I have the following code:

$storeId = 1;
$attributesData = array("price" => $data['price'], 'updated_at' => date('Y-m-d H:i:s'));
    ->updateAttributes(array($data['product_id']), $attributesData, $storeId);

When I run this code, the price is updated but the updated_at column in catalog_product_entity is not (it does this regardless of update_at being in $attributesData).

I know I could just hammer in a quick little update query to update the date myself (and I will if I have to), but that is not the "Magento" way of doing things. I also do not want to load up the entire model just to save it. That would defeat the entire purpose of using what I call the "fast way" of updating products.

Any ideas?

I think it's because updated_at is a static attribute not a 'variable' EAV attribute. You can't save it as you did. You have to save it with the help of the Product model.

Mage_Catalog_Model_Product_Action::updateAttributes() call the method of the resource model Mage_Catalog_Model_Resource_Eav_Mysql4_Product_Action::updateAttributes() and in this method tries to get the attribute from the eav entity. But in the case of updated_at, it saves the attribute in a bad way. See below.

I tried your code and got an exception, I use Magento 1.5. You probably also have a silenced error. After debuggging, I saw the following sql query which is triggered when using your code:

INSERT INTO `mage_catalog_product_entity` (`entity_type_id`, `attribute_id`, `store_id`, `entity_id`, `value`) VALUES (?,?,?,?,?) ON DUPLICATE KEY UPDATE `value`=VALUES(`value`)

0   (string:1) 4    
1   (string:3) 498  
2   (int) 0 
3   (int) 303   
4   (string:19) 2013-01-30 15:47:00 

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'attribute_id' in 'field list'

The class Mage_Catalog_Model_Resource_Eav_Mysql4_Abstract and the method _saveAttributeValue show how the query is created:

$table   = $attribute->getBackend()->getTable();

     * If we work in single store mode all values should be saved just
     * for default store id
     * In this case we clear all not default values
    if (Mage::app()->isSingleStoreMode()) {
        $storeId = $this->getDefaultStoreId();
        $write->delete($table, join(' AND ', array(
            $write->quoteInto('attribute_id=?', $attribute->getAttributeId()),
            $write->quoteInto('entity_id=?', $object->getEntityId()),
            $write->quoteInto('store_id<>?', $storeId)

    $bind = array(
        'entity_type_id'    => $attribute->getEntityTypeId(),
        'attribute_id'      => $attribute->getAttributeId(),
        'store_id'          => $storeId,
        'entity_id'         => $object->getEntityId(),
        'value'             => $this->_prepareValueForSave($value, $attribute)

For me it's definitely not the way to save this attribute. Use the model instead. You will be sure of the result.
