Explicit support for randomizing timers across multiple hosts is a really nice features of the timers provided by systemd:
"AccuracySec=" in *.timer files lets you specify the amount of slack systemd has in firing timers. To quote the documentation "Within this time window, the expiry time will be placed at a host-specific, randomized but stable position that is synchronized between all local timer units."
You may still want to randomize timers locally on a host too, but the above makes automated deployment of timers that affects network services very convenient.
