title: TIMESTAMP and Standard SQL in Google BigQuery
body: <p>I am trying (and failing) to perform the following query in BigQuery using Standard SQL</p>
  
  <pre><code>SELECT
    user_id
  FROM
    dataset.table
  WHERE
    timestamp &gt; TIMESTAMP("2017-09-18 00:00")
  </code></pre>
  
  <p>I constantly get the message</p>
  
  <pre><code>Query Failed
  Error: Invalid timestamp: '2017-09-18 00:00'
  </code></pre>
  
  <p>I tried, desperate, with <code>2017-09-18T00:00</code> or like the Legacy SQL <code>timestamp &gt; "2017-09-18 00:00"</code> without success.</p>
  
  <p>Thanks for your help.</p>
