9.7. Time Zone Configuration

Set your time zone by selecting the city closest to your computer's physical location. Click on the map to zoom in to a particular geographical region of the world.

Specify a time zone even if you plan to use NTP (Network Time Protocol) to maintain the accuracy of the system clock.

From here there are two ways for you to select your time zone:

Using your mouse, click on the interactive map to select a specific city (represented by a yellow dot). A red X appears indicating your selection.
You can also scroll through the list at the bottom of the screen to select your time zone. Using your mouse, click on a location to highlight your selection.

Figure 9.20. Configuring the Time Zone

If Red Hat Enterprise Linux is the only operating system on your computer, select System clock uses UTC. The system clock is a piece of hardware on your computer system. Red Hat Enterprise Linux uses the timezone setting to determine the offset between the local time and UTC on the system clock. This behavior is standard for systems that use UNIX, Linux, and similar operating systems.

Click Next to proceed.

Windows and the System Clock

Do not enable the System clock uses UTC option if your machine also runs Microsoft Windows. Microsoft operating systems change the BIOS clock to match local time rather than UTC. This may cause unexpected behavior under Red Hat Enterprise Linux.

Note

To change your time zone configuration after you have completed the installation, use the Time and Date Properties Tool.

Type the system-config-date command in a shell prompt to launch the Time and Date Properties Tool. If you are not root, it prompts you for the root password to continue.

To run the Time and Date Properties Tool as a text-based application, use the command timeconfig.
