ChronyControl 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.

Version: 1.1.2
New version, no development build anymore. Works great.

Version: 1.1.1
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.
