Work around brittle timestamp comparisons in tests
Feed and database tests can sometimes fail because timestamps being compared against expectations are off by one second. I'm not certain how this can be worked around for PHPUnit database tests (see issue #111), but for non-database tests, we can and should fudge the date: second precision is not required for any tests, and likely will never be.
