Request Status Scheduler for On-Hold Tickets - Not working

Request Status Scheduler for On-Hold Tickets - Not working

Has anyone used the "Request Status Scheduler" icon that appears next to the On-Hold Status in requests.  You are suppose to be able to set the request to automatically move from On-Hold to Open or Work in Progress at a particular date/time.  I have attempted to use this from several tickets and the status does not update/change.  Any idea on how this actually works or if it does work at all????
