when has the website been updated last

<p>I was looking for something in the web. When I found and read it, I found out that the information was not actual. Maybe the admin forgot to update the website. But how could I see when the website has been updated last time?</p>

JavaScript makes it possible

after looking for some information I found a short JavaScript code in internet. javascript:alert(document.lastModified)  You just copy and put it into the adressbar. After click to enter you get a popup with the date of the last updating.
