------------------------------------
Summary: 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.
