title: How to find how long my rake task is taking
body: <p>I am using Rails 3.0.10 . I am using mac.</p>
  
  <p>I tried this</p>
  
  <pre><code>time  rake spec/models/user_spec.rb
  </code></pre>
  
  <p>Then I tried</p>
  
  <pre><code>time (rake spec/models/user_spec.rb)
  </code></pre>
  
  <p>This one took longer but I did not see my test output.</p>
  
  <p>What is the right way to figure out how long my rake is taking.</p>
