I've only just recently started using blender (this is 2.78a) and am amazed at how much can be accomplished with it. I have been playing around with the fluid simulation, but all the different settings are a bit of a mystery, so I have a few questions, but I will start here with just one, and post others separately.
In trying to get multiple fluids to interact, I found that unfortunately, it is not possible, and the best one can get is: How to bake multiple fluid simulations in one scene?. However, in that answer, William Hopper mentions that to delay the start of the sim, one must change the "offset", but isn't that what "Time: Start" is for? What does each of these settings do?
My natural guess form the tooltip "Offset when reading baked cache" is so that one can have multiple baked domains in the same path, without having to do that workaround mentioned in the answer linked above.
