Merge branch 'save_stackmax' into 'master'
core: save stackmax by tmin_ms The high frequency ASPO data set (used by Jose) requires short time windows, shorter than 1 second. stackmax traces have therefore repeatedly been overwritten. tmin_ms as file name solves this issue in this case. Using tmin_ns made the trace names lengthy and I don't think anyone needs this (until now at least). Hence, it's a compromise. See merge request !2
