Group:DateTime:MIN not displayed in sitemap

Setup, Configuration and Use Items & Sitemaps

Thanks for the help!
I did it like this:

In the rule I changed to

item.postUpdate(now.millis);

Group:Number:MIN gLastSeen “Last Seen [JS(millisToDate.js):%s]” (gHome)

(function(i) {
       return new Date(parseInt(i)).toString();
})(input)
