Reynold Xin updated SPARK-18350:
--------------------------------
    Description: 
As of Spark 2.1, Spark SQL assumes the machine timezone for datetime 
manipulation, which is bad if users are not in the same timezones as the 
machines, or if different users have different timezones.

We should introduce a session local timezone setting that is used for execution.

An explicit non-goal is locale handling.
