Thanks, yes I see that too.
I then, as a workaround, use an SQL task to convert the 43191 number to a date format I need:
select REPLACE(CONVERT(VARCHAR,CAST(CAST(({TASK(PrevTask,StdOut)} -2) AS DATETIME) AS DATE), 113),' ','-')
Result: '13-Sep-2019'
Messy, but let's me move on in my development.....
Many thanks
