Jman.. you have to remember that any question about diet and exercise has to be answered within the context of your goals. There is no perfect answer... in spite of the fact that people love responding as if there is, when they know absolutely nothing about WHY you are working out and what you hope to achieve.
If you are lifting to gain size and have your diet and everything else in order... then its most important to lift during that time of the day that you have the most energy and you are going to get the best lift and can exert yourself the most. for me, 1pm or so is best. often, i just go when i feel like it, whether its 1 or 3 or 5 or whatever. If you are not doing it for size and trying to burn fat as a first concern and have your diet in order... then usually, the earlier in the day, the better.
unless you have some real goals that you are focused on, it doesn't really matter when you work out... it only matters that you do.
