Enable timezone on FullCalendar
<p>I'm rebuilding an existing project in which I need to have timezone support. The events get rendered fine by a json-feed. Example data:</p>

<pre><code>[{
    "id":"1",
    "title":"Titel",
    "start":"2016-10-08T12:00:00+02:00",
    "end":"2016-10-08T12:30:00+02:00",
}]
</code></pre>

<p>As you see the event has Timezone-Data. (<code>2016-10-08T12:00:00+02:00</code>)</p>

<p>I want to use <code>eventDrop</code> to update an event, an when the user drags and drops an event, the data (eventId, start_time, end_time) is sent to the PHP, which updates the database.</p>

<p>My PHP-script should convert the received start_time &amp; end_time to UTC and write it to the database.</p>

<p>The issue is that fullcalendar doesn't pass the timezone of the event to my PHP.
I tried passing something like:</p>

<pre><code>event_start: moment(event.start).format("YYYY-MM-DD HH.mm:ssZZ"),
</code></pre>

<p>The data I get is something like:</p>

<pre><code>event_start: 2016-10-08 12.00:00+0000
</code></pre>

<p>And I expected it would be something like:</p>

<pre><code>event_start: 2016-10-11 12.00:00+0200
</code></pre>

<p>With the timezone-information I could easily convert it to UTC.</p>

<p>How can I have access to the timezone on the PHP side?</p>
