@JohnnyRocks, as @steven-matison said, you should avoid linking so many ReplaceText. I am not quite sure I understood your flow exactly, but something tells me that before reaching ReplaceText, something is not properly configured in your NiFi Flow. First of all, when using the classic Java Data Format, MM will always transpose in a two digit month, meaning that month from 1 to 9 will be automatically appended with a leading zero. "dd" will do the same trick but for days. As I see in your post, you said that your CSV reader is configured to read the data as MM/dd/yy, which should be fine, but somehow something is missing here ---> How do you reach the format of dd/MM/yyyy? What I would personally try to do is to convert all those date values in the same format. So instead of all those ReplaceText, I would try to insert an UpdateRecord Processor, where I would define my RecordReader and my RecordWritter with the desired schemas (make sure that your column is type int with logicaly type date). Next, in that processor, I would change the Replacement Value Strategy into "Record Path Value" and I would press on + and add a new property. I would call it "/Launch_Date" (pay attention to the leading slash) and I would assign it the value " format( /Launch_Date, "dd/MM/yyyy", "Europe/Bucharest") " (or any other timezone you require -- if you require your data in UTC, just remove the coma and the timezone). ...
