Of course, deadline scheduling depends on exactly this: an application must declare a worst-case execution time along with its deadline. Knowing what the WCET should be is, of course, not a small problem; it's currently fodder for a number of academic careers, I think. Usual practice, I suspect, is to determine it empirically.

As for what happens if you blow the WCET: the deadline scheduler just freezes you out until the next scheduling period starts.
