Along with a host of other interface changes, the WordPress development team phased out the display of the exact time a post was modified after version 2.3, opting instead for an approximate time display. Many bloggers who rely on closely scheduling posts were unhappy with this change and made requests for it to be remedied.

The Restore Exact Time plugin was born out of the desire of a minority in the WordPress community. When activated, the plugin changes the time display for posts in the administrative interface to display the exact time they were modified. If you’re a blogger who frequently needs to know the time of their last post, then I recommend installing the Restore Exact Time plugin.
