title: How to add seconds(can go upto 10E12) to a datetime variable in python
body: <p>I am a newbie in python and I need to add a variable which has seconds in it to a datetime variable. </p>
  
  <p>The variable which has the seconds stored and the date to which it should be added looks like this. But couldnt get it correct as timedelta has only upto days.</p>
  
  <pre><code>sec_var = 1.83920792079208E+04
  print st_ti
  2013-01-01 00:00:00
  </code></pre>
  
  <p>Note: The sec_var can go upto 10(pow)12 which means I need to take care till years.</p>
  
  <p>So basically I need the seconds value to get added to the date variable. Please help me solve this. Thanks in advance</p>
