Embed scheduled content into your pages, posts and even custom post types supporting shortcodes.
Use [szbl_scheduled_content] to wrap and schedule your content. To hide content until a specific date, use the start attribute. To have content expire, use the end attribute:
[szbl_scheduled_content start="Jan 1, 2013 12am" end="Apr 14, 2013 12:00pm"]This is my scheduled content[/szbl_scheduled_content]
You can enter dates/time in any standard format and the plugin should interpret them correctly, using the timezone set under Settings > General.
