Most people don't understand the knowledge points of this article "how to modify linux time zone", so Xiaobian summarizes the following contents for everyone. The contents are detailed, the steps are clear, and they have certain reference value. I hope everyone can gain something after reading this article. Let's take a look at this article "how to modify linux time zone".

Methods: 1. Use commands such as "sudo rm -f /etc/localtime" to modify the system time zone;2. Use Systemd to change the Linux system time zone, with the syntax of "sudo timedatetl set-timezone 'timezone'".

Operating environment: Linux 7.3 system, Dell G3 computer.

How to change linux time zone

If your Linux system time zone is not configured correctly, you must manually adjust it to the correct local time zone. NTP time synchronization only calculates the offset between local time and UTC time, so configuring an NTP to synchronize time does not solve the problem of incorrect time zones. Therefore, when you use foreign cloud computing service providers such as Microsoft Azure or other VPS and virtual machines, you need to pay attention to whether it is consistent with the time zone of the mainland of China.

View Linux current time zone

You can easily check the current time zone of your Linux system by using the following command:

datels -l /etc/localtime

Get Time Zone TZ Value

To change the Linux system time zone, you first need to know the TZ value of your local time zone. Use tzselect command to view and select the installed time zone file.

Execute tzselect command

Choose your continent, country and city via the wizard

tzselect will eventually print out your time zone value in Posix TZ format (e.g. Asia/Shanghai) and record it.

Change the time zone for each user

Linux users A multi-user system, each user can configure their own time zone, you can add a TZ environment variable for yourself:

export TZ='Asia/Shanghai'

After execution, you need to log in again or refresh ~/.bashrc to take effect.

source ~/.bashrc

Change Linux system time zone

To change the system-wide time zone of a Linux system, use the following command:

sudo rm -f /etc/localtimesudo ln -s /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

Note: Please replace the specific time zone in/usr/share/zoneinfo/Asia/Shanghai with the TZ value obtained by yourself.

Change the Linux system time zone using Systemd

If your Linux system uses Systemd, you can also use the timedatetl command to change the Linux system-wide time zone. Under Systemd, there is a system service called systemd-timed that adjusts the system clock and time zone, and we can configure this system service using the timedatetl command.

sudo timedatectl set-timezone 'Asia/Shanghai'
