Reports -> Run time parameter does not work


I am trying to populate a simple reports on listing all the leads of Past.

However. when I am trying to run time parameter of date created of lead less than with date value of today, it does not display any result.

In the error log I get the message

  • convert: Conversion of 09/30/2015 00:00:00 from Y-m-d H:i:s to m/d/Y failed


Would you be able to provide screenshots of the Report’s EditView and Detailview?
Also, a screenshot of the Date_created for an example Lead Record would be useful too.
