The inspect_columns result shows _ingestion_timestamp is constant (all rows have the same timestamp: 2026-08-11 23:14:58.167121+00), so that's not a data time period. I should check if there are any other date/time columns that might indicate when the Titanic data itself is from, or if this is purely cross-sectional data without a time dimension.",
