Chrony network timekeeping.

Overview

ChronyControl provides a straightforward means fo installing and monitoring chrony, which has now been ported to OS X. The standard installation of OS X includes ntpd, probably the most widely used software for keeping a computer clock synchronised with other computers/clocks on the Internet. However, unless the Mac is online for extended periods of time, ntpd can be very slow to synchronise with other clocks, and the system time can be at wild variance with true time. The chrony software addresses the issues associated with ntpd. This is fully explained in the FAQ.

Files installed by ChronyControl:

  • ChronyControl will install the chrony software and associated files on your Macintosh
  • chronyd - /usr/local/bin
  • chronyc - /usr/local/bin
  • chronylogrotate.sh - /usr/local/bin
  • chrony.conf - /etc/chrony.d/chrony.conf
  • launchd plist - /Library/LaunchDaemons/org.tuxfamily.chronyd.plist
  • launchd plist - /Library/LaunchDaemons/org.tuxfamily.chronyc.plist
  • privileged helper - /Library/PrivilegedHelperTools/net.whatroute.chronycontrol

After installation you can also monitor and configure the chrony software from the command line, as you would on any other Unix system. The commands are documented at the chrony website.

Note: While the software is classified as free, it is actually donationware. Please consider making a donation to help support development.

Installed on 10.11.3, and even though it still has a development build sitting at the heart of it, it seems to work fine. Since I have a lot of sleep time, shutdowns & reboots on my system, chronyd is probably a better solution than ntpd. My question is only this: One day, when there's a stable release, the CLI version including daemons will surely be available via homebrew, so I'd like to know if it's safe to just keep the ChronyControl application package in /Applications & its privileged helper, the rotate .sh (and maybe the configuration file) in place, and delete the rest, and then re-install binaries, daemons etc. with homebrew.

Sure - ChronyControl is really intended for folk who think Homebrew is something you drink.

It does however give you the ability to configure and start/stop the daemon without using sudo in the Terminal or having to build/tailor launchd scripts

If chrony is installed manually (i.e from source, homebrew, macports etc) ChronyControl can still monitor the daemon if the appropriate file paths are set in Preferences.

When chrony-2.3 is released I'll update ChronyControl again. That should be pretty soon. The default install paths used by ChronyControl are the same as those used when building chrony from source so you can easily reinstall just the chronyc and chronyd from source.

Hope that helps
