General relativity and accelerated decay are the keys and you do not need to invoke differEnt types of time! When time rates change locally they change for everything in that frame! When decay rates change there is no effect on time! Please tell me if you need me to explain this further.
This scheme is not as ad hoc as it seems. Spatially differnt rates of time occur automatically in a bounded space-time continuum during expansion and accelerated decay would certainly occur if fundamental constants drifted as has been observed for at least one combination. In addition helium retention in granites strongly point to accelerated decay unless the diffusion physics is found to be flawed.
