Paul Bergeron updated HIVE-3454:
--------------------------------

    Labels: newbie newdev patch  (was: )
    Status: Patch Available  (was: Open)

Using java.sql.Date instead of java.util.Date because java.sql.Date implements 
a timezone agnostic method of representing timestamps (always UTC, which is 
what a unix epoch timestamp is defined as)
                
> Problem with CAST(BIGINT as TIMESTAMP)

> 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.
