The pInfo.Timestamp is refreshed but the sort in activeQ or podBackoffQ is not be updated when pod is already present in the backoff or active queue.
AddUnschedulableIfNotPresent() return error if pod is already present in the backoff or active queue, and there is no re-add.
So refresh pInfo.Timestamp when the pod is not present in the three sub-queues, otherwise need to update the order of the pod in the active or backoff queue, for example p.activeQ.Update(pInfo)
