One good indicator of web page health is its status in Google Webmaster Tools. Although I probably don't go there often enough, I do try to keep-up with warning it gives me. This time it was complaining about errors in my blog's markup.
Quick look into Google's Structured Data Testing Tool just confirmed that my blog's Suffusion theme was indeed missing proper information. How can I add it in?
Solution was rather easy once I found proper place. In ./wp-content/themes/suffusion/custom/post-header.php I found line that controls display of time:
<div class="date"><span class="month"><?php the_time('M'); ?></span> <span class="day"><?php the_time('d'); ?></span><span class="year"><?php the_time('Y'); ?></span></div>Since its original output was definitely not microformats compliant, I took simple step of extending it:
<div class="date value-title" title="<?php the_time('o-m-d'); ?>"><span class="month"><?php the_time('M'); ?></span> <span class="day"><?php the_time('d'); ?></span><span class="year"><?php the_time('Y'); ?></span></div>By putting value into title, I allowed Google and microformats to be happy and my theme kept its look&feel.
