Clockkit provides timestamps to distributed networked PCs with guaranteed bounds on latency and jitter, typically under 10 microseconds, as described in the conference paper Synchronous data collection from diverse hardware.
It runs on Linux, Windows, and Raspi, and needs neither extra hardware nor elevated privileges.
It can measure a system's realtime behavior, by providing a common time reference for events recorded by different sensors (audio, video, gamepad, GPS, SMS, MIDI, biometrics), and for triggering outputs (audio, video, LEDs, servos, motion bases). It did this originally for a full-motion driving simulator with eye tracking and a quickly churning set of other sensors and outputs, for over a decade.
