In Super Mario World, if Yoshi eats a power-up at the precise time that the level’s timer reaches 0, Mario will begin his death animation, but then cancel it through the acquisition of the power-up, bringing him back to life. The level’s timer will remain at 0; meaning that there is no longer a time limit. A side effect of the glitch is that the level’s music stops playing, meaning that although Mario is now free to explore the level, it will happen in complete silence.
