title: Time difference with hours, minutes and seconds in SQL Server
body: <p>I need to find time difference between two columns with hours, minutes and seconds.  </p>
  
  <p>These are two datetime columns in my table:</p>
  
  <pre><code>STOP_TIME                      Start_Time
  ------------------------------------------------------
  2016-05-10 03:31:00.000        2016-05-10 02:25:34.000
  </code></pre>
  
  <p>I calculated second difference for stoptime and starttime. 3926 is the second difference. </p>
  
  <p>I need to convert this to time format <code>hh:mm:ss</code>. </p>
