Getting UTC timestamps of iCal with Timezone using the mozilla-comm/ical.js lib
//Please note I'm also using underscore each function for the iterations
//iCal -> jsCal

//jsCal->Component
var comp = new Component(icalEvents[1]);
//Get all VTIMEZONE iCalendar components
var vtimezones = comp.getAllSubcomponents("vtimezone");
//Add all timezones in iCalendar object to TimezonService
//if they are not already registered.
_.each(vtimezones, function (vtimezone) {
if (!(ICAL.TimezoneService.has(
vtimezone.getFirstPropertyValue("tzid")))) {
ICAL.TimezoneService.register(vtimezone);
}
