Reynold Xin commented on SPARK-18350:
-------------------------------------

If it is session specific, I don't think we need an API. Just use the existing 
SQL conf.

Also no need to introduce a new data type. That's a much bigger scope.


> Support session local timezone

> 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.
