Jason Dere commented on HIVE-3454:
----------------------------------
I guess the only possible issue here might be for expressions that get
evaluated during compilation as opposed to during the tasks, something like
cast(0 as timestamp) which would get evaluated by constant folding. Not sure if
there is any other possible work/tasks that happen locally in-process.

> 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.
