ChronyControl

MacOS 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 may be at wild variance with true time. The chrony software addresses the issues associated with ntpd. ChronyControl provides a straight forward means of installing and monitoring the daemon. ChronyControl will install the chrony software and associated files on your Macintosh. 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.
