Looks like the EST timezone changed description.

Start with tests/test_search.py::TestTranslateSearch::test_relative_base_setting_2_en and the failure output, then inspect how the relative base setting handles EST and UTC timezone objects. Determine the compatibility change needed for the latest pytz behavior and rerun this test and the full test suite; done means the failing test passes without regressing the other reported results.
