Where this event sits in a trace, when its emitter places it in one (design 4.58): the span it is, that span's parent and when it started; the event's timestamp is its end. None for an event traced on its own. Only TraceEvent.CustomEvent, TraceEvent.TokenUsageRecorded, TraceEvent.ErrorOccurred and TraceEvent.AgentRunEnded carry one.
