Wenchen Fan 0ba98c04c7 [SPARK-8753][SQL] Create an IntervalType data type ... We need a new data type to represent time intervals. Because we can't determine how many days in a month, so we need 2 values for interval: a int `months`, a long `microseconds`. The interval literal syntax looks like: `interval 3 years -4 month 4 weeks 3 second` Because we use number of 100ns as value of `TimestampType`, so it may not makes sense to support nano second unit.
