> 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.
