Installing NTP Service and change timezone in CentOS 6 / CentOS 7 Rumi, August 30, 2019 Let’s install NTP service first: yum install ntp Configure NTP services by updating the following section (only if appropriate): nano /etc/ntp.conf And by commenting on the sections: # Use public servers from the pool.ntp.org project. # Please consider joining the pool (http://www.pool.ntp.org/join.html). #server 0.centos.pool.ntp.org iburst #server 1.centos.pool.ntp.org iburst #server 2.centos.pool.ntp.org iburst #server 3.centos.pool.ntp.org iburst In my case I used the following National Time Server of Bangladesh: server bsti1.time.gov.bd server bsti2.time.gov.bd save and restart the ntp service. Change Timezone on a CentOS 6 and 7 How do I see the current time zone on CentOS Linux? Type the date command or the ls command: $ date $ ls -l /etc/localtime Another option is to type the following command on systemd based distro such as CentOS 7 to see timezone along with the grep command and timedatectl command: timedatectl timedatectl | grep -i 'time zone' date Change the current timezone in CentOS 7 To find list of all available time zones, run: # timedatectl list-timezones ##*** Grep possible Asian timezones ***## # timedatectl list-timezones | grep Asia Sample outputs: Africa/Abidjan Africa/Accra Africa/Addis_Ababa Africa/Algiers Africa/Asmara Africa/Bamako Africa/Bangui Africa/Banjul .... .. America/Dawson America/Dawson_Creek America/Denver America/Detroit America/Dominica America/Edmonton America/Eirunepe America/El_Salvador America/Fortaleza America/Glace_Bay .... .. Pacific/Saipan Pacific/Tahiti Pacific/Tarawa Pacific/Tongatapu Pacific/Wake Pacific/Wallis The syntax is as follows to set timezone and need to run as root user: # timedatectl set-timezone time_zone In this example, set timezone to America/Chicago # timedatectl set-timezone America/Chicago Verify new settings by typing the following two commands: # date # ls -l /etc/localtime Change the current timezone in CentOS 6 and older You need to use the ln command to set timezone on Centos 6. Type the following commands as root: cp /etc/localtime /root/old.timezone rm /etc/localtime ln -s /usr/share/zoneinfo/America/Chicago /etc/localtime Verify new settings by typing the following two commands: date ls -l /etc/localtime Related Administrations Configurations (Linux) CentOSDateNTPTime Zone
