Jesus Camacho Rodriguez commented on HIVE-14751:
------------------------------------------------

Patch contains support for floor syntax.

In addition, it contains a fix for date floor UDFs concerning timezone that is exposed in
the tests. Default timezone for the tests is PST, while UDFs logic works in UTC.
