Mastering Time: Changing Timezone on Ubuntu

Setting or Changing the Timezone on Ubuntu

As we all know, time is an essential aspect of our lives, and it is even more crucial when it comes to computing. Your computer’s time is vital for logging purposes, scheduled jobs, and other important processes.

Therefore, it’s essential to ensure that your system’s timezone is set appropriately. In this article, we will explore how to set or change the timezone on Ubuntu.

Checking the Current Timezone

Before changing anything, we have to know what our current timezone is. In Ubuntu, we can use the “

timedatectl” command to find out the current system timezone. This command is available in Ubuntu 15.04 and later versions.

To check the current timezone, type the following command into your terminal:

“`

timedatectl

“`

This command will display a lot of system information, including the current timezone. Look for the “Timezone” value, which should be somewhere in the list of output lines.

If you have multiple users on your system, make sure to do this while logged in as root or with sudo privileges to access the log files and cron jobs. Changing the Timezone Using the

timedatectl Command

To change the timezone on Ubuntu, we can use the “

timedatectl” command to set the system’s timezone. This command allows you to set the timezone by specifying the Region/City name or by the /usr/share/zoneinfo path.

If you want to change the timezone by specifying the Region/City name, use the following command:

“`

sudo

timedatectl set-timezone Region/City

“`

Replace “Region/City” with your desired timezone. For example:

“`

sudo

timedatectl set-timezone Asia/Dubai

“`

This command will set the timezone to Asia/Dubai. If you want to specify the timezone path manually, use the following command:

“`

sudo

timedatectl set-timezone /usr/share/zoneinfo/Zone/SubZone

“`

Replace “Zone/SubZone” with your desired timezone path, for example:

“`

sudo

timedatectl set-timezone /usr/share/zoneinfo/America/New_York

“`

This command will set the timezone to America/New_York.

Changing the Timezone by Reconfiguring tzdata

If you are using an older version of Ubuntu, you may not have the “

timedatectl” command available. In that case, you can change the timezone by reconfiguring the “tzdata” package.

To change the timezone using tzdata, run the following command:

“`

sudo dpkg-reconfigure tzdata

“`

This command will launch the tzdata configuration utility. Follow the on-screen prompts to select your timezone.

Changing the Timezone Using the GUI

If you prefer a graphical user interface (GUI) method, you can change the timezone using the System Settings application. To do that, go to the “Date & Time” tab, which you can find under “System Settings.” In the map, locate your region by clicking on it or by entering your region or city in the search bar.

Once you find your region, click on it to set it as your timezone.

Prerequisites

Before changing the timezone on Ubuntu, you need to be logged in as the root user or a user with sudo privileges. Otherwise, you will not be able to change the system’s timezone.

Conclusion

Timezone configuration is a standard task that most Ubuntu users will need to perform. Whether you are traveling to a new time zone, need to synchronize your system with a remote server, or just need to set your time zone, it’s essential to know how to do it.

In this article, we have covered several methods of changing the timezone on Ubuntu. By following these steps, you can ensure that your system’s time stays accurate, and your scheduled jobs and logs remain in sync with the rest of the system.

Checking the Current Timezone

When you’re working with Ubuntu, it’s essential to ensure that your system’s timezone is set correctly to avoid any problems that may occur from inaccurate time and date information. The system may experience incorrect timestamps while logging events, failed cron jobs scheduling, and discrepancies with remote servers.

Checking the current timezone on Ubuntu is quite simple and can be done through the command line interface or by inspecting the files storing the timezone data.

Using Timedatectl Command to Display and Set Current Systems Time and Timezone

One of the most common methods of determining the current timezone on Ubuntu is using the “

timedatectl” command. The “

timedatectl” command is a utility that allows the user to set and view the current system date and time. To obtain the current timezone on Ubuntu using this command, open up your command-line interface and enter the following command:

“`

timedatectl

“`

This command retrieves information about the current system date and time settings, including the current timezone. Once you execute the command, you will see an output that displays various system information, including the current timezone.

Under the “Timezone” section, you should see information on the current timezone setting on your Ubuntu machine. By default, Ubuntu uses Coordinated Universal Time (UTC) as its standard timezone.

However, you can customize the timezone on your system by creating a symlink to the appropriate timezone configuration file. Alternatively, you may wish to compare your system’s timezone against an independent standard or use a specific timezone that differs from your local area.

