This has most likely been asked before plenty of times, I did search but couldn't find any previous posts although in hindsight maybe I didn't word my search term very well.
Anyway, I'm trying to find a mod that slows down the day and night time cycle so there's more daylight and more night time; something a little more realistic than only 10 minutes of daylight and 10 minutes of darkness.
Mods I have found are either broken or aren't supported by 1.8.9. I have Forge 126.96.36.1999.
I know there aren't any commands to do this (only /gamerule doDayLightCycle false).
