[Linux Basics] How to change time zone

If your Linux system time zone is not configured correctly, you must manually adjust to the correct local time zone. NTP synchronizes time processing only calculates the offset between local time and UTC time. Therefore, configuring an NTP to synchronize time does not solve the problem that the time zone is incorrect. Therefore, when you use a cloud computing service provider such as Microsoft Azure or other VPS or virtual machine, you need to pay attention to whether it is consistent with the time zone of your country.

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

By selecting your continent, country, and city through the wizard, tzselect will eventually output your time zone value in the Posix TZ format.

Change the time zone

You can add a TZ environment variable for yourself:

export TZ=’America/Pangnirtung’

source ~/.bashrc

sudo rm -f /etc/localtime
sudo ln -s /usr/share/zoneinfo/America/Pangnirtung /etc/localtime

sudo timedatectl set-timezone ‘America/Pangnirtung’
