This is a text timestamp recording exactly when the general life-to-date running counter for this metric, which an operator can zero with a manual clear -- which is why a clear-time field is defined alongside it began collecting its ingress traffic on this service classified as accepted (in-profile), yellow (remarked, over the committed rate but under the excess rate), or dropped (over the excess rate), plus live receive-rate gauges. On this element it is the anchor you need before trusting any of the accompanying ingress rate-policing counters reported alongside it in this same bin, since without it you cannot tell whether a given count covers everything accumulated since the last manual clear or some other span entirely. For example, a start time of 2026-08-06 09:15 on this Stats bin tells you every ingress rate-policing counter reported with it only reflects activity from that moment forward, not anything that happened earlier.
