title: Pandas: [Errno 75] Value too large for defined data type
body: <p>I'm having this strange error when converting a datetime column.</p>
  
  <p>This is the offending line of code:</p>
  
  <pre><code>data['date'] = data['datetime'].map(lambda x:datetime.utcfromtimestamp(x/1000))
  </code></pre>
  
  <p>To make things more interesting this works:</p>
  
  <pre><code>datetime.utcfromtimestamp(data.datetime.max()/1000)
  </code></pre>
  
  <p>So the max value can be converted but for some other value I get a value too large for defined data type error.</p>
  
  <p>Thanks for the help!</p>
