insert date

Hi,

I'm trying to insert the current date into a mysql table and I'm doing something wrong.

Code:

$input = array(
    'title'            => $title,
    'description'             => $desc,
    'tag'             => $tag,
    'attachment'            => $file,
    'max'            => $max,
    'date'            => 'NOW()'
    );
$this->db->insert('some_table',$input);

The other variables are well inserted. The date field is "datetime" and remains null. What am I missing? Thanks!
