A WordPress Plugin will displays the Last Updated Date & Time in your posts instead of creation date

Last Updated DateTime in Posts

Most of the WordPress themes don't have the feature to display the modified date on posts. Instead of this they simply display the post published date. It will seem it is an archived post to the visitor. With the help of this plugin, I could display the Last Modified Date on my posts. Really helpful! But more settings and date formats will make this plugin awesome.
