----------------------------------

             Summary: Date casting to string is giving wrong value
                 Key: SPARK-31887
                 URL: https://issues.apache.org/jira/browse/SPARK-31887
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 2.4.5
         Environment: The spark is running on cluster mode with Mesos.

 

Mesos agents are dockerised running on Ubuntu 18.

 

Timezone setting of docker instance: UTC

Timezone of server hosting docker: America/New_York

Timezone of driver machine: America/New_York
            Reporter: Amit Gupta


The code converts the string to date and then write it in csv.
{code:java}
val x = Seq(("2020-02-19", "2020-02-19 05:11:00")).toDF("a", "b").select('a.cast("date"), 'b.cast("timestamp"))

x.show()

+----------+-------------------+
|         a|                  b|
+----------+-------------------+
|2020-02-19|2020-02-19 05:11:00|
+----------+-------------------+

x.write.mode("overwrite").option("header", true).csv("/tmp/test1.csv")
{code}
 

The date written in CSV file is different:
{code:java}
> snakebite cat "/tmp/test1.csv/*.csv"
a,b
2020-02-18,2020-02-19T05:11:00.000Z{code}
