Starting a fluid sim NOT at frame 0


Can anybody tell me how I start a fluid sim at a frame other than frame zero. Even though I have Time: Start set to 10, Blender 2.66 (MAC) still starts to calculate from frame 0.

I thought that using 10 would mean the sim would start calculating 10 seconds in (Frame 250 @ 25fps). No matter what I set this Start Time to it calculates from frame 0 wasting a lot of time calculating stuff I don’t need.

I also have an Ocean sim running too (from frame 0). Has that anything to do with it?

I am trying to drop an object into an ocean and get some splashes. But don’t need the splashes until several seconds into the animation.
