This is probably a stupid question, but you are plugging the CF
lights into the yellow plugs, right?
I have a Coralife timer, but mine isn't digital, so I can't help with the programming.
Also, with mine, the nightlights (or whatever is plugged into the nighttime plugs) come on when the daytime things go off....so if the time is during when your daytime lights are off (its after 1pm here), the nightlights will probably come on. I'm not sure if its like mine or not though.
Hope that helps a little...
