This code uses Senocular SWFReader class to get the modification (publish) date of the SWF, and then displays it as a right-click menu item. You need to make sure that your SWF includes the XMP metadata. In the Flash IDE you can turn this on by going to Publish Settings > Flash > Include XMP metadata.
