Title changed from Fixes custom filter deletion for non admin user to Fixes #1533 (closed) date format issue and #706 (closed) Privilege for admin user to delete shared list

mentioned in commit 8694883c

Status changed to merged

I think problem always exist with date format like dd/mm/yyyy. My changed for this is to store initial value of date (before modification) in ivalue and use it like `insert_date = DateTimeField::convertToDBFormat($ivalue);` (line 1818)

DateTimeField::convertToDBFormat using user date format to convert, so it must receive date entered by user without alteration
