Dusk does 3 things
-Increase night monster count
-Increase base monster cap
And...
-> Set min Sleep time
I have set it to 15000, bc I wanted to activate bed only after complete darkness emerges
So it wouldn't be so easy to avoid nights
But after some time I saw that I can activate bed before darkness, which means something is counted differently

vanilla bedding time is 12500

It would be also nice if after waking up sun was on a horizon, not above it, to have more time in day
It's also nice too see sunrise from horizon

EDIT: I tested it on day duration 60s and dayTicks are counted proportionally to the part of the day.
So it works, but I remember that I could access bed before darkness.
It could be related to fact I was turning off/on DoDayLightCycyle gamerule, when pregenerating chunks on AFK.
Which now I read is defaulty disabled in this mod.

Second issue is, if you change values in config file via config colder it doesnt load up into game
And from what Ive seen forge menu for config has different options than in folder
And config in forge menu works and it doesnt overrides config from folder.
What I did was, edit config timecontrol-common.toml via notepadd++ save it and then launch MC launcher and generate new world and it didnt affected forge config or how game behaves.
(But I dont care about this issue, only wanted to inform, I can now change config while ingame easily)
