The docs https://www.man7.org/linux/man-pages/man5/systemd.timer.5.html say this Note that this setting is primarily a power saving option that allows coalescing CPU wake-ups. It should not be confused with RandomizedDelaySec= (see below) which adds a random value to the time the timer shall elapse next and whose purpose is the opposite: to stretch elapsing of timer events over a longer period to reduce workload spikes. For further details and explanations and how both settings play together, see below. So if you have 5 timers that expire about the same time this allows them to all run at the sane time thus saving power. Barry
