Thanks holli,

I can't see how I can avoid arithmetic, but as I said, this is the second full-blown attempt at refactoring this in the last six months, so I could be blinded.

Somehow I need to know if the on/off time is between two times. So if I am in vegetative "season", my grow lights would be on for 18 hours a day, so I'd have to figure out what time of day it is, and check if we're within that range or not.

Am I missing something?
