Inconclusive test glance.tests.functional.test_bin_glance_cache_manage:TestBinGlanceCacheManage.test_cache_index when local timezone is not UTC

[Brian Waldon]

Running glance.tests.functional.test_bin_glance_cache_manage:TestBinGlanceCacheManage.test_cache_index on a machine who's timezone is not UTC can cause a false negative. For example, my timezone is set to PST, so for the last 8 hours of the day this test fails. The assertion in the test looks for the local date in the output of 'glance-cache-manage list-cached':

My local date happens to be '2013-02-25', which is not the '2013-02-26' found in the command's output.
