Sometimes when you update one of your pages on the WordPress blog you would want visitors to know about those. This widget will create a sidebar 
box with a list of pages you’ve recently updated. It also shows the date of the update beside the page title. You can choose whether to display the update date and in what format.
You’ve an option to display the Posts in the list as well. If checked (through admin panel) the list will include the Posts along with the list of Pages.
You can use WP’s shortcode to display the last update date of the page or blog posts. Date/time format for the shortcode can be controlled through the widget settings.
V 1.0.4 only fixes the bug related to the widget area where any widget (in admin panel) below RUP’s widget will lockup and cannot be moved.
V 2.0.0 widget code updated to make it combatible with WordPress v. 6.6.2

The Last Modified date is used to tell the readers and search engine bots (Google, Yahoo!, Bing etc.) when webpage is updated lastly. People will know the freshness of that web document, and Web crawlers can also decide, whether there’s any need to save a new copy of that webpage to update their indexes, or not.
You will also be able to add Revised Meta data to your posts and pages through this plugin, but that is completely optional.

<pre><code>&lt;meta name="revised" content="Sunday, April 21, 2013, 2:59 am" /&gt;
