How to Change System Date and Time in Ubuntu Linux?

Published by: Alex George on January 09, 2025

This weekend was great as I established a Local Area Network in my friend's home. He has a total of six computers, and two of them are running on Ubuntu Linux.

After creating the Local Area Network, we implemented one propitiatory real-time simulation software on this LAN by installing the software on all these computers. The software worked fine with the integrated data from 5 computers, but one computer was not connecting.


It seems one Linux PC rejected the connection.


So, the techie in our mind got up, and we started troubleshooting the issue.

At first, we thought the issue was with the compatibility issue of Ubuntu and the software. But the first Ubuntu computer was working fine with the software, and in a careful analysis, we found that that computer was functioning more efficiently than other Windows-based computers. So, it was not the issue with Ubuntu.


So, what would be the actual cause of the issue?


Then I just checked the connection manager of the software, and the error message was something like an unpredictable date with many hexadecimal codes.

So it has something with the system date. We went to the non-functional computer and checked the system date. It was the default system date set when installed Ubuntu. So we just set the system date and time with the current date and time. The result was promising.

It fixed the problem. So here I am presenting steps to change computer date and time in Ubuntu Linux when there are no date and time displays on the system tray.





How to change system date and time in Ubuntu Linux?

I read the comments I received, and some readers asked me to explain the steps I did on the sixth computer. John Munro asked this question.

What I did on the Ubuntu PC was to set the correct system date. Sidharth Ramkumar and Waseem Jabbar Khan asked me to explain how I changed the system date. So, let me explain the steps here.

  1. Click on Show Applications (at the left-bottom).

  2. Click on the Settings.

  3. Click on Date and Time (from the left side menu).

  4. To manually change the time and date, turn off the Automatic Date and Time.

  5. Now click on the date and time. You can change the Ubuntu Date and time.
