title: Add one day to DateTime.UtcNow
body: <p>I am trying to figure out how to add one  day to the current datetime for comparison later. I want to be able to turn of a feature in my app for one day if a user click on a button. So when the set datetime+24 hours is lower than the current datetime it will reactivate.</p>
  
  <p>I know how to get the current datetime like this:</p>
  
  <pre><code>static DateTime now = DateTime.UtcNow;  
  </code></pre>
  
  <p>But I want to do this:</p>
  
  <pre><code>static DateTime deactivateDate = DateTime.UtcNow+24;
  </code></pre>
  
  <p>Any help is appreciated :-)</p>
