Better timestamp explanation to the client

Hi, In one of our tables we have these fields: cust_no bigint(20), cust_name varchar(30), last_online datetime, and in that members profile, if someone visits it, on the top of the page we have this: // connect to db, query for record and display it below Last seen: <?php echo $last_online; ?> Any ideas on the simplest way to make it look like this: Last seen: Less than a minute ago! Last seen: 25 mins ago Last seen: 2 hours 11 mins ago Last seen: 1 (or 2 or 3) day/s ago else{ echo $last_seen; } I have seen this done on a few sites (Swedish sites actually, I can give you the URLs if you need them) I think it looks much better than: Last seen : 2005-09-07 20:59:01 Thanks!
