Each posting has a sunrise and a sunset date. The AgCenter CMS will automatically place the date and time that the posting was created as the sunrise date. This is the moment when the create article button was clicked. The Sunset date should be set to one year after the sunrise date. One year is the maximum amount of time allowed before a posting must be reviewed and re-submitted or expired.

When a posting reaches the sunset date, it is removed from the public’s view of the site. It is, however, still available through the archive manager for the channel in which it was posted. The author of the posting is notified via E-mail of the expiration and is given the option to re-submit the posting for continued publication if the content is still valid and valuable.
