title: How to add or subtract seconds from a datetime in DAX
body: <p>I have a datetime column and a int column representing a number of seconds. I'd like to calculate the sum of the two.</p>
  
  <p>For example:</p>
  
  <p>2017-08-01 18:00:00 + 180 (seconds) = 2017-08-01 18:03:00</p>
  
  <p>The DAX DateAdd function only supports adding a year/month/day and not seconds, so I'm stuck!</p>
