Method 2: Launch From System -> Administration

If you don’t have the date & time displayed in the system tray, Click on System -> Administration -> Time and Date.

By default, this will show the date and time in the locked mode. Click on Unlock and then give the sudo user password. After unlocking you can change the date and time as shown below.

    Ok, so there might be people that could have problems with date time, but seriously, this one is really boring…

    Thanks for your feedback. I agree with you that this article is lame and boring. I’ll try to avoid such basic articles in the future.

    Problem with the lock function for time and date in Ubuntu is that every time I look for another date (when planning a trip for eg.) it asks me for my password. This is a real nuisance. Is it possible to get rid of this default setting or should I just download a normal calendar ?
