The AFTER operator can be very useful when you want to time the execution
of events in a playlist. An obvious example of this would be have banner text
appear at specific segments of a video. The example above shows how a banner
can be displayed exactly 15 seconds after a video starts, and another can be
displayed 30 seconds after the video starts.
Remember that it is important to include the AND operator in this situation as
well. Without it, the first banner would be displayed 15 seconds after the video
ends instead of 15 seconds after it begins.
NOTE: The maximum delay you can enter in the AFTER field is [06:59:59:59] .
This gives you a week of flexibility.
