    Abstract: A method of performing clock synchronisation across multiple devices, the method including: in a first device: emitting timing pulses based on a first clock signal; and, outputting event data including events associated with first event times based on the first clock signal; in a second device: receiving the timing pulses; and, generating reference data including an indication of each timing pulse associated with a reference time based on a second clock signal; and, in one or more processing devices: receiving the event data; recording an approximate local event time for each event based on a time of local receipt determined using a local clock signal; using the local event times and first event times to derive a first function that relates the first clock signal and the local clock signal; using the first function and the reference data to derive a synchronisation function relating the first and second clock signals; and, using the synchronisation function to perform clock synchronisation of the first and second clock signals.
