[Zope] [Beginner question] Date last revised

Hello, What way is there to refer to the last-modified date of a Zope document, from within it? Since it's displayed on the management page for a document, I'm sure it's accessible somehow, but so far guessing at names to use in <!--#var document-last-modified--> hasn't gotten me anywhere, and I don't see it listed in Properties. Am I overlooking it in one of those lists in the User Guide?
