ABSTRACT:
An event logging system in which logged events are time stamped by storing a value read from a counter which is incremented at an arbitrary but consistent rate. When the data is recalled for analysis, the actual time of the event is calculated by reading the current value of the counter, reading the stored counter values associated with logged events, measuring the period of the clock incrementing the counter, and then using this information to calculate the absolute time.
