function connectionsUpcomingList

Hi, i have 300 entries and i experiment a strange problem
all my birthday date are false by 2 days back.
Example : back office in birthday i put 10 september, and i get in my template shortcode <?php echo connectionsUpcomingList( array( ‘days’ => 15, ‘show_lastname’=>’true’, ‘date_format’=>’j F’, ‘template’ =>’birthday-light’ ) );?> 8 september
Strange no ?
How can i fix this issue ? Thanks
