Does CoreOS have a cluster aware job scheduler?

Ive been checking out CoreOS and I'm impressed. Before I found CoreOS I was looking at the Mesos/Marathon/Chronos stack as a "cluster kernel".

Given the following comparison:

init.d == Mesos+Marathon == CoreOS+Fleet
cron   == Mesos+Chronos  == CoreOS+?????

Im curious if CoreOS has a distributed Job Scheduler? Or do most people just use Fleet to run something else?


Fleet builds on top of Systemd and Systemd has a unit called a timer for cron like functionality. https://wiki.archlinux.org/index.php/Systemd/cron_functionality
