For the format "Yesterday/Today, at 6:00 pm" in 2.2.8 (Probably the same for 2.2.9) I just changed this (In admin/functions.php):

PHP Code:

    if ($date==$todaydate) {
      $date="Today";
    }
    if ($date==$yestdate) {
      $date="Yesterday";
    } 


to this:

PHP Code:

    if ($date==$todaydate) {
      $date="Today, at";
    }
    if ($date==$yestdate) {
      $date="Yesterday, at";
    } 


Great Hack!
