You do multiple plugins or use constant configuration values for them. That's why you want plugins, for putting all complex stuff in actual code that doesn't have to live with the main product.

That doesn't decentralize the clock, it gives a maximum capable interface for the few people that need to handle exceptional cases, and a minimally capable one to the people that just want to use your software as is. That is, you make the product live on two opposite values of the clock at the same time.
