Have a look at figure 4
http://www.mso.anu.edu.au/~charley/p...neweaver04.pdf
It shows that SR
with a scale factor will produce time dilation exactly as predicted by GR using a FLRW metric.
SR using the Lorentz transformation without the scale factor produces divergent results. Only at very small redshifts can the Lorentz transformation be used to calculate time dilation.
How the FLRW metric works for time dilation and why Lorentz transformation fails unless scaled can be found in the Appendix.
