The Notification display time field determines how long the notification is shown on a page. The default display time is 10,000 milliseconds, which means that the notification is shown for 10 seconds. To convert seconds to milliseconds, multiply the number of seconds with 1000. For example:
2,5 seconds = 2500 milliseconds;
5 seconds = 5000 milliseconds;
8 seconds = 8000 milliseconds.
