CH column metadata: esios.indicators.datetime

Period start, tz-aware Europe/Madrid. Group with toStartOfHour/toDate (DST-correct, local hours). Per-row granularity is the catalog `frequency` (5min/10min/15min/Hora/Día/…); it can change over time (e.g. 600 went hourly→15min at 2025) — COUNT/AVG across the change are not comparable, normalize first. DST days are 23h/25h. See the MCP 'Time handling' instructions.
