Hardware Time Stamping (EN)

Hardware Time Stamping

Hardware Time Stamping is a technique for creating timestamps at the hardware level that eliminates software delays in timestamp creation. This technology enables sub-microsecond accuracy in time synchronization and is essential for industrial applications with extreme requirements for time accuracy. Implementation requires special network components with integrated timestamp functionality. By using Hardware Time Stamping, you can significantly improve the accuracy of time synchronization.
