FYI: this is currently how I work around the issue:
```rust
fn fix_run_end_encoded_array_data_type(run_array: RunArray<Int32Type>,
data_type: &DataType) -> RunArray<Int32Type> {
match data_type {
DataType::Timestamp(TimeUnit::Nanosecond, _) => {
let run_ends = run_array.run_ends();
assert_eq!(run_ends.offset(), 0);
assert_eq!(run_ends.len(), run_array.len());
let end_array = Int32Array::new(run_ends.inner().clone(), None);
let value_array =
as_primitive_array::<TimestampNanosecondType>(run_array.values())
.clone()
.with_data_type(data_type.clone());
RunArray::try_new(&end_array, &value_array).unwrap()
}
_ => run_array,
}
}
```
