System Calendar is a licensed feature that offers the ability to automate system tasks to occur at specific time each day, on a particular day or at regular intervals. A couple of useful examples are to schedule a full backup of the entire system at the end of each day. Or to automatically synchronize the controllers timestamps with that of the Application Server. When using other software features such as Global Linkage it is important that the timestamps are not out of sync because Global Linkage actions may then be executed at the wrong time.
