title: Python error : TypeError: Object of type 'Timestamp' is not JSON serializable'
body: <p>I have a Dataframe that has a time stamp column of type 'datetime64[ns]'. When I try to insert it to Salesforce platform get an error '<strong>TypeError: Object of type 'Timestamp' is not JSON serializable</strong>'. How could I change this timestamp column to have it updated properly. Given below is the view of the Dataframe.</p>
  
  <pre><code>Id,Name,Date,Type
  1,ProdA,2018-05-18 04:45:08,S
  1,ProdB,2018-05-18 02:15:00,S
  1,ProdC,2018-05-16 10:20:00,S
  </code></pre>
  
  <p>Datatype for each of these 4 columns:</p>
  
  <pre><code>Id                                     object
  Name                                   object
  Date                           datetime64[ns]
  Type                                   object
  dtype: object
  </code></pre>
  
  <p>Could anyone assist on this. Thanks.</p>
