Change Time and Timezone on Oracle Linux 8

 In this blogpost we will see how can we change the time and time zone on Oracle Enterprise Linux 8 Server

Check the existing configure time and time zone  on Server:

[root@OEL8-Server1 ~]# date

Mon Mar 13 06:47:05 EDT 2023

[root@OEL8-Server1 ~]# timedatectl

               Local time: Mon 2023-03-13 06:47:46 EDT

           Universal time: Mon 2023-03-13 10:47:46 UTC

                 RTC time: Mon 2023-03-13 10:47:48

                Time zone: America/New_York (EDT, -0400)

System clock synchronized: no

              NTP service: active

          RTC in local TZ: no

As you can see NTP service is active it will not allow to change time manually.

 

[root@OEL8-Server1 ~]# timedatectl set-time 13:48:33

Failed to set time: NTP unit is active

Enable local time zone update and disable NTP:

 

[root@OEL8-Server1 ~]# timedatectl set-local-rtc true

[root@OEL8-Server1 ~]# timedatectl set-ntp false

Set new time using timedatectl command:

[root@OEL8-Server1 ~]# timedatectl set-time 13:50:12

[root@OEL8-Server1 ~]# date

Mon Mar 13 13:50:14 EDT 2023

 

Change timezone:

Currently configure timezone is America/New_York (EDT, -0400). This has to be changed to Asia/Riyadh

This can be chaged again using the timedatectl command:

[root@S3T-IPEODBL1 ~]# timedatectl list-timezones | grep Riyadh

Asia/Riyadh

[root@S3T-IPEODBL1 ~]# timedatectl set-timezone Asia/Riyadh

[root@S3T-IPEODBL1 ~]# timedatectl

               Local time: Mon 2023-03-13 20:52:05 +03

           Universal time: Mon 2023-03-13 17:52:05 UTC

                 RTC time: Mon 2023-03-13 20:52:04

                Time zone: Asia/Riyadh (+03, +0300)

System clock synchronized: no

              NTP service: inactive

          RTC in local TZ: yes

 

Done :)

Thanks for reading. Hope it helps.
