- <h1>Choose Time Zone</h1>
-
- <p>
- The easiest method of selecting your time zone is finding your city
- on the map (or finding a city close to you that you know is in your
- time zone) and selecting it with your mouse. The pull-down list below
- the map will automatically update to the zone you chose in the map
- above.
- </p>
-
- <p>
- Alternately, you can bypass the map entirely and choose from the
- list. Click the arrow button to the right of the list and then
- browse to the city that is closest to your location.
- </p>
-
- <p>
- When you have chosen the time zone you wish to use, be sure to
- indicate if you use Greenwich Mean Time (GMT) or local time
- with your system's <em>hardware clock</em>. These two options are
- offered below the pull-down time zone list. (Note for the
- knowledgeable reader: we refer to GMT instead of UTC since this
- concept is more familiar with most people, and the subtle
- difference doesn't matter in this context.)
- </p>
-
- <p>
- Network operating systems usually have their hardware clock
- set to GMT, while systems like DOS and Windows prefer it set to
- local time. It is recommended that you use GMT unless you have
- one of the latter operating systems on the same computer.
- </p>
-
- <p>
- Specifying that the hardware clock is set to GMT will cause the
- system to adjust the time it reads from the hardware clock for the
- selected time zone and season. The local time setting will tell
- your Linux system to use the hardware clock's time without any
- adjustments. You will then have to adjust for daylight savings
- time changes manually.
- </p>
-
- <p>
- If your system time is off by a factor corresponding to your time
- zone, it is likely that you have selected the GMT setting while
- your hardware clock is set to local time. Check in your BIOS that
- the hardware clock is really set to GMT.
- </p>
-
- <p>
- Local time can be ambiguous with regard to daylight savings time.
- Thus, operating systems using local time sometimes disagree about
- which performs the adjustments, and do the changes to the hardware clock
- multiple times. Please recheck the hardware clock in your BIOS if
- your time setting is incorrect after one of these systems has
- performed any adjustments.
