Google PHP客户端库“全天”事件重复

这是我的密码

    if($service instanceof Google_Service_Calendar and isset($_SESSION['service_token']) and $_SESSION['service_token'] != '' ) {
                        $event = new Google_Service_Calendar_Event();
                        $event->setSummary('AllDay Event Bug');
                        $start = new Google_Service_Calendar_EventDateTime();
                        $start->setDateTime(date('Y-m-d\TH:i:s',strtotime('2015-11-11 10:00:00')));
                        $start->setTimeZone('Australia/Melbourne');
                        $event->setStart($start);
                        $end = new Google_Service_Calendar_EventDateTime();
                        $end->setDateTime(date('Y-m-d\TH:i:s',strtotime('2015-11-16 11:00:00')));
                        $end->setTimeZone('Australia/Melbourne');
                        $event->setEnd($end);
                        if(recurring) {

                            $recurrenceUntil = date('Ymd\THis\Z',strtotime('2015-11-16 11:00:00'));

                            if(count($exDateArr) > 0) {
                                $exdate = "EXDATE:".implode(",", $exDateArr);
                            } else {
                                $exdate = '';
                            }


                            switch ($repeate) {
                                case "day":
                                    $frequence = "DAILY";
                                    break;
                                case "week":
                                    $frequence = "WEEKLY";
                                    break;
                                case "month":
                                    $frequence = "MONTHLY";
                                    break;
                                case "year":
                                    $frequence = "YEARLY";
                                    break;
                            }

                            $event->setRecurrence(
                                array(
                                    "RRULE:FREQ=".$frequence.";UNTIL=".$recurrenceUntil.";INTERVAL=".$repeate_interval,
                                    $exdate
                                )
                            );

                        }

                        $newEvent = $service->events->insert('primary', $event);

}

当我在谷歌日历中搜索该事件时，这就是我得到的结果

第一天一切都很好，第二天又增加了一个额外的全天活动，并且每天都在增加。有人能告诉我为什么会发生这种情况吗？ 我正在使用Google服务帐户凭据，我添加的事件不是重复发生的事件，也没有例外日期
