title: NSDate format time with start and end in hours
body: <p>Is there a way to format time so that it shows up as
  <code>19-Oct-2015 3-6 PM</code>? I know how to set day, month, year. I just need to know if it's possible to set the hours so that it shows a timeframe like 3pm-6pm or if I will just have to format the strings myself.</p>
