Set the network Time Server: sudo systemsetup -setnetworktimeserver Set the time zone : sudo systemsetup -settimezone "Europe/Paris"Įnable Network Time: sudo systemsetup -setusingnetworktime on Stop ntpd sudo launchctl unload /System/Library/LaunchDaemons/ If you need to find out your timezone : sudo systemsetup -listtimezones Reload the ntpd service : sudo launchctl load /System/Library/LaunchDaemons/ Restrict -6 default kod nomodify notrap nopeer To : restrict default kod nomodify notrap nopeer Restrict -6 default kod nomodify notrap nopeer noquery & :Ĭhange from : restrict default kod nomodify notrap nopeer noquery iburst option will cause ntpd to synchronize right upon startup and not waiting too long. Two ntp Servers as source ( + other internal Server) /etc/ntp.confĮdit the file /etc/ntp.conf and add iburst at the end of the line of the ‘primary’ ntp server. Server Setup Unload the ntpd service : sudo launchctl unload /System/Library/LaunchDaemons/

We’ll do as follow on the Clients : Server hostname We’ll do as follow on the Servers : Server hostname I’ll consider you’ve setup the Time in System Preferences. On the Servers you want to deliver Network Time to your Computers, 2 would be a good choice.

Make sure your DNS are Ok and if needed Add Aliases records Setting up Time servers on Os X (servers) for the Os X clients of your network.
