The two primary aspects of time setup are typically setting the time zone and setting the Network Time Protocol (NTP) server. The systemsetup command can be used to set both of these date and time options for Mac OS X computers. To see a listing of the available time zones in Mac OS X use the systemsetup with the -listtimezones option as follows:
systemsetup -listtimezones

Apple continues to develop and support macOS Server, which includes Open Directory, Profile Manager, and Xsan management. The most popular server features—Caching Server, File Sharing Server, and Time Machine Server are bundled with every installation of macOS High Sierra and later, so that even more customers have access to these essential services at no extra cost. By Time Synchronisation This tool is used to query a server with the network time protocol (NTP) service enabled it will return all the data usually passed to a client. This tool is used for. For server addresses, this command mobilizes a persistent client mode association with the specified remote server or local radio clock. In this mode the local clock can synchronized to the remote server, but the remote server can never be synchronized to the local clock. NTP peer mode has been removed for security reasons.

It is often easiest to simply paste the time zone into the command. So to set the time zone to Detroit for example, you would use the following command:
systemsetup -settimezone America/Detroit

Once the time zone has been set then you’ll need to setup the time server. Prior to setting an NTP server, first enable network time. This can be done by using the systemsetup command with the -setusingnetworktime option followed by on or off (according to whether it is being enabled or disabled, in this case enabled):
  • NTP Clock Sync then updates the date and time using the Network Time Server set in System Preferences. NTP Clock Sync is very useful for Macs that are using Active Directory (AD) for authentication. Since AD requires the date and time to be very close to the AD Servers date and time, any variation in the Macs clock can result in login problems.
  • MacOS Server brings even more power to your business, home office, or school. Designed to work with macOS and iOS, macOS Server makes it easy to configure Mac and iOS devices. It’s also remarkably simple to install, set up, and manage. Add macOS Server to your Mac from the Mac App Store for just $19.99.
Finally, set the actual NTP server. To set an NTP server use the -setnetworktimeserver option with systemsetup, followed by the name or IP address of the server. For example, to set the NTP server to ntp.krypted.com you would use the following command:

Finally, you need to verify the time is correct. To do so you can use the date command. Or you can use the systemsetup command with the -gettime option as follows:
If you’re not using an NTP server then you’ll need to use the -settime and -setdate options to set the time and date respectively with systemsetup. Each is separated by a : character. The date is set using mm:dd:yy, so to set the date to July 12th, 2009 use the following command:

To then set the time to 11:30pm with no seconds use the following command:
