title: what is the format of this timestamp - "1369158405"?
body: <p>What is the timestamp format for this - <code>"1369158405"</code>? </p>
  
  <p>This link <a href="http://www.timestampgenerator.com/" rel="nofollow">http://www.timestampgenerator.com/</a> provides such formats but I could not find any information on the format name. </p>
  
  <p>I am also curious to know how such a timestamp is calculated to generate a format of type <code>"1369158405"</code> for <code>"Tue May 21 17:46:45 2013 GMT"</code>? Is there any function that creates such time stamps in C#?</p>
