The inspect_columns result shows _ingestion_timestamp is a metadata column (all rows have the same value: 2026-08-11), not a data column representing when events occurred. I should check if there are any actual date/time columns in the data that would indicate a time period the dataset covers. Looking at the columns, I don't see any obvious date columns related to the Titanic voyage itself. Let me query to see if there are any temporal columns I might have missed, or confirm that this dataset has no time dimension.",
