What? Do you actually have a citation for a tired light model that predicts time dilation? It certainly is not mentioned in Zwicky's 1929 paper. I'm also pretty sure that compton scattering (which produces a frequency shift) does not produce time dilation, though I'd be happy to be proved wrong on that point.
