msalib opened a new issue #393:
URL: https://github.com/apache/arrow-rs/issues/393
**Describe the bug**
If you call `take` with an Array of type `Timestamp(Milliseconds,
Some(UTC))`, you'll get a result with type `Timestamp(Milliseconds, None)`.
**To Reproduce**
If you like I can write a test case....
**Expected behavior**
I expect kernels like `take` to return an array with the same data type as
their input.
**Additional context**
I think the problem is in `compute/kernels/take.rs`:
```
DataType::Timestamp(Second, _) => {
downcast_take!(TimestampSecondType, values, indices)
}
DataType::Timestamp(Millisecond, _) => {
downcast_take!(TimestampMillisecondType, values, indices)
}
DataType::Timestamp(Microsecond, _) => {
downcast_take!(TimestampMicrosecondType, values, indices)
}
DataType::Timestamp(Nanosecond, _) => {
downcast_take!(TimestampNanosecondType, values, indices)
}
```
Note the 4 `_`s indicating that the timezone information is being dropped
and never used in constructing `take`'s output.
