Sorry for a bump but I like to help people. :)
Here this is how I got mine to work in TGEA, There is probably no difference from TGE and TGEA rising and setting anyways here you go.
Go to inspector and to the fxsunlight



Pretty much copy everything except the AzimuthTime and ElevationTime, make them 1-9000 the lower, the higher it will rise and fall.
Mine is still glitchy but it's the best I have. :)
Let me know if it works.
