Package io.opentelemetry.instrumentation.api.instrumenter

Interface TimeExtractor<REQUEST,RESPONSE>

public interface TimeExtractor<REQUEST,RESPONSE>

Extractor of the start and end times of request processing.

Note: if metrics are generated by the Instrumenter, the start and end times from the TimeExtractor will be used to generate any duration metrics, but the internal metric timestamp (when it occurred) will always be stamped with "now" when the metric is recorded (i.e. there is no way to back date a metric recording).
