---------------------------------------------------------------
I can close existing PR and open another to match both (without supporting
{{dateFormat}} for writing) for simplicity.
Actually, initial proposal was just for CSV to match JSON and to add a support
{{dateFormat}} for writing as well but it become kind of bigger.
Just FYI, I had a talk about him, here

I don't have strong preference. I will follow your decision!

> CSV data source does not write date and timestamp correctly

> Key: SPARK-16216
> URL: https://issues.apache.org/jira/browse/SPARK-16216
> 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.
