This was based on <a href="http://lesterchan.net/wordpress/readme/wp-relativedate.html" title="Relative Date" rel="nofollow ugc">Lester Chan’s Relative Date plugin</a>. 
It tries to simplify things a bit. This plugin can:
<ul>
<li>Replace the_date() in the post</li>
<li>Replace get_comment_date() or comment_date() in the comments</li>
</ul>
Note that if your theme is writing the date in a different form, it won’t work. You have to 
replace its function call to one of the above (in the TwentyTen theme for example, replace twentyten_posted_on() 
by the_date().
Also important to say that, comment replacement won’t work if you are using the default wp comment renderer because 
it calls get_comment_time() as well. You have to do a customized callback function to use with 
wp_list_comments( array( ‘callback’ => ‘your_customized_function_here’ ) ). (ok, maybe things were not 
simplified that much :/)
There is a options page (under settings in the Admin) where you can choose which dates you 
want to replace (posts/comments). Posts date are by default checked.
Portuguese translation included.

Simple Relative Date

A simple way to turn your post/comment date in its relative versions.

Simple Relative Urls plugin changes:
<ul>
<li>home and siteurl</li>
<li>script src urls</li>
<li>style link urls</li>
<li>images src urls</li>
</ul>
It uses wordpress filters. 
It doesn’t interact with database. 
It is fast, it doesn’t search and replace generated html. 
It doesn’t change hardcoded urls (for example in post content). 
It is flexible.
Plugin was originally created to enable wordpress to work with a <a href="https://www.npmjs.com/package/localtunnel" rel="nofollow ugc">localtunnel</a> npm package
<blockquote>
localtunnel exposes your localhost to the world for easy testing and sharing! No need to mess with DNS or deploy just to have others test out your changes.
</blockquote>
<h3>Example use cases</h3>
If Your development tasks don’t involve images, don’t download them from a server. Just install the plugin and add this line of code to your wp-config.php file
<pre><code>define( 'SRU_IMG_SRC_RELATIVE', false );
</code></pre>
Your local copy will then display images from their oryginal source.

Simple Relative Urls

This plugin makes urls (home url, js, css, images) across website relative. Works great with localtunnel npm package.
