title: add 2 hours in current time in Python and print the time in timestamp
body: <p>How to get the <strong>current time</strong> and return that in <strong>timestamp</strong> format after adding <strong>2 hours in it</strong> like <strong>1535020200000</strong></p>
  
  <p>i tried the following but I am not getting the expected result</p>
  
  <pre><code>current_time + timedelta(hours=2)
  
  (datetime.now()).split('.')[0] + timedelta(hours=2)
  </code></pre>
  
  <p>since the second one returns a string, addition operation cannot be done</p>
