DiadkoShmek opened a new issue, #55394:
URL: https://github.com/apache/arrow/issues/55394
### Describe the bug
`negate_checked` silently wraps for the minimum valid duration value instead
of returning the documented overflow error. Reproduced with PyArrow 26.0.1 on
Linux x86-64:
```python
import pyarrow as pa
import pyarrow.compute as pc
minimum = -(1 << 63)
a = pa.array([minimum], type=pa.duration("ns"))
assert a[0].is_valid and a.null_count == 0
pc.negate_checked(a).cast(pa.int64()).to_pylist()
# [-9223372036854775808]
pc.negate_checked(pa.array([minimum], type=pa.int64()))
# ArrowInvalid: overflow
```
The same duration result occurs for `s`, `ms`, `us` and `ns`, including
valid scalars. Negating this value requires `9223372036854775808`, which the
duration's signed int64 storage cannot represent. It should raise an overflow
error; the ordinary unchecked `negate` wrapping behavior can remain unchanged.
Current main `690ed5665832e10358618614e506c590f2a61bf9`,
`cpp/src/arrow/compute/kernels/scalar_arithmetic.cc:1815-1820`, registers
duration kernels under `negate_checked` with
`ArithmeticExec<ScalarUnaryNotNull, Negate>`. The existing `NegateChecked`
helper is used for the other checked numeric negations.
