I recognize this could add complexity, but it would be very very cool if the option to distinguish between night and day could be added. 

Maybe a config can be scheduled one of two ways: by day cycle or by day of the wipe. You would never do both.

For instance, if you wanted night gather to change, you'd configure the config to be replaced at night and then at day, but not on the 15th day of the month or they'd conflict.

This would give admins the ability to make night more dynamic.
