  author={Reinhard Exel and Georg Gaderer and Nikolaus Ker{\"o}},
Clock synchronization is a service widely used in distributed networks to coordinate data acquisition and actions. As the requirement to achieve tighter synchronization accuracy arose, protocols like the Precision Time Protocol introduced hardware timestamping, shifting the point where the timestamp is drawn from the application layer twards the physical layer. However, the spread of the synchronization service between hardand software increased the complexity of the system and still could not… CONTINUE READING
