Sean,
  You may be over engineering your solution.   Most modern motion
controlled floodlights have a built in photo sensor that detects
whether it is daytime or nighttime.

Additionally, sunrise and sunset change everyday.   With a timer,
you'll need to adjust it regularly to correspond with the changes to
day and night.  Using one with a built in photo sensor will alleviate
this and other problems associated with using a timer.
