1. A method comprising:
receiving one or more sampled sets of correlated timestamps including one or more first timestamps referenced to one or more first clock sources and one or more second timestamps referenced to one or more second clock sources, the one or more sampled sets of correlated timestamps generated based at least on the one or more first clock sources being frequency locked to the one or more second clock sources;
computing, using the one or more sampled sets of correlated timestamps, one or more offsets between the one or more first clock sources and the one or more second clock sources;
translating, using the one or more offsets, one or more timestamps of one or more sensor measurements to a reference time domain; and
performing one or more operations for a machine using the one or more sensor measurements and the one or more timestamps translated to the reference time domain.
