This is simply not true. SAS has all sorts of capabilities for doing arithmetic with dates, times and datetimes, including some very useful formats and functions for computing intervals. The original poster asked for suggestions of things that were difficult/impossible to do in SAS or SPSS with the goal of getting SAS/SPSS users to consider R. The only thing he would accomplish by making the above claim to that audience is a loss of credibility.
