I know that by changing the meta description of my webpage, I can control the texts shown by Google in the search results. 

However I do not know how I can control the text shown just before the search results, for example the date when the page was last updated. Which meta tag to use to accomplish this?

**UPDATE:**
My webpage is automatically updated on a weekly basis on irregular intervals by a cronjob which makes changes to the MySQL database which holds the content of my webpages. So the question is what (meta) info to add to my page.
