Set date and time in CentOS 8

It is very important that the installed operating system has the correct date and time settings, since many programs running in the background (corn jobs) start at a certain time, and the log entries contain time stamps so that system events can be tracked in case of an error . And, of course, when working on the desktop, the clock should show the correct time 🙂

In this tutorial, we will show you how to set the date and time in CentOS 8 using the graphical interface, as well as using the shell (command line).

Step 1. Log into your system and click “Actions”, which is present in the upper left corner of the CentOS 8 desktop.
