  "message": "[test](be) Complete TimeStampNsValue interface coverage\n\n### What problem does this PR solve?\n\nIssue Number: None\n\nRelated PR: None\n\nProblem Summary: TimeStampNsValue exposed unused arithmetic, date-difference, and seeded-hash helpers while several retained calendar, difference, formatting, interval, and truncation interfaces lacked direct unit-test coverage. Remove the unused public interfaces, keep the internally required time-difference helper private, and add boundary-focused tests for every retained behavior.\n\n### Release note\n\nNone\n\n### Check List (For Author)\n\n- Test: Unit Test\n    - ./run-be-ut.sh --run --filter\u003d\u0027DataTypeTimeStampNsTest.*\u0027 -j 8\n    - build-support/check-build-hygiene.sh\n    - build-support/check-format.sh with clang-format 16\n    - build-support/run-clang-tidy.sh --build-dir be/ut_build_ASAN with clang-tidy 16\n- Behavior changed: No; unused C++ interfaces were removed and retained behavior was not changed\n- Does this need documentation: No\n",
