ACF按日期时间字段排序，即将发生的事件不起作用

Question

我正在尝试使用ACF DateTime选择器字段提取WordPress中即将发生的事件的列表。

我认为应该是一套相对简单的$args令我困惑，为什么它不起作用：

$args = [
 "post_type" => "event",
 "post_status" => "publish",
 "posts_per_page" => 3,
 "order" => "ASC",
 "orderby" => "meta_value",
 "cat" => implode(',', $category),
 "meta_query" => [
   [
    "key" => "event_start_date_and_time",
    "compare" => ">=",
    "value" => date('U'),
    "type" => "DATETIME"
   ]
],
"meta_key" => "event_start_date_and_time",
"meta_type" => "DATE"
];

这是带通事件，但并非所有事件都按开始日期时间的ASC顺序排列。

我缺少明显的东西吗？

ACF DateTime Picker字段将日期存储在数据库中，如下所示

以下代码正在运行其经过测试的代码。

        $posts = array(
         "post_type" => "product",
         "post_status" => "publish",
         "posts_per_page" => 3,
         "order" => "ASC",
         "orderby" => "meta_value",
         "cat" => implode(',', $category),
         "meta_query" => (
         array (
            "key" => "evntdate",
            "compare" => ">=",
            "value" => date('U'),
            "type" => "DATETIME"
           )
        ),
        "meta_key" => "evntdate",
        "meta_type" => "DATETIME"
        );
        $posts=get_posts($posts);
