Cache Time displays the time that the current page was cached, and prints it via the cache_time(); function. It takes into account the different time zones of the WordPress blog, and whether or not WP-Cache has blocked the current URL for caching.
It has been tested with WP 2.6 and WP-Cache only, so please contact me with any questions or concerns with other systems. WP-Super-Cache should work, but it is not officially tested.
Be sure to check out my other plugins at <a href="https://wordpress.org/extend/plugins/profile/wesg" rel="ugc">my WordPress profile</a>.
<h4>USAGE</h4>
<ol>
<li>Anywhere inside the WordPress template pages, copy <code><?php cache_time(); ?></code> to print the plugin’s output.</li>
</ol>
<h4>CUSTOMIZATION</h4>
There are 3 elements that can be customized with Cache Time:
<ol>
<li>Text displayed when page is cached — Open cache-time.php inside the Cache-time folder with your favorite text editor and find line 27 that says <code>$cached = 'Page cached on: ';</code>. Change the text between the quotes for your own message.</li>
<li>Text displayed if no cache is present — Similar to above, find line 29 that says <code>$not_cached = 'Time is now: ';</code> and change the text between the quotes.</li>
<li>Date Format — Again inside the cache-time.php file, line 36 can be changed to display your choice of information. More details about customizing the date can be found at <a href="http://www.w3schools.com/php/func_date_gmdate.asp" rel="nofollow ugc">w3schools</a>.</li>
</ol>
<h4>LIMITATIONS</h4>
<ol>
<li>Currently Cache Time only works with WP-Cache, though theoretically it should work with WP-Super-Cache as well.</li>
</ol>
