[TIMOB-11709] Android: String.formatTime causes app crash when date is string.

When the date is a random string rather than a function(Date()) then String.formatTime causes app crash. It just gives a null output on iOS and does not crash.

Steps to reproduce:

1. Load the below app.js 2. Test it on both iOS and Android. Expected Result: On Android, the output should be null or should throw an exception. Actual Result: The App crashes on Android.

var win = Ti.UI.createWindow({
   backgroundColor:'white'
   });
win.addEventListener('click', function() {
  
var date = "GIBBERISH";
//var date = new Date();
alert( String.formatTime(date) );

	
});

win.open();
