I wasn't quite sure about all the settings, I jsut wanted to make the night shorter than vanilla so I changed the default in the .json file to day length 45 and night length 15,   but it does not seem different. Am I missing a step?

Looking at the age of most posts here, wondering if this plugin is even supported anymore?

i guess it works, set to 55 min of day and 5 min of night and timed it. Works great.
