Determining a rock age using volcanic ash layer?

I wanted to know if volcanic ash deposits found in the geologic record are most useful in correlating the age of rock layers if the volcanic ash was distributed over a large area during a short period of time or large area during a long period of timeI was thinking over a long period of time because it helps more with determining a rocks age.
