Abstract: In one embodiment, an event processing system includes a clock configured to provide time values, and event processing circuitry, which is configured to generate a confidence level indicative of a degree of confidence of an accuracy of a timestamp, the timestamp being generated for an event responsively to a time value indicative of when an operation associated with the event occurred.
