Early Bedtime is a simple mod that allows modpack devs and server owners to configure how early sleeping is allowed on the server.
This mod by default allows the user to sleep 1000 ticks earlier, or about 50 seconds. You can configure this in the mod's settings.
This mod was made largely because a common feature of many shaders is exaggerated sunsets, and while this looks great, it also makes you want to sleep earlier! For example, with Hysteria shaders, it gets very dark, very quickly, but vanilla doesn't get dark enough to allow sleeping until the sun goes below the horizon.
