This minHour teaches you how to change the time zone on a Linux computer. You can change the timezone on every Linux distribution by using the command line, or you can use the selection menu in the command line for different Linux distributions. If you're using Mint, Ubuntu, or any other distribution with a simple user interface and settings menu, you can also change the time zone settings from there.
Using the Command Line
Open Terminal.
Select the Terminal program from your Linux programs, or press Ctrl+Alt+T on your keyboard.
Check your current time zone.
Type date into Terminal and press ↵ Enter. The terminal will display the date in Weekday Month Day Time TimeZone Year format.
- For example, you might see something like Wed Mar 7 07:38:23 EDT 2017 wherein “EDT” refers to the current time zone (Eastern Daylight Time).
Check available time zones.
Type in cd /usr/share/zoneinfo and press ↵ Enter, then type in tzselect and press ↵ Enter to display a list of locations.
- The /usr/share/zoneinfo directory may vary depending on your Linux distribution.
Select a continent or ocean.
Type in a selection number that pertains to your general location, then press ↵ Enter.
Select a country.
Type in a selection number from the on-screen list and press ↵ Enter.
Select a time zone.
Type in a selection number to select the preferred time zone region and press ↵ Enter.
- If your city is not listed in the time zone list, pick a different city from your same time zone.
Confirm the local time.
In the following prompt, confirm that the local time is correct by typing 1 and then pressing ↵ Enter.
- If the time isn’t correct, type in 2 and press , then select a new continent and repeat the process.
Verify that your time zone has been set.
Run the date command again and check that the time zone corresponds to the one you just changed to. If you see you new time zone listed, you have successfully changed your computer’s time zone.
Set your clock to stay synced with internet time servers if you like.
Most modern distributions have NTP already installed. If your Linux distribution does not, you will need to install the NTP server package. Use the following commands to install it, depending on your Linux distribution:
- Ubuntu/Mint/Debian: sudo apt install ntpdate
- CentOS: sudo yum install ntpdatesudo /sbin/chkconfig ntpd on
- Fedora/RedHat: sudo yum install ntpdatesudo chkconfig ntpd on
- Enter ntpdate server link && hwclock –w after the installation command, making sure to enter the link to the website in place of server link.
Using the Timezone Selection Menu
Open Terminal.
Select the Terminal program from your Linux programs, or press Ctrl+Alt+T on your keyboard.
Enter the time zone menu command.
Depending on your Linux distribution, this command will vary:
- Ubuntu and Mint – sudo dpkg-reconfigure tzdata followed by the admin/user password.
- Redhat – redhat-config-date
- CentOS and Fedora – system-config-date
- ‘FreeBSD and Slackware – tzselect
Select your geographic area.
Use the arrow keys to select the geographic area the country is found in, then press ↵ Enter.
Select your city/region.
Select the city or region corresponding to your time zone, then press ↵ Enter. This will change the time zone on your system.
Using the Graphical User Interface in Ubuntu
Click the “System Menu” icon.
It’s a combined group of Power, Volume and Networking icons in the upper-right corner of the screen. A drop-down menu will appear.
Click the “Settings” icon.
This gear-shaped icon is in the upper-left corner of the drop-down menu. Doing so opens the Ubuntu Settings.
Click Date & Time.
You’ll find this tab on the left side of the window.
Turn off Automatic Time Zone.
Click the blue “Automatic Time Zone” switch in the middle of the page to do so.
- If the “Automatic Time Zone” switch is grey, skip this step.
Click Time Zone.
It’s near the bottom of the window. Doing so opens the Time Zone menu.
Select a time zone.
Click your approximate location on the world map to do so. You should see the time change to match the selected area’s time zone.
Close the window.
This will save your settings and update your time zone accordingly.
Using the Graphical User Interface in LinuxMint
Open the Menu.
Click in the bottom-left corner of the screen.
Click the System Settings icon.
It’s made of two grey cogs. You’ll find it on the left side of the Menu window.
Click Date & Time.
It’s in the “Preferences” group of options.
Select a time zone.
Click a vertical slice of the map to pick that time zone. You should see the clock on the right side of the page immediately change to reflect the selected time zone’s time.
Enter your user password when prompted.
If you have logged in as an Administrator, you may not need to enter password. In case you have logged in as a Standard user, type in the Administrator password. Super user privileges are required to make any changes to time zone settings.
Click Authenticate.
It’s at the bottom of the prompt. Doing so unlocks the Date & Time menu.
Tips
- On some versions of RedHat Linux, Slackware, Gentoo, SuSE, Debian, Ubuntu, and anything else that is “normal”, the command to display and change the time is “date”, not “clock”.
- On mobile phones and other small devices that run Linux, the time zone is stored differently. It is written in /etc/TZ. Edit this file manually or use echo (for instance, echo GMT0BST > /etc/TZ to set the the timezone of the United Kingdom).
Warnings
- Some applications (such as PHP) have separate timezone settings from the system timezone.
- On some systems, there is a system utility provided that will prompt for the correct timezone and make the proper changes to the system configuration. For example, Debian provides the “tzsetup” or “tzconfig” utility.
