Command to change timezone in Ubuntu 20.04 server

If you have ever traveled somewhere and need to change the Timezone in Ubuntu 20.04 Desktop or Server OS, then here are the steps to follow.

There are two types of clock used by our system, one is software clock and another one is hardware. Software clock is the time within the Linux kernel. It is important for all users and the operating system itself and defines the system time that is valid for all programs during operation. It is also sometimes referred to as the operating system clock or the system clock. Whereas Hardware clock also called real-time clock, battery-backed clock, real-time clock (RTC), BIOS clock, or CMOS clock) is a clock that runs independently of all other components, even if the computer has been shut down. When switched off, it continues to run and is used to synchronize the software clock when the system is started.

However, the Time zone defines the area and the particular time in that vicinity, as we know due to earth rotation, all the places on earth don’t have the same time for sunrise and sunset. Thus, scientists have divided the earth’s Time into zones that represent and know as Time zones. So, if few are moving from one country to another then we have to change our Time zone either manually or the system must do that automatically.
