About
Time-Card is the heart of the Open Time Server Project, an open-source initiative focused on developing a hypothetical reference model, network architectures, and precision time tools for robust time synchronization within data centers. This project aims to distribute, operate, and monitor time synchronization effectively, even in challenging conditions. The core component is a PCIe card, which provides accurate time using GNSS (Global Navigation Satellite System) and ensures continuous accuracy through high-stability oscillators, such as atomic clocks, during GNSS outages. The project offers an open-source alternative to proprietary solutions, providing all necessary source code, BOM, Gerber files, and binaries for self-fabrication or purchase. It also supports various hardware implementations, including FPGA-based solutions, and integrates with open-source software like ptp4l and chronyd.
