This is part of my complete guide to Setting up a CentOS Digital Ocean droplet with Nginx for beginners.

sudo timedatectl list-timezones #copy your zone sudo timedatectl set-timezone region/timezone sudo yum install ntp sudo systemctl start ntpd sudo systemctl enable ntpd
I am not going to bother repeating the excellent explanation of these commands from their source guide. If you are interested, check it out.
