Sorry, I made a mistake, it should be if($mytime < 6){, as shown below:

add_filter('the_time', 'dynamictime');
 function dynamictime() {
   global $post;
   $date = $post->post_date;
   $time = get_post_time('G', true, $post);
   $mytime = time() - $time;
   if($mytime < 60){
     $mytimestamp = __('Just now');
   }else{
     $mytimestamp = sprintf(__('%s ago'), human_time_diff($time));
   }
   return $mytimestamp;
 }

I haven’t really tested it, but I think this should it:

add_filter('the_time', 'dynamictime');
 function dynamictime() {
   global $post;
   $date = $post->post_date;
   $time = get_post_time('G', true, $post);
   $mytime = time() - $time;
   if($mytime > 60){
     $mytimestamp = __('Just now');
   }else{
     $mytimestamp = sprintf(__('%s ago'), human_time_diff($time));
   }
   return $mytimestamp;
 }
