When using negative values to calculate the difference between two dates with gs.dateDiff() ,the day value is not shown

Example scenario:

1. Open any Change Request record.
2. Right-click the form header and select Configure > Form Layout.
3. Create a new field called Date Difference with a type of Duration.
4. Create a Before insert/update business rule on Change Request table to calculate the Date Difference with following script:
   current.date_difference = gs.dateDiff(current.start_date.getDisplayValue(), current.end_date.getDisplayValue(), false);
5. Open an existing Change Request record (or create a new one) and put a Planned Start Date later than a Planned End Date.
   Ensure the number of Days is negative (the Date Difference value should be negative).
6. Navigate to change_request.list.
7. Personalize the List Layout adding the Date Difference column.
   Note that the negative day value is not present, only the hour/minute values are displayed.

Negative values are currently not supported.
