Overview

The source time label carries the date and Eastern/Central zone; source estimation marks are preserved.

Query contract

Preserve one canonical row per (location_id, snapshot_time, location, state, time_label) before aggregating.

Analysis rules

  • For current state, select the latest complete snapshot_time per location_id from tva.feed_snapshots for this table. A row_count of zero means empty; never fall back to an older nonempty snapshot.

Interpretation

  • snapshot_time is collection time. Check the source day/time labels before describing data as current.
  • Raw strings preserve source units, missing-value sentinels and estimation marks; source_record retains all source fields.
