Pandas: timestamp to datetime
<p>I have dataframe and column with dates looks like</p>

<pre><code> date
 1476329529    
 1476329530    
 1476329803 
 1476329805 
 1476329805  
 1476329805 
</code></pre>

<p>I use <code>df['date'] = pd.to_datetime(df.date, format='%Y-%m-%d %H:%M:%S')</code>
to convert that, but I'm get strange result</p>

<pre><code> date 
 1970-01-01 00:00:01.476329529   
 1970-01-01 00:00:01.476329530   
 1970-01-01 00:00:01.476329803  
 1970-01-01 00:00:01.476329805    
 1970-01-01 00:00:01.476329805   
 1970-01-01 00:00:01.476329805   
</code></pre>

<p>Maybe I did anything wrong</p>

<p>This looks look epoch timestamps which is number of seconds since 1st January 1970 :</p>
