Problem

The default timezone for Wikipedia is UTC in the 24-hour format. The Timeline currently uses the browser timezone as an offset and displays the time in the 24-hour format.

In the future, if/when we have OAuth we can pull from the time zone offset user preference.

Acceptance criteria

• The timestamps in the Timeline should display in UTC
• The timestamps in the Timeline should display as 24-hour (e.g. 14:00 instead of 2:00pm)
• The date needs to use UTC date as well
