--------------------------------

Yeah. Thanks for pointing that out. I also notice that problem. We won't be able to override
during the session with that approach and also we could have problem if we run in the real
cluster as Brock pointed out. I'm trying a different approach.

> 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.
