This is a text timestamp recording when an operator or the system last zeroed the 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 in the rolling 24-hour bucket for the current day, still accumulating until the day boundary rolls it into history, distinct from when the bin itself started. Because this bin is still actively filling, a recent value here warns you that its ingress rate-policing counters were reset only moments ago and have not yet had the full 24-hour window to accumulate, so a low reading right now says nothing about whether traffic has actually been light. For example, if the bin's start time is 09:00 but this cleared-time reads 09:25, any ingress rate-policing count you read at 09:26 only reflects one minute of traffic, not the twenty-five minutes you might assume.
