Fix local timezone dependency in tests.

wow great idea. For now anyway, we for sure need to make the tests more flexible with timezones. (I've looked into Kiwi and whatnot and I'm of the persuasion that if the comes-with-it test suite does the job, I use it :) Don't hold me to that, I change my mind a lot. Thanks for the help.
