The Open Traceable Time Platform is an open-source solution for a timing system that can be made fully traceable to national standards. It achieves traceability using the GPS common-view technique, which allows distant clocks to be compared with an accuracy of a few ns. The reference platform is based on readily available, low-cost OEM modules and provides a full software and hardware solution. More information can be found on the project website www.openttp.org

Documentation can be built from the LaTeX source in the doc/manual directory by running 'make'. The documentation contains instructions for a minimal installation. A PDF of the documentation is also available from www.openttp.org/scripts/docs.php
