Timing is important. We look at watches and clocks often throughout the day, as most of us have a busy schedule. With websites, it is often advantageous to know when the current page has been written or created.
That is why I have written this simple WordPress plugin for websites. At first glance it appears to be a basic plugin that displays the current time, but there is much more behind the scenes.
Cache Time displays the time that the current page was cached, or, if the page is not part of the caching system, it shows the current time. It is smart enough to take into consideration the time zone of the WordPress installation, and it checks the WP-Cache configuration file for any URLs that are not supposed to be cached. My website is currently displaying this information in the footer.
Tested up to the latest version of WordPress, 2.6.
