Easy.  Use the calculated time of sunset and subtract an hour or hour or
so and check for that.  You can make your offset by just seeing what
time you want the light on and compare that to the calculated sunset. 
They you can even set an item like TIME-DUSK to that time and use it to
program anything.  I do something like that and also have ECS check the
light sensor (analog input with a photoresistor) and then set another
state holder "T\F Dark" and then turn lights on via it.  That takes into
account very dark stormy days, heavy fog days, and even eclipses, solar
burnouts, and those very rare days that the sun doesn't rise!!!!

IF     TIME        is now   TIME-DUSK
OR     T/F DARK    is now   TRUE
THEN   LIGHT       set      ON
