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.
