bulkUpsert в PHP SDK нормально не записывает Timestamp

$this->ydb->beginTransaction();
$this->ydb->createTable('test', [
    'id' => 'Uint64',
    'datetime' => 'Timestamp',
], 'id');
$this->ydb->bulkUpsert('test', [
    [
        'id' => 1,
        'datetime' => (new \DateTime())->format('c'),
    ],
], [
    'id' => 'Uint64',
    'datetime' => 'Timestamp',
]);
print_r($this->ydb->query('SELECT id, datetime FROM test'));

Выдаёт

YandexCloud\Ydb\QueryResult Object

    [columns:protected] => Array
        (
            [0] => Array
                (
                    [name] => id
                    [type] => UINT64
                    [options] => 
                )

            [1] => Array
                (
                    [name] => datetime
                    [type] => TIMESTAMP
                    [options] => 
                )

        )

    [rows:protected] => Array
        (
            [0] => Array
                (
                    [id] => 1
                    [datetime] => 1970-01-01 00:00:00
                )

        )

    [truncated:protected] => 
)

Как видно поле datetime равно 1970-01-01 00:00:00
