Summary

As always, we've covered a lot of ground and had a bit of fun in the process. We started by discussing why accurate timekeeping is so important and then did a quick overview of the various implementations of timekeeping software. We then took a detailed look at chrony and systemd-timesyncd. We wrapped up with a quick look at PTP.

In the next chapter, we'll look at systemd's relationship with boot managers and bootloaders. I'll see you there.
