alamb opened a new issue, #5182:
URL: https://github.com/apache/arrow-rs/issues/5182
**Describe the bug**
Timstamps like `2023-12-05T21:58:10.45ZZTOP` which are invalid (they have
trailing content after the `Z`) should error when parsing (casting from String
to Timestamp) but instead they ignore the trailing content
**To Reproduce**
This test case should pass in arrow-cast/src/cast.rs
```rust
#[test]
fn test_cast_string_to_timestamp_invalid_tz() {
// content after Z should be ignored
let bad_timestamp = "2023-12-05T21:58:10.45ZZTOP";
let array = StringArray::from(vec![Some(bad_timestamp)]);
let data_types = [
DataType::Timestamp(TimeUnit::Second, None),
DataType::Timestamp(TimeUnit::Millisecond, None),
DataType::Timestamp(TimeUnit::Microsecond, None),
DataType::Timestamp(TimeUnit::Nanosecond, None),
];
for dt in data_types {
assert_eq!(
cast(&array, &dt).unwrap_err().to_string(),
"Invalid timezone: ZZTOP"
);
}
}
```
**Expected behavior**
Test case should pass, instead it fails as the timestamp is correctly parsed
**Additional context**
