FullCalendar not displaying time from JSON events

Try adding 'allDay': false to your json. I had the same issue, see 'allDay' documentation specifically:

Don't include quotes around your true/false. This value is not a string!

When specifying Event Objects for events or eventSources, omitting this property will make it inherit from allDayDefault, which is normally false.

However, 'allDayDefault' defaults to true?!?
