title: 24 hour time format (so no AM to PM) for fullCalendar
body: <p>I'm trying to display the 24 hour time format in fullCalendar, I'm trying to use these instructions: <a href="http://arshaw.com/fullcalendar/docs/text/timeFormat/" rel="noreferrer">http://arshaw.com/fullcalendar/docs/text/timeFormat/</a></p>
  
  <p>So I've added </p>
  
  <pre class="lang-js prettyprint-override"><code>timeFormat: {
      agenda: 'H(:mm)' //h:mm{ - h:mm}'
  },
  </code></pre>
  
  <p>to json.php :</p>
  
  <pre class="lang-js prettyprint-override"><code>$(document).ready(function() {
      $('#calendar').fullCalendar({
          header: {
              left: 'prev,next today',
              center: 'title',
              right: 'month,agendaWeek,agendaDay'
          },
          editable: true,
          allDayDefault: false,
          events: "core/displays/calendar/json-events.php", 
          defaultView: 'agendaDay',
          timeFormat: {
              agenda: 'H(:mm)' //h:mm{ - h:mm}'
          },
          eventDrop: function(event, delta) {
              alert(event.title + ' was moved ' + delta + ' days\n' + '(should probably update your database)');
          },
          eventClick: function(calEvent, jsEvent, view) {     
              window.location = "details_view.php?id=" + calEvent.id;
          },
          loading: function(bool) {
              if (bool)
                  $('#loading').show();
              else
                  $('#loading').hide();
          }
      });
  });
  </code></pre>
  
  <p>but that didn't work, so I've added to fullCalendar.js</p>
  
  <pre class="lang-js prettyprint-override"><code>// time formats
  titleFormat: {
      month: 'MMMM yyyy',
      week: "MMM d[ yyyy]{ '&amp;#8212;'[ MMM] d yyyy}",
      day: 'dddd, MMM d, yyyy'
  },
  columnFormat: {
      month: 'ddd',
      week: 'ddd M/d',
      day: 'dddd M/d'
  },
  axisFormat: 'H(:mm)', //,'h(:mm)tt',
  timeFormat: {
      agenda: 'H(:mm)' //h:mm{ - h:mm}'
  },
  // locale
  </code></pre>
  
  <p>but that didn't work either, what am I doing wrong?</p>
