Query Explanation

The rule triggers when the clock offset (node_timex_offset_seconds) stays beyond ±0.05 s and is not moving back toward zero: either the offset is > 0.05 s and its 5‑minute derivative is ≥ 0, or it is < ‑0.05 s and its derivative is ≤ 0. In either case the host’s clock remains out of sync, causing the alert.
