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

Seems this issue has not been fixe completely. I still see
{code}
hive> SELECT CAST(CAST(-1200.0 AS TIMESTAMP) AS DOUBLE);
OK
-1200.0
Time taken: 0.047 seconds, Fetched: 1 row(s)
hive> SELECT CAST(CAST(-1200 AS TIMESTAMP) AS INT);
OK
-2
Time taken: 0.044 seconds, Fetched: 1 row(s)
{code}

> 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.
