/** This test exists to check logic on a utility method.
* The tagging rule for resource expiry uses a variable nubmer of days.
* However, JodaTime date arithmetic for DAYS uses calendar days. It does NOT
* treat a day as 24 hours in this case (HOUR arithmetic, however, does).
* Therefore, a termination policy of 4 days (96 hours) will actually occur in
* 95 hours if the resource is tagged with that rule within 4 days of the DST
* cutover.
*
* We experienced test case failures around the 2014 spring DST cutover that
* prevented us from getting green builds. So, the assertion logic was loosened
* to check that we were within a day of the expected date. For the test case,
* all but 4 days of the year this problem never shows up. To verify that our
* fix was correct, this test case explicitly sets the date. The other tests
* that use a DateTime of "DateTime.now()" are not true unit tests, because the
* test does not isolate the date. They are actually a partial integration test,
* as they leave the date up to the system where the test executes.
*
* We have to mock the call to MonkeyCalendar.now() because the constructor
* for that class uses Calendar.getInstance() internally.
*
