Dongjoon Hyun commented on SPARK-27546:
---------------------------------------
Hi, [~Aron.tao]. The given example looks irrelevant to Apache Spark because
it's Java `Date`'s behavior before arriving Apache Spark.
{code}
jshell> new Date(1356998400000L)
$1 ==> Mon Dec 31 16:00:00 PST 2012
jshell> TimeZone.setDefault(TimeZone.getTimeZone("UTC"))
jshell> new Date(1356998400000L)
$3 ==> Tue Jan 01 00:00:00 UTC 2013
{code}
Whatever you do in Apache Spark, `new Date` give you the value from JVM's
default Timezone, doesn't it?
> Should repalce DateTimeUtils#defaultTimeZoneuse with sessionLocalTimeZone
