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.
For further details see the clockkit repository.
Currently this crate does package a server (amd64) for testing purposes, but the provided API is for the client side only.
At the moment this crate is nightly only due to the need for atomic_mut_ptr to
interact with the wrapped code.
t_server_manual: Do not attempt to start the included server for the test,
but expect it to be started manually before tests run.
