   print_row_with_datafusion get wrong result
   pickup_datetime:1970-01-15 05:57:17.520
   
   
   ```Rust
   use datafusion::error::Result;
   use datafusion::prelude::ExecutionContext;
   use std::convert::TryFrom;
   use std::fs::File;
   use std::path::Path;
   
   use parquet::file::reader::FileReader;
   use parquet::file::serialized_reader::SerializedFileReader;
   
   #[tokio::test]
   async fn print_row_with_parquet() -> Result<()> {
   	let path = Path::new("yellow_taxi_sample.parquet");
   	let row_iter = SerializedFileReader::try_from(path).unwrap().into_iter();
   
   	for row in row_iter {
   		println!("{}", row);
   	}
   	Ok(())
   }
   
   #[tokio::test]
   async fn grouped_counts() -> Result<()> {
   	let mut ctx = ExecutionContext::new();
   	ctx.register_parquet("taxi_sample", "yellow_taxi_sample.parquet")
   		.await?;
   	let df = ctx.sql("SELECT * from taxi_sample").await?;
   	df.show().await?;
   
   	Ok(())
   }
