<!-- Answer --> In Superset, is_temporal is a property that marks whether a column represents temporal (date/time) data. It's used to identify columns that can be used for time-based filtering, grouping, and visualizations. Technically, is_temporal is determined either by an explicit flag (is_dttm) or by inferring from the column's data type—if the type matches a recognized temporal type, is_temporal is set to true. This property is important because time-based features in Superset (like time filters in charts) require at least one column to be marked as temporal. If your columns have ambiguous or unsupported types (like NULLABLE or UNKNOWN), Superset may not recognize them as temporal, which can cause errors during dataset sync or when building time-based charts ([source](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/connectors/sqla/models.py), [source](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/result_set. py)). <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
