> Provide partial support for the interval year-month/interval day-time types
> in Hive. Intervals will be usable in expressions/predicates/joins:
> {noformat}
> select birthdate + interval '30-0' year to month as thirtieth_birthday
> from table
> where (current_timestamp - ts1 < interval '3 0:0:0' day to second)
> {noformat}
> This stops short of adding making the interval types usable as a storable
> column type.
