+Subject: [PATCH] Freeze format_time() tests to a specific date to fix test
+ failures
+
+Freeze the date when performing the tests for format_time() with
+a timezone specified.  Since the time object does not specify a date,
+the formatter uses the format string specific to the current date.
+As a result, if the current DST state is different than when the test
+was last updated, it failed.
+
+This fix covers only regular tests.  I have no idea how to do the same
+for doctests.
+
+Issue #988
