+ * Automatic fix online time procedure. If a user has been idle for $timeLimit
+ * or more then the procedure adds $extraTime to his logout_course_date.
+ *
+ * How to use it:
+ *
+ * By default the script will fix only users with teacher status (COURSEMANAGER)
+ *
+ * php main/cron/fix_online_time.php
+ *
+ * If you want to add an specific status you can call the file with:
+ *
+ *  php main/cron/fix_online_time.php status=5
+ *
+ * Where "5" is the value of the 'STUDENT' constant.