Displaying Contents of /etc/timezone File to Check Current Timezone

Another quick method to check the current timezone on Ubuntu is to display the contents of the “/etc/timezone” file. To display the current timezone details stored within the file, open your command-line interface and enter the following command:

“`

cat /etc/timezone

“`

The output of the command should provide you with the current timezone saved within the file.

The details displayed should match the current timezone specified within the Ubuntu system.

Changing the Timezone Using the Timedatectl Command

Changing the timezone on Ubuntu is relatively easy, and the preferred method is using the “

timedatectl” command. To change the timezone using the command, you must first identify the specific timezone that you want to set as the system’s current timezone.

Finding the Long Name for Timezone

Before you can change your Ubuntu system’s timezone, you’ll need to know the name of the timezone you want to use. Most timezone names follow the “Region/City” format, where “Region” refers to the country or general area, and “City” denotes the specific region within the country.

For example, “Europe/Rome” represents the timezone for the city of Rome in Italy.

Listing Available Time Zones

Once you know the timezone you want to set, you need to list available time zones to ensure that your selected timezone is available. You can list available time zones using the “

timedatectl” command or by browsing the “/usr/share/zoneinfo” director. To list the available time zones using the “

timedatectl” command, enter the following command:

“`

timedatectl list-timezones

“`

The command will display a list of geographical regions under which Ubuntu organizes the available time zones. Regions are organized in alphabetical order and include cities or countries listed alongside them.

Alternatively, you can list available time zones by browsing the files in the “/usr/share/zoneinfo” directory. To do so, enter the following command:

“`

ls /usr/share/zoneinfo

“`

Once you execute this command in your terminal, you will see a list of all available time zones.

Running Commands to Change Timezone

After finding the long name for your desired timezone and verifying its availability, you can use the “

timedatectl” command to change the timezone on Ubuntu. Enter the following command, replacing “Region/City” with the timezone you want to set.

“`

sudo

timedatectl set-timezone Region/City

“`

After running this command, you may need to enter your user’s password. If successful, you should see that the system timezone has been successfully changed.

Verifying Changes Using Timedatectl

After setting the new timezone, use the “

timedatectl” command to verify that the new timezone is set correctly. Type the following command to view the system status:

“`

timedatectl

“`

The output of the command should show the new timezone set up as the current timezone. To confirm that the changes have been made, you can also check the contents of the “/etc/timezone” file.

Conclusion

Changing the timezone on Ubuntu is a straightforward process that can be done using the command line interface or the graphical user interface. Understanding how to find, check, and change your system’s timezone will help ensure that your system logs, scheduled jobs, and time-sensitive applications run accurately.

By using the “

timedatectl” command, you can easily change the timezone on your Ubuntu system and ensure it aligns with your preferences.

Changing the Timezone by Reconfiguring tzdata

If you are using an older version of Ubuntu and don’t have the “

timedatectl” command available, you can change the timezone using the “tzdata” package. Tzdata is a system library used to manage timezones and is installed on most Unix-based systems, including Ubuntu.

If you want to change the timezone using tzdata, you can do so by entering the following command in your terminal:

“`

sudo dpkg-reconfigure tzdata

“`

This command will launch the tzdata configuration utility, where you can select your new timezone using a list of available options. You can use your arrow keys or the Tab key to navigate the menu and highlight your desired timezone, then press Enter to confirm your choice.

Upon selecting your preferred timezone, your system will update its timezone settings accordingly. It is important to note that if you’re trying to change the timezone on a server that is in a different location from where it was initially installed, you should make sure to update the time before changing the timezone.

Otherwise, the system may experience inaccurate time readings that could cause problems down the line.

Changing the Timezone Using the GUI

Another way to change the timezone on Ubuntu is through the graphical user interface (GUI). The system settings window provides access to various settings and configurations that users can adjust, including changing the timezone.

To access the GUI method to change the timezone, open your system settings window by clicking on the “System Settings” application in the launcher or typing “System Settings” in the search bar. Then click on the “Date & Time” tab, and you should see a large map, which displays various time zones from around the world.

Locate your current timezone by clicking on your region, such as Europe, Africa, or Asia, or search for your region or city in the search bar. Once you find your location, click on it to set it as your default timezone.

You can confirm whether the system has applied the changes by checking the time displayed in the top right corner of the screen. It should now update to reflect the new timezone you set.
