[jira] [Comment Edited] (SPARK-27546) Should repalce DateTimeUtils#defaultTimeZoneuse with sessionLocalTimeZone

    [ https://issues.apache.org/jira/browse/SPARK-27546?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16823801#comment-16823801 ]

see an example like this:

 
{code:java}
// config spark session with "spark.sql.session.timeZone", "UTC"
val df = mockDF
// TimeZone.setDefault(TimeZone.getTimeZone("UTC"))
val date = new Date(1356998400000L) // 2013-01-01 (UTC)
val ts = df.select(lit(date).cast(TimestampType).cast(DateType)).head().getDate(0).getTime

{code}
The ts I got is: 1356969600000 (12/31/2012 UTC)

 

When I set "TimeZone.setDefault(TimeZone.getTimeZone("UTC"))", the ts is same with 1356998400000.
