How can you configure the Linux Server to use the 'Asia/Kolkata' timezone

 

Using Red Hat Enterprise Linux 9 (RHEL 9), how can you configure the system to use the 'Asia/Kolkata' timezone?

"In RHEL 9, set the timezone to 'Asia/Kolkata' using timedatectl. First, find the timezone with timedatectl list-timezones | grep Asia/Kolkata. Then, execute sudo timedatectl set-timezone Asia/Kolkata. This updates the system's timezone, taking effect immediately and persisting after reboots. timedatectl replaces older commands, offering a straightforward method for time management in Linux environments."
