Latitude and longitude are Western concepts; concepts which the Polynesians did not actually use as such. However, they were navigators, so some of their navigational concepts and practices would obviously map to the concepts of other navigators due to a shared domain. Similarly, they obviously had some concept of time. You could probably map their concepts onto hours and minutes, but if someone said they didn't have hours and minutes, they'd be right. The existence of the mapping doesn't invalidate that.
