<h2>a jQuery plugin</h2>
<h3>What?</h3>
<p>
Timeago is a jQuery plugin that makes it easy to support automatically updating fuzzy
timestamps (e.g. "4 minutes ago" or "about 1 day ago"). <a href="jquery.timeago.js">Download</a>, view
the examples, and enjoy.
</p>
<p class="example">
You opened this page <abbr class="loaded timeago">sometime before now <span class="help">(turn on javascript, loser)</span></abbr>. <span class="help">(This will update every minute. Wait for it.)</span>
</p>
<p class="example">
This page was last modified <abbr class="modified timeago">sometime before now <span class="help">(turn on javascript, loser)</span></abbr>.
</p>
<p class="example">
Ryan was born <abbr class="timeago" title="1978-12-18T17:17:00Z">Dec 18, 1978</abbr>.
</p>
<h3>How?</h3>
<p class="how">
First, load <a href="http://jquery.com/">jQuery</a> and the plugin:
</p>
<pre>
<script src="jquery.min.js" type="text/javascript"></script>
<script src="jquery.timeago.js" type="text/javascript"></script></pre>
<p class="how">
Now, let's attach it to your timestamps on DOM ready:
</p>
<pre>
jQuery(document).ready(function() {
jQuery('abbr[class*=timeago]').timeago();
});</pre>
<p class="how">
This will turn all <tt>abbr</tt> elements with a class
of <tt>timeago</tt> and an <a href="http://en.wikipedia.org/wiki/ISO_8601">ISO 8601</a> timestamp in the title:
</p>
<pre>
<abbr class="<em>timeago</em>" title="<em>2008-07-17T09:24:17Z</em>">July 17, 2008</abbr></pre>
<p class="how">
into something like this:
</p>
<pre>
<abbr class="timeago" title="2008-07-17T09:24:17Z"><em>6 hours ago</em></abbr></pre>
<p class="how">
As time passes, the timestamps will automatically update.
</p>
<h3>Why?</h3>
<p>Timeago was originally built for use with <a href="http://yarp.com">Yarp.com</a> (coming soon) to timestamp comments.</p>
<ul>
<li>Because timeago can refresh automatically, you won't have timestamps dated "1 minute ago" even though the page was opened 10 minutes ago.</li>
<li>Because the fuzzy timestamps aren't calculated on the server, you can take full advantage of page caching in your web applications.</li>
<li>You get to use <a href="http://microformats.org/">microformats</a> like the cool kids.</li>
</ul>
<h3>Who?</h3>
<p>
Timeago was built by <a href="http://ryan.mcgeary.org">Ryan McGeary</a>
while standing on the shoulders of giants. John Resig wrote about
a <a href="http://ejohn.org/blog/javascript-pretty-date/">similar
approach</a>. The verbiage was based on
the <tt>distance_of_time_in_words</tt> ActionView helper
in <a href="http://rubyonrails.org">Ruby on Rails</a>.
</p>
<h3>When?</h3>
<p class="last">
Timeago was conceived <abbr class="timeago" title="2008-07-17T02:30:00-0500">on July 17, 2008</abbr>. <span class="help">(Yup, that's powered by timeago too)</span>
