Wenchen Fan 417ad92502 [SPARK-23715][SQL] the input of to/from_utc_timestamp can not have timezone ... ## What changes were proposed in this pull request? `from_utc_timestamp` assumes its input is in UTC timezone and shifts it to the specified timezone. When the timestamp contains timezone(e.g. `2018-03-13T06:18:23+00:00`), Spark breaks the semantic and respect the timezone in the string. This is not what user expects and the result is different from Hive/Impala. `to_utc_timestamp` has the same problem. More details please refer to the JIRA ticket. This PR fixes this by returning null if the input timestamp contains timezone. ## How was this patch tested? new tests Author: Wenchen Fan <wenchen@databricks.com> Closes #21169 from cloud-fan/from_utc_timezone.		2018-05-03 19:27:01 +08:00
