Hi Alex, This is the joinExisting aggregation on time listed below? I'm not sure if there is a way to configure the aggregation so the time coordinate is not converted to ISO string values. I'm guessing not but I will double check. Can you send us some example datasets so we can look into why the time dimension is not the right size?
