You can set your time zone by selecting your computer's physical location or by specifying your time zone's offset from Universal Time, Coordinated (UTC).
Notice the two tabs at the top of the screen (see Figure 2-22). The first tab allows you to configure your time zone by your location.
On the interactive map, you can also click on a specific city, which is marked by a yellow dot; a red X will appear indicating your selection. You can also scroll through a list and choose a time zone.
The second tab allows you to specify a UTC offset. The tab displays a list of offsets to choose from, as well as an option to set daylight saving time.
Figure 2-22. Configuring the Time Zone
On both tabs, you can select System Clock uses UTC. Please select this if you know that your system is set to UTC.
To change your time zone configuration after you have completed the installation, click the Main Menu button and select System Settings > Date and Time (or type the redhat-config-date command from a shell prompt) to launch the Date/Time Properties tool. If you are not logged in as root, it will prompt you for the root password to continue.
