Hello, Thanks for the link to the Linux Foundation blog post about ntp and Chrony. I had been using ntp for years but will now switch to Chrony as its code base is more modern, secure, and maintainable. Also hoping to just run less code, and I like the sound of Chrony's simpler implementation.
As far as I can tell, systemd-timedated does not handle network time itself. That is the responsibility of systemd-timesyncd, which is including in systemd 213 and up, but was disabled by RedHat in RHEL7 / CentOS 7 for whatever reason despite that distro shipping with systemd 219. For simplicity I do prefer systemd-timesyncd on modern Debian-based systems, however.  https://www.freedesktop.org/wiki/Software/systemd/timedated/  https://lists.freedesktop.org/archives/systemd-devel/2014-May/019537.html Cheers, On Wed, Jan 17, 2018 at 7:01 PM Patrick Goetz <pgo...@math.utexas.edu> wrote: > On newer systemd-based systems you can just use timedatectl -- I find > this does everything I need it to do.
