title: What's the function of the Publish field of items in Sitecore
body: <p>I am wondering what the function is of the Publish field of items in Sitecore. Just to be sure I am clear about what field I am talking about it's the field in the "Publishing" section of an item which is only shown when you check the "Standard fields" option.</p>
  
  <p>Normally that field is not filled in and I expected it to be filled automatically by Sitecore when an item is published due to it's publishing restrictions settings but I am no longer sure about this.</p>
  
  <p>Regards,</p>
