That is not what user "stusviews" said above (if I understood his post correctly).

Ok, how about this? My goal is to have the outside lights turn on from sunset until 6:30pm. That is until sunset becomes after 6:30 pm then the lights just shouldn't turn on. In other words the lights would turn on and be on for a less and less amount of time each day until sunset becomes later than 6:30pm. Variable Sunset is an integer and is set to 0 at sunrise (see program 3). --------------------------------------- PROGRAM 1 (Sunset): If From Sunset To Sunset + 2 hours (same day) Then $Sunset += 1 Run Program 'LightsOn' (If) Else $Sunset = 0 --------------------------------------- --------------------------------------- PROGRAM 2 (LightsOn): If From Sunset To 6:30:00PM (same day) And $Sunset is 1 Then Set 'OutsideLights' On Else Set 'OutsideLights' Off --------------------------------------- --------------------------------------- PROGRAM 3 (SunsetReset): If From 6:30:00PM To Sunrise (next day) Then $Sunset += 1 Else $Sunset = 0 ---------------------------------------

Ok then, what's the difference between these two? From Sunset For 2 hours Then turn light on Else turn light off -----and this one----- From Sunset To Sunset + 2 hours Then turn light on Else turn light off Anything?

Didn't know how exactly to search for this subject. I currently have a program to run from sunset to 6:30pm (same day) everyday. At sunset some lights are turned on and at 6:30pm the lights are turned off. This time of year it is no problem as sunset is at about 5:00pm. What happens later in the year (and especially after the time change) when sunset is after 6:30pm? Will the program run backwards? Say sunset is at 7:00pm. Will the lights be turned off at 6:30pm (they would already be off) and then at sunset (at 7:00pm) they would be turned on?
