I wanted to add `AssumeTimezone` kernel benchmark like:
```
static void BenchmarkISOCalendar(benchmark::State& state) {
RegressionArgs args(state);
ExecContext* ctx = default_exec_context();
const int64_t array_size = args.size / sizeof(int64_t);
auto rand = random::RandomArrayGenerator(kSeed);
auto array =
rand.Numeric<Int64Type>(array_size, kInt64Min, kInt64Max,
args.null_proportion);
EXPECT_OK_AND_ASSIGN(auto timestamp_array,
array->View(timestamp(TimeUnit::NANO)));
for (auto _ : state) {
ABORT_NOT_OK(ISOCalendar(timestamp_array, ctx).status());
}
state.SetItemsProcessed(state.iterations() * array_size);
}
BENCHMARK(BenchmarkISOCalendar)->Apply(SetArgs);
```
And got:
```
arrow-compute-scalar-temporal-benchmark(74236,0x1049e0580) malloc: Incorrect
checksum for freed object 0x105204740: probably modified after being freed.
Corrupt value: 0x3
arrow-compute-scalar-temporal-benchmark(74236,0x1049e0580) malloc: *** set a
breakpoint in malloc_error_break to debug
```
Which I assume is due to `ISOCalendar` output being a struct array. Any
ideas how to get around it? It's not a big issue but would be nice to cover.
