Issue with date format when using derived-variables

[Seddryck]

If the initial text is 20191001_141542.xml, the value of timing will be evaluated to 2019-10-01 12:15:42 but the value of start is evaluated to 2019-01-10 12:15:00

<derived-variable name="timing" type="dateTime" based-on="file">
  <script language="native">
    path-to-filename-without-extension | text-to-dateTime(yyyyMMdd_HHmmss) 
    | local-to-utc(Brussels)
  </script>
</derived-variable>
<derived-variable name="start" type="dateTime" based-on="timing">
  <script language="native">
    dateTime-to-floor-minute | dateTime-to-add(00:30:00, -1)
  </script>
</derived-variable>

Checked and cannot reproduce. Could be linked to #529, will check further next week.

This should be checked further with the culture issues that were identified during the last month.
