title: How to display the time with 'hours:minutes:seconds' in Rails 3?
body: <p>I was spending lot of time for the answer of my question, but I've nothing found.</p>
  
  <p>How can I display the time format in 'hours:minutes:seconds', ex.: 20:30:12? I've tried to change the locale from >time: "%H:%M"&lt; to >time: "%H:%M:%S"&lt; because I saw that %S is for seconds, but there is no effect :(</p>
  
  <p>What I've done wrong?</p>
  
  <p>Thanks for answers!</p>
