Turn ISO 8601 date/time into "x minutes ago" type of string
<p>So I have an ISO 8601 date/time stamp like "2011-04-21T17:07:50-07:00", and I would like to convert it to say something like "23 minutes ago" or something of that sort. Is there a small bit of Java code or a library that would be able to do something like that easily?</p>

<p>Thanks!</p>
