This is consumed cpu time and not wall time. If you set this on gzip,
those might get close to 1:1, but for a process that sleeps a lot, a
cpu second may well take minutes, hours or days. This is the TIME
column in top, if you want to take a quick peek at how much time a
process consumes, compared to wall time.
