When we render a DATE-TIME, we are using "FORM #2: DATE WITH UTC TIME" as
defined by rfc2445, which means a date in UTC timezone. The test was setting
dates using machine timezone, and later comparing the UTC rendering with those
machine's timezone dates. Change the test to simply set UTC dates on documents.
