title: Why CakePHP forms INSERT statement with 'CURRENT_TIMESTAMP' in quotes?
body: <p>I'm getting this error, because cakephp 1.3.11 creates an INSERT statement with 'CURRENT_TIMESTAMP' in quotes. Similar thing worked in 1.3.9. What might I be doing wrong?</p>
  
  <pre><code> SQL Error: 1292: Incorrect datetime value: 'CURRENT_TIMESTAMP' for column 'time_posted' at row 1 [CORE\cake\libs\model\datasources\dbo_source.php, line 684]
  </code></pre>
  
  <p>This is the context query:</p>
  
  <pre><code>$sql    =   "INSERT INTO `my_table` (`time_posted`, `version`, `provider`, `date`) VALUES ('CURRENT_TIMESTAMP', 0, 'provider', '2011-08-03 16:11:00')"
  </code></pre>
  
  <p>I'm trying to create a new record in database from cakephp using this code:</p>
  
  <pre><code>class MyTable extends AppModel
  {
  ...
  function blah() {
  ...
  $this-&gt;create()
  $ret=$this-&gt;save(array('MyTable'=&gt;array('provider'=&gt;$provider,'date'=&gt;$datetime)));
  ...
  </code></pre>
  
  <p>here's the stack:</p>
