Do the Community pages have a metadata tag for the Date of the content on the page?  Something like date created or date modified for each page?

Hello - I am using Google Search Appliance (GSA) to crawl the Jive Community and display results in a separate application.  I would like to include the last modified date of the page as part of my search results.  Is there a DATE metadata tag that is consistent across all Community pages that I can try to pick up with GSA?
