Calendar Toggle AM/PM is broken

[ZacharyRLewis]

The toggleAMPM function calls updateTime without a time, so toggling between AM/PM throws the following error: Cannot read property 'hour' of undefined

Uncaught TypeError: Cannot read property 'hour' of undefined

this.updateTime(event);

I've tested, and this happens in versions 1.4.0, 1.5.2, 1.5.3, and even in the latest 1.6.0 release candidate.
