When importing date columns from Redshift into Quick Sight, the system often converts them to timestamp format with trailing zeros (00:00:00). If i am not mistaken, This is a known behavior in Quick Sight when handling date fields.
To fix this issue when exporting to CSV, you can create a new calculated field using the formatDate function with the formula: formatDate({your_original_date_column}, ‘yyyy-MM-dd’).
This new field will be a string type containing only the date in the YYYY-MM-DD format without the time component.
