For 24:00 military display
2) slotduration - http://fullcalendar.io/docs/agenda/slotDuration/
For config time interval display in calendar view.
3) snapduration - http://fullcalendar.io/docs/agenda/snapDuration/
The time interval that will be passed to the start date and end date of the event when the user clicks over an event.
