   We don't have a data type for date time as of now, so we need to use other data type (`STRING`, `INT` or `LONG`) to represent the values. We process date time fields the same way as dimensions and metrics, so the ordering must be aligned with the data type. Ordering date time field differently will cause wrong result.
