This is a small modification for p4a default mask.
Open /p4a/themes/default/mask/default/default.php find <div id="p4a_footer">
and add the following code before.
In your P4A Class you can add the code:
$this->build("P4A_Box", "status_bar_box");
$this->box_stick->setHtml("<strong>".date("d/m/Y")."</strong><strong>IP:</strong>".$_SERVER['REMOTE_ADDR']);
Then in your P4A_Mask:
$this
->display("menu", P4A::singleton()->menu)
->display("status_bar", P4A::singleton()->status_bar_box);
Example of result:
