tswast opened a new pull request, #48018: URL: https://github.com/apache/arrow/pull/48018
### Rationale for this change I'm working on a system that supports picosecond precision timestamps, and I'm interested in interoperability with the Arrow ecosystem. See https://github.com/apache/arrow/issues/47848 ### What changes are included in this PR? This PR only adds the new enum value TimeUnit::PICO. This enum value is unused for now, but I plan to introduce a timestamp128 type in the future which supports this unit type. ### Are these changes tested? I have updated and run the C++ test suite. ``` root@dc20d61d62a2:/github.com/apache/arrow/cpp/build# ... 100% tests passed, 0 tests failed out of 91 Label Time Summary: arrow-compute-tests = 128.41 sec*proc (15 tests) arrow-tests = 65.74 sec*proc (38 tests) arrow_acero = 120.93 sec*proc (14 tests) arrow_dataset = 103.61 sec*proc (13 tests) arrow_substrait = 0.98 sec*proc (1 test) filesystem = 1.97 sec*proc (1 test) parquet-tests = 88.40 sec*proc (10 tests) unittest = 508.07 sec*proc (91 tests) Total Test time (real) = 50.20 sec ``` ### Are there any user-facing changes? **This PR includes breaking changes to public APIs.** Adding a new enum variable did break some tests that assumed that all TimeUnit::values() are valid for use in the timestamp (64-bit) data type. -- This is an automated message from the Apache Git Service.
