EtherTime is an open-source benchmarking tool developed to evaluate the performance of various time synchronization protocols on Ethernet-based distributed systems. This tool is designed to assess the strengths and weaknesses of the supported implementations in different configurations, focusing on dependability and fault tolerance, with integrated support for PTPd, LinuxPTP, Chrony and SPTP and offering easy extensibility for new time synchronization applications. It was described in the following publication:
