There is also CalendarIntervalType.  Is that what you are looking for?

Hi, I don't see any mention of a time type in the documentation (there is DateType and TimestampType, but not TimeType), and have been unable to find any documentation about whether this will be supported in the future. Does anyone know if this is currently supported or will be supported in the future?
