The check that tells the two apart
fail→pass·tests/test_incremental_processor.py::test_normalizes_timestamp_units[1770000000000-1770000000.0]
Check file tests/test_incremental_processor.py, taken without changes from the fix and copied onto the older code, so the exact same check runs against both versions.
