I used TimeOfDay and ClearNight lastest versions.

TimeOfDay config, 50min day, 10min night.

But become a night, shows always changing. How can I fix?

Please post a list of installed plugins, sounds like another plugin is conflicting. Zone Time Manager causes issues if you have it installed.

Overall the plugin isn't in a healthy state right now since the weather update.
