Exterior Light Timer

I want to control my head (off the lights on the front porch and the house) side lights (apply) lights, and Back Porch (recessed lights) on a timer. They are all fluorescent bulbs. Is it possible that I can do when some of them are on the triple-pole switch, where all switches are outside lights? I know I can make the cell, but it seems more complicated and I have no idea how to install this.

I purchased and installed a switch from Home Depot that has a timer, and even automatically adjust the daylight saving time. Turn the lights on at dusk and dawn. This is a switch inside to control my lights applied to the outside. I am pretty sure he can be plugged into a three-way. It was as simple as installing a switch. A bit difficult to program, but I did. Simply push the switch to manually turn on or turn off the lights. Intermatic he does.

The easiest would be to set up motion sensors that automatically turn on and will turn, if the light goes off and on again, they also come with the dusk on timers, so many choices

You might get lucky and see if they are all on the same breaker and then just a box next to the timer configuration dialog. otherwise, you must find the first place the wire starts to feed others and save your timer there.
