Numerically solving InterpolatingFunction

I would like to find out if there is a way to numerically solve (probably NSolve) an InterpolatingFunction which is the result of doing NDSolve. For example, x[t] is given by NDSolve as an InterpolatingFunction and I want to solve x[t] == 0 for t. twlee at lems.brown.edu
