AFAIK, z/OS DFSORT V1R10 is used for z/OS 1.10-1.11. z/OS DFSORT V1R12 is used for z/OS 1.12. These are the only currently supported releases of DFSORT - so you seem to use an old version of DFSort and the error mesages clearly says, you don't have latest PTF to get those options working for you.
You should also look at the mesasge of type ICE201I, to determine which level of DFSORT functions you have available.
z/OS DFSORT V1R5 is no longer supported, so the date arithmetic PTF is not available for that release. You should be using one of the supported releases - z/OS DFSORT V1R10 or z/OS DFSORT V1R12. The date arithmetic PTF is available for both of those releases.
