It's actually two timers, in my experience.

The first is the one most people encounter, where you just need to shuffle a few feet to continue fishing.

The second will lock you out of fishing in that fishing hole entirely, until you fish somewhere else. After at least one cast in a different hole, though, you can resume fishing where you were before.
