In this article, I will show you how to change the Linux timezones setting.

Linux TimeZones Setting Kodekloud Engineer Task Details:

During the daily standup, it was pointed out that the timezone across Nautilus Application Servers in Stratos Datacenter doesn’t match with that of the local datacenter’s timezone, which is Africa/Abidjan.

Important Note:- Perform the below commands based on your question. The server, user name & other details might differ. So please read the task carefully before executing it.

Solution for Linux TimeZones Setting:

Step 1: To start with, login to App server 1.

$ ssh tony@stapp01

Enter the password provided to you using the documentation for authentication.

Step 2: Run the below command to check the existing Time Zone set for the app server.

$ timedatectl

Result:

Local time: Sat 2022-06-12 15:22:41 UTC

Universal time: Sat 2022-06-12 15:22:41 UTC

RTC time: n/a

Time zone: UTC (UTC, +0000)

NTP enabled: n/a

NTP synchronized: yes

RTC in local TZ: no

DST active: n/a

Here the time zone is set as “Time zone: UTC (UTC, +0000) “

Step 3: Run the below command to select the time zone. Make sure you enter the timezone provided in your question.

$ sudo timedatectl set-timezone Africa/Abidjan

Enter the password of the user if it asks you to authenticate again.

Step 4: Verify again if the timezone is changed or not.

$ timedatectl

Result:

Local time: Sat 2021-06-12 11:25:38 AST

Universal time: Sat 2021-06-12 15:25:38 UTC

RTC time: n/a

Time zone: Africa/Abidjan

NTP enabled: n/a

NTP synchronized: yes

RTC in local TZ: no

DST active: n/a

Important: You have to do this in all app servers stapp01, stapp02, stapp03. Here I have done it only on app server 1. Follow the same steps in all other app servers.

After setting the timezone for all 3 app servers click on submit and finish the task.
