[~rdblue] Thank you for your review. I attached changed patch. And if timezone is constant
(e.g. 'PST'), it confirms at initialize-method.

> Using an unknown time zone with the {{from_utc_timestamp}} or {{to_utc_timetamp}} methods
returns the time un-adjusted instead of throwing an error:
> {code}
> hive> select from_utc_timestamp('2015-04-11 12:24:34.535', 'panda');
> OK
> 2015-04-11 12:24:34.535
> {code}
> This should be an error because users may attempt to adjust to valid but unknown zones,
like PDT or MDT. This would produce incorrect results with no warning or error.
