>             Project: Spark
>          Issue Type: Improvement
>          Components: SQL
>    Affects Versions: 2.0.0
>            Reporter: Hyukjin Kwon
>            Priority: Minor

> Currently, CSV data source write {{DateType}} and {{TimestampType}} as below:
> {code}
> +----------------+
> |            date|
> +----------------+
> |1440637200000000|
> |1414459800000000|
> |1454040000000000|
> +----------------+
> {code}
> It would be nicer if it write dates and timestamps as a formatted string just like JSON data sources.
> Also, CSV data source currently supports {{dateFormat}} option to read dates and timestamps in a custom format. It might be better if this option can be applied in writing as well.
