Arijit Banerjee commented on HIVE-3454:
---------------------------------------
Query : select cast(unix_timestamp()*1.0 as timestamp) , cast(unix_timestamp()
as timestamp) from mycrime limit 1;
Output(After patching with HIVE-3454.patch) - both returns same and correct
timestamps.

> Ran into an issue while working with timestamp conversion.
> CAST(unix_timestamp() as TIMESTAMP) should create a timestamp for the current
> time from the BIGINT returned by unix_timestamp()
> Instead, however, a 1970-01-16 timestamp is returned.
