Formula used to separate leading "1" and "0" from date string ("Sep1" and "Date 2"), to determine a start of full year ("19" for "0" or "20" for "1") and to combine "Start of Year" with Date 2" into "Correct Date".
date Sep1 Date 2 Start of Year Correct Date 1040202 1 0400202 20 20040202
DateTime to convert the "Correct Date" to a data field. Select ... to select only the needed ones :).
