Query Explanation

The alert fires when the node’s clock has been out of sync for the entire last 5 minutes (min_over_time(node_timex_sync_status[5m]) == 0) and the measured maximum clock error is at least 16 seconds (node_timex_maxerror_seconds >= 16). In this case the host’s NTP is likely mis‑configured or failing, triggering the alert.
