How to set an OR condition in a filter?

Question

1C-Bitrix

It is necessary to select elements with filled PROPERTY_TIME outside the period $from, $to and with empty PROPERTY_TIME. I did this, but it returns an empty selection, although there are such elements. So I understand that he joins the conditions through AND, but how to set OR?

$arFilter = Array(
        "IBLOCK_ID" => $iblock_id,
        "SECTION_ID" => $section_id,
        "INCLUDE_SUBSECTIONS" => "Y",
        "<PROPERTY_TIME" => array(false, date('Y-m-d H:i:s', $from)),
        ">PROPERTY_TIME" => array(false, date('Y-m-d H:i:s', $to)),
    );

    $elList = new CIBlockElement();
    $rs = $elList->GetList(
        Array("RAND" => "ASC"),
        $arFilter,
        false,
        Array("nTopCount" => 5),
        Array("ID", "NAME")
    );
