Shows when the document was last modified
This script is to easily see the time a document was last modified. It relies on the document.lastModified javascript property. It also checks for a sitemap.xml and surfaces a link. These are the two easy ways of seeing when a webpage was last modified. To check out the limitations of document.lastModified, read the link here: https://www.oreilly.com/library/view/javascript-the-definitive/0596000480/re198.html
