title: Difference between two time.Time objects
body: <p>Very new to the 'Go'. Question might be basic one.</p>
  
  <p>I have two time.Time objects and I want to get the difference between the two in terms of hours/minutes/seconds. Lets say:</p>
  
  <pre><code>t1 = 2016-09-09 19:09:16 +0530 IST
  t2 = 2016-09-09 19:09:16 +0530 IST
  </code></pre>
  
  <p>In above case, since the difference is 0. It should give me 00:00:00. Consider another case:</p>
  
  <pre><code>t1 = 2016-09-14 14:12:48 +0530 IST
  t2 = 2016-09-14 14:18:29 +0530 IST
  </code></pre>
  
  <p>In this case, difference would be 00:05:41. I looked at the <a href="https://godoc.org/time" rel="noreferrer">https://godoc.org/time</a> but could not make anything out of it.</p>
