@thentangler it seems for the transfer of data from python to KNIME not all data types are supported in all nodes. One option could be too convert to an older python time format.
One option could be to store the data as a text column and convert it later. Not the most elegant solution I know.
Next thing would be to export the data from within three python node to a file or local database like SQLite or H2 and see if they would support the time format.
