Widget within Panels-sidebar by "fossor coding"

Here is my email to Kustom support (I was redirected to this forum): I've tried to create a time-and-date widget within Panels-sidebar by "fossor coding". It went smoothly but the widget doesn't update time and date. Do you have any idea how to fix the issue? I fully understand that you are not obligated to support your product within others products but the Panels-sidebar is a very popular and convenient app and combination with KWGT gives good possibilities.
