What Tim mean is that, by default, SGE will schedule your job when sufficient resources are effectively available, rather that trying to predict when that will happen.
That said, you /can/ specify both a minimal starting time (with -a) and a deadline (with -dl) creating a "window" during which SGE will try to run your job but, in general, it's easier and more reliable to let the gridengine pick the time.
If your objective is to have your job run only when few others are trying to use the resources, you can also lower its priority (with -p) so that it will only execute your job when there isn't anything "better" to run.
