The date should take its cue from the main Joomla language
(localised) php file setting. Alternatively the RSG2 config panel.
I don't think it should be hardwired into your template.

[display.class.php]

OLD
        Created: <?php echo mosFormatDate( $kid->date,"%d-%m-%Y" );?><br />

NEW
        Created: <?php echo mosFormatDate( $kid->date,"%Y-%b-%d" );?><br />

Personal opinion. YMMV
