> Computing a MAX or MIN of a TIME column using the OVER clause seem to generate wrong results compared to Postgres. Example of such queries:
> {noformat}
> SELECT MIN(cast( columns[8] as TIME )) OVER(PARTITION BY cast( columns[2] as CHAR(2)) ORDER BY cast( columns[0] as INT )) FROM `allData.csv`;
> {noformat}
> SELECT MAX(cast( columns[8] as TIME )) OVER(PARTITION BY cast( columns[2] as CHAR(2)) ORDER BY cast( columns[0] as INT )) FROM `allData.csv`;
> {noformat}
> {noformat}
