Oops, typo.. It should be UIT or ITU and not IUT and I forgot the cavet. 
In general any exotic scale would have to be either created from scratch 
or calculated from the available TAI based scales as none are 
transmitted. Many web pages of course will give nice clock animations. I 
recommend tvb's.
