title: ActiveRecord SQL execution time
body: <p>How can I get the SQL query execution time in rails?
  I can see the time in logs, e.g.:</p>
  
  <pre><code> Posting Load (10.8ms)  SELECT "postings".* FROM "postings" ORDER BY "postings"."id" ASC LIMIT 1
  </code></pre>
  
  <p>But how can I get that value (10.08) programmatically to use it further in my code?</p>
