Answer 1

您需要删除对mktime的调用中的第7个参数，并用date_default_timezone_set设置您的时区，然后PHP将为您处理夏令时。例如

date_default_timezone_set('Asia/Karachi');
$morningstarts = 9;
$eveningends   = 22;
$am7=mktime($morningstarts,0,0,$month,$day,$year);
$pm7=mktime($eveningends,$eveningends_minutes,0,$month,$day,$year);

Answer 2

    $timezone = 'America/Chicago';
    $morningstarts = 9;
    $eveningends = 22;
    $am7 = new \DateTime("@" . mktime($morningstarts, 0, 0, $month, $day, $year));
    $pm7 = new \DateTime("@" . mktime($eveningends, $eveningends_minutes, 0, $month, $day, $year));
    $am7->setTimeZone(new \DateTimeZone($timezone));
    $pm7->setTimeZone(new \DateTimeZone($timezone));

mktime（）最多期望6个参数，其中7个在
