Time and SPD do not work together. Get the cleats for the pedal system you use. The adjustability with Time pedals lie with the cleats. There is no adjustability on the pedal bodies themselves. I wanna say the release angles are 13* and 17* based on which foot you mount the cleats.

I've used SPD pedals briefly in the 90s but have since used Time. The cleats have a smaller profile and simpler design that clears mud and dirt easier.
