@PatrikS you will have to set the types precisely in some advanced settings and you might have to experiment a little bit.
If you have zoned date time variables the type to use is “TIMESTAMPTZ“:
In the DB Writer you then also set this type. You can also try to set it for groups of types of variables.
The data is then stored in Postgres as a Time variable with zone
You can check the type with another KNIME node
