How to Combine Social Marketing with our Scheduled Content plugin to create a limited-time offer?

So I saw the plug-in description: "Combine Social Marketing with our Scheduled Content plugin to create a limited-time offer!" And I really want to achieve that.
I have both plug-ins but have no idea how to create limited-time offer. The finial result I want will be a timer with the Social Marketing offer. So when the timer come to 0, the offer is ended. Like the reverse of Scheduled Content.

Please advice! Thanks !
