MvdV>> The FTSC is not an enforcement body
The FTSC also does not _create_ standards.
This is how it usually works:
1) Someone writes a proposal.
2) For most proposals it ends there. But sometimes the developers adopt what is proposed and implement it in their software.
3) People start using that software and it becomes current pratctise.
4) If 3) happens the FTSC documents it as a standard.
Regarding the TZUTC kludge, it was proposed in FSP-1001. FSP-1001 says "no '+'" and that is what the developers adopted. And that is what the FTSC later documented as that standard.
If you want to argue against the absence of the "+", you are barking up the wrong tree. It is not the FTSC that decided there should be no "+". It is the developers that decided that by following FSP-1001.
