This "age" cheat on bathtubs?

I was messing around with the "boolprop testingcheatsenabled" cheat when I found this cheat interaction after shift+left clicking on a bathtub and shower called "Age". I tried applying it but I found no difference before and after using this interaction. Anybody knows what's the actual function of this cheat interaction?
