Date Time Format

[DrNatsu]

I'm encountering an issue with Apache Superset when working with a TIME data type that includes microseconds. In my database, I have a TIME column (departure_time) that is correctly stored and displayed in the format HH:MM:SS.ffffff. However, when I attempt to use this column in Superset, I'm seeing unexpected behaviors such as NaN values and incorrect timestamp interpretations.

Specifically:

1. Superset recognizes the column as TIME, but attempts to specify a format (e.g., %H:%M:%S) in the "Datetime Format" field result in an "Invalid date/timestamp format" error.
2. Even without specifying a format, the column does not render correctly in visualizations.
3. Casting the TIME to a simpler format or VARCHAR resolves the issue, but this seems like a workaround rather than a solution.
