How to set timezone on CentOS 7

In this tutorial, we are going to show you how to set up a timezone on a Linux VPS running CentOS 7 as the operating system.

In order to set the time and date on CentOS 7 we will use the command timedatectl… It is a utility that is distributed as part of the Systemd system and service manager. The timedatectl command has the following features:

  • Overview of the current date and time
  • Change date and time
  • Setting the system time zone
  • Enabling automatic synchronization of the system clock with a remote server

First of all, let’s connect to the CentOS VPS via SSH. It is always good practice to update all system software to the latest version available. You can do this with the following command:

# yum update

After the update is complete, check the system clock settings using the timedatectl command:

# timedatectl
      Local time: Fri 2016-07-04 03:21:11 EDT
  Universal time: Fri 2016-07-04 07:21:11 UTC
        RTC time: n/a
       Time zone: America/New_York (EDT, -0400)
     NTP enabled: n/a
NTP synchronized: no
 RTC in local TZ: no
      DST active: yes
 Last DST change: DST began at
                  Sun 2016-01-11 02:59:29 EST
                  Sun 2016-01-11 04:00:10 EDT
 Next DST change: DST ends (the clock jumps one hour backwards) at
                  Sun 2016-09-04 02:59:29 EDT
                  Sun 2016-09-04 02:00:10 EST

The command output should be similar to the one above. As you can see, a lot of information is presented in the output of the timedatectl command like local time, UTC, current timezone, whether NTP is enabled or not, last DST change, next DST change, etc.

The next thing you could do is set your timezone. To get a list of available time zones you can use the following command:

# timedatectl list-timezones

The output can be great and you can use Grep to filter the results. For example, if you want to list American time zones, you can use the following command:

# timedatectl list-timezones | grep Europe
Europe/Kaliningrad
...
Europe/Moscow
...
Europe/Samara
...
Europe/Uzhgorod
...
Europe/Volgograd
...

Use the following command to set the time zone:

# timedatectl set-timezone Europe/Moscow

Here you can replace Europe / Moscow with the name of the time zone you want to set. Use the timedatectl command again to view the changes.

To set a specific date and time, you can use the following syntax:

# timedatectl set-time 'YYYY-MM-DD HH:MM:SS'

For example, to set the current date 09-09-2016 and the current time 16:20:00, use the command below:

# timedatectl set-time '2016-09-09 16:20:00'

You can find more details on how to use the timedatectl command using the -help flag:

# timedatectl --help
timedatectl [OPTIONS...] COMMAND ...

Query or change system time and date settings.

  -h --help                Show this help message
     --version             Show package version
     --no-pager            Do not pipe output into a pager
     --no-ask-password     Do not prompt for password
  -H --host=[[email protected]]HOST    Operate on remote host
  -M --machine=CONTAINER   Operate on local container
     --adjust-system-clock Adjust system clock when changing local RTC mode

Commands:
  status                   Show current time settings
  set-time TIME            Set system time
  set-timezone ZONE        Set system time zone
  list-timezones           Show known time zones
  set-local-rtc BOOL       Control whether RTC is in local time
  set-ntp BOOL             Control whether NTP is enabled
