title: Displaying AM and PM in lower case after date formatting
body: <p>After formatting a datetime, the time displays AM or PM in upper case, but I want it in lower case like am or pm.</p>
  
  <p>This is my code:</p>
  
  <pre><code>public class Timeis {
      public static void main(String s[]) {
          long ts = 1022895271767L;
          String st = null;  
          st = new SimpleDateFormat(" MMM d 'at' hh:mm a").format(ts);
          System.out.println("time is " + ts);  
      }
  }
  </code></pre>
