.9p1 released May 14, 2006.

OpenNTPD is a FREE, easy to use implementation of the Network Time Protocol. It provides the ability to sync the local clock to remote NTP servers and can act as NTP server itself, redistributing the local clock.

OpenNTPD is primarily developed by Henning Brauer as part of the OpenBSD Project. The portable version is made by Darren Tucker. The software is freely usable and re-usable by everyone under a BSD license.

Managing the distribution of OpenNTPD is split into two teams. One team does strictly OpenBSD-based development, aiming to produce code that is as clean, simple, and secure as possible. We believe that simplicity without the portability "goop" allows for better code quality control and easier review. The other team then takes the clean version and makes it portable, by adding the portability "goop" so that it will run on many operating systems (these are known as the p releases, and named like "OpenNTPD 3.9p1").

The OpenBSD project sells CDs, T-Shirts and Posters. Sales of these items help to fund development.
