On the GP21 board I used it was more like 10ns+. I don't know if that's typical, but it wasn't a even particularly cheapo crystal as the original one was faulty and I had to replace it. The official acam board might be better, but the data sheet specifically talks about the 32K osc having a lot of jitter. One of the problems of the data sheet is that it is really tailored for those using it as a flow converter - some of the text does not even make sense otherwise. That was one of the reasons I was planning to test it more as a TDC, but just getting back to doing that now.
