relative date by Levani plugin

I installed easy relative date plugin on my wp installation and everything is fine. Plug in works ok but has problem tracking seconds…

Better:

If I add a news, then in the date field should appear 1 second ago, 2 seconds ago, etc… instead, the plugin shows something like -2589 second ago, -2128 seconds ago and so…. I tried to hard coding easy_relative_date.php but without success.

Here is the code of easy_relative_date.php im’ currently using:

?<?php

load_plugin_textdomain('erd', PLUGINDIR.'/'.dirname(plugin_basename(__FILE__)).'/languages');

if(!function_exists('easy_relative_date')){
        function easy_relative_date($timestamp){
            $difference = time() - $timestamp;
            if($difference >= 60*60*24*365){        // if more than a year ago
                $int = intval($difference / (60*60*24*365));
				$r = printf(__ngettext("%d anno fa", "%d anni fa", $int, 'erd'), $int);
            } elseif($difference >= 60*60*24*7*5){  // if more than five weeks ago
                $int = intval($difference / (60*60*24*30));
                $r = printf(__ngettext("%d mese fa", "%d mesi fa", $int, 'erd'), $int);
            } elseif($difference >= 60*60*24*7){        // if more than a week ago
                $int = intval($difference / (60*60*24*7));
                $r = printf(__ngettext("%d settimana fa", "%d settimane fa", $int, 'erd'), $int);
            } elseif($difference >= 60*60*24){      // if more than a day ago
                $int = intval($difference / (60*60*24));
              if ($int == 1) {
                $r = _e("Ieri", 'erd');
            } else {
				$r = printf(__("%d giorni fa", 'erd'), $int);
            }
            } elseif($difference >= 60*60){         // if more than an hour ago
                $int = intval($difference / (60*60));
                $r = printf(__ngettext("%d ora fa", "%d ore fa", $int, 'erd'), $int);
            } elseif($difference >= 60){            // if more than a minute ago
                $int = intval($difference / (60));
                $r = printf(__ngettext("%d minuto fa", "%d minuti fa", $int, 'erd'), $int);
				}
             else                                //count seconds
            {
                $s = $difference >= 1 ? 's' : '';
				$r = printf(__ngettext("%d secondo fa", "%d secondi fa", $difference, 'erd'), $difference);
            }

        }
    }

	?>

Any idea how to fix this problem? Thany you!
