The KDE 3.5 Control Center - Part 10 - System Administration
Today's section, System Administration, covers a lot of administration of various features of KDE, including how it handles logins, date and time, and more. This is not for the fait of heart, and you can make a mess of things to the point of even locking yourself out of KDE. So tread with care. Now, let's look at each of the subsections in this area and look at what each one does.
Date & Time
The Date & Time section does exactly as the name implies. It allows you to configure your system date and time. It also allows you to configure its time zone. You'll need to start out by clicking on the "Administrator Mode" button at the bottom left of the window, then enter your root password when prompted. You'll now see that part of this window is surrounded by a red box. That indicates that you're now in root administration mode and to tread carefully.
At the top left of the window you'll see a checkbox titled "Set date and time automatically" with a drop down menu directly to the right. What this does is it goes out to one of several public time servers and gets the current time. Since this is sent in UTC (universal time clock) format, you'll need to have your time zone configured properly to make this set your time and date correctly. That can be done in the third window where it says, "To change timezone, select your area from the list below."
