After trying we discarded snakemake for the same reason. The time
stamps are whole seconds. Cluster builds over NFS get confused and
unreliable. At least in our experience. I think the problem is that
the granularity of a second is too low, combined with the NFS/time
synchronization of machines.

Anyway, time stamps also really don't tell you whether a file is
complete or not.
