You can make the clock update more often by running pacemaker with the -a option, providing a time in seconds to wait between time movements: /usr/libexec/pacemaker -a 10 1 PPM is 1 microsecond/second, or 3.6ms/h. The units of this number is PPM, or Parts Per Million. This means that the clock is -23.64 PPM away from the time that it should be. You can see how 'off' your clock is by looking at the contents of ntp.drift - for example, my file contains the following: -23.640 It uses adjtime to adjust the clock per the content of /var/db/ntp.drift. Pacemaker is the daemon responsible for managing the time in macOS. I assume it has some cleverness to avoid stepping the clock backwards but there is no way to tell. it polls the NTP periodically (15 minutes) and uses the settimeofday() system call to set the sytem clock. Timed appears to be a simple sntp client - i.e. Timed takes no arguments, and users should not launch it manually.Īccording to Apple Developer Forums user granada29 in the post ntpd, timed and chronyd in 10.13, timed performs the following: Timed also uses TMTimeSynthesizer, something which CoreTime on iOS uses to update the clock with but I'm unaware of its history on macOS:ĭon't run the timed binary yourself, as mentioned in the man page: Timed uses the time server set in /etc/ntp.conf, which by default is server $ sudo defaults read /var/db/timed/ TMLastSystemTime You can see how 'off' your clock is by looking at the contents of /var/db/timed/, under the TMLastSystemTime dictionary in the TMTimeError key and the TMScaleFactorError key.

when the daemon is loaded at boot (RunAtLoad: true).Timed is managed by the LaunchDaemon /System/Library/LaunchDaemons/. timed is also aware of power/battery conditions. Inputs are merged inside of timed, where it calculates uncertainty to facilitate scheduling proactive time jobs. Timed maintains system clock accuracy by synchronizing the clock with reference clocks via technologies like NTP.

High Sierra uses timed, from /usr/libexec/timed, run by the system user _timed. Then run again to check if the error message is gone. Some people reported this was actually breaking the ntp synchronization. So if you get the error below when checking time: kod_init_kod_db(): Cannot open KoD db file /var/db/ntp-kod: No such file or directoryĬreate the file and change ownership to root. Out of the box, a tracking file is missing. To check and update your system time, you can call sntp directly. You can also add custom fields, including unique answers to security questions.Mojave still uses timed, but ntpdate and the helpers ntpq are removed.
