Bug 196894 BIRT Cross tab, Cube - Time dimension enhancements
There were a couple of time dimension related enhancments planned post BIRT 2.2. This entry is to track those. This enhancments also includes - supporting additional predefined data time formats, that could make it easier to define data time dimension and use it in data items.
