Research direction

Start by reproducing the reported alert criterion with InfluxDB v13 and Kapacitor 1.0 beta, using the timestamps and values from the issue. Trace how hour("time") is evaluated and verify whether alerts can occur at 01:05 or 01:35; done means identifying the cause and documenting or correcting the observed behavior.
