Google BigQuery returns same value for visiId and visitStartTime
<p>I run this very simple query on BigQuery and it returned the visitId value as visit start time. Code is below and you can also see the screenshot here: <a href="http://i.stack.imgur.com/eE4eh.png" rel="nofollow">visitStartTime and visitId same value</a> </p>

<pre><code>SELECT visitStartTime, visitId FROM [83606741.ga_sessions_intraday_20160606] group by visitStartTime, visitId order by visitStartTime DESC;
</code></pre>

<p>How can I get the session start time to be shown like 11:45 and what is the reason these two columns have the same value?</p>

<p>Thank you for the replies!</p>
