The test reference data was produced with accidental interference from the system daylight saving in effect at the time. Prevent that from occurring again and correct the data. * test/lisp/calendar/lunar-tests.el (with-lunar-test): Switch to UTC and make sure daylight saving adjustment is disabled. Use normal time presentation for maintainability. * test/lisp/calendar/lunar-tests.el (lunar-test-phase): Adjust to UTC. (lunar-test-phase-list): Adjust to UTC with correct times. Enable the test by removing its :unstable mark.
