<h1>Time zone</h1>
<p>
The following demo shows how to display items in local time (default), in UTC, or for a specific time zone offset. By configuring your own <code>moment</code> constructor, you can display items in the time zone that you want. All timelines have the same start and end date.

<h2>Local time</h2>
<div id="local"></div>
<h2>UTC</h2>
<div id="utc"></div>
<h2>UTC +08:00</h2>
<div id="plus8"></div>
<script type="text/javascript">
// Create a DataSet (allows two way data-binding)
var today = vis.moment(vis.moment.utc().format('YYYY-MM-DDT00:00:00.000Z'));
var start = today.clone();
var end = today.clone().add(2, 'day');
var customTime = today.clone().add(28, 'hour');
var items = new vis.DataSet([
{id: 1, content: 'item 1', start: today.clone().add(8, 'hour')},
{id: 2, content: 'item 2', start: today.clone().add(16, 'hour')},
{id: 3, content: 'item 3', start: today.clone().add(32, 'hour')}
