Here is one potential API
```rust
let file = File::open("data.parquet").unwrap();
let reader = ParquetRecordBatchReaderBuilder::try_new(file)?
// specify column "time" should be UTC
// will error if this type can not be read from parquet
.with_column_type("time", DateTime::Timestamp(Nanoseconds, Some("UTC"))
println!("Converted arrow schema is: {}", builder.schema());
```
I am not quite sure how to handle identifying nested types with a single
column name
Like if the parquet file has
```json
{
"my_object": {
"time": "12-01-02"
}
}
```
maybe we would refer to the `time` field like `"my_object.time"`?
