This counter reports how many seconds have elapsed since this specific remote-access session was first established, giving a live running duration for that connection. It matters for spotting anomalies; an unusually long-lived session compared to typical usage patterns for that user population might indicate either a legitimate always-on use case or, in a security review context, a session that should have timed out but has not due to a misconfigured idle-timeout policy. An admin auditing active sessions and seeing one running for many days straight, well beyond typical workday usage, would want to confirm whether that reflects an intended persistent connection or a policy failure to properly terminate inactive sessions.
