59Appendix ETime OffsetTime Zones and UTC Time OffsetThe StreetPilot III has many time zones built into memory. To display the correct local time,simply choose the corresponding time zone. Internally, the StreetPilot III does the necessary “offset”calculations to convert from UTC (Coordinated Universal Time) to selected local time zone.To select a time zone:1. Press MENU twice to select the Main Menu, then use the ROCKER KEYPAD to select “SystemSetup” and press ENTER.2. Use the ROCKER KEYPAD to select the ‘Time’ file tab, then use the ROCKER KEYPAD to selectthe ‘Time Zone’ field.3. Press ENTER to display a list of available time zones. Then use the ROCKER KEYPAD to select thedesired time zone and press ENTER.If the desired time zone is not pre-programmed into the StreetPilot III, you’ll need to enter thetime offset manually. To do this, select ‘Other’ as the time zone. Once selected, a ‘UTC Offset’ fieldappears directly adjacent to ‘Other’, allowing you to manually enter the difference between UTC andthe local time zone.To manually enter a time zone offset:1. Follow the steps above and select ‘Other’ in the ‘Time Zone’ field.2. Use the ROCKER KEYPAD to select the ‘UTC Offset’ field, press ENTER, then use the ROCKERKEYPAD to enter the desired offset amount.3. Press ENTER when finished.If you are not certain what the offset is between UTC and the local time zone, experiment. Simplyenter incremental offset values until the correct local time appears. To aid this endeavor, keep in mindthat as you move West of the Prime Meridian (0° longitude) the offset will be negative (-), and as youmove East of the Prime Meridian the offset will be positive (+). In other words, it will be earlier in theday when you move West and later in the day when you move East.Many time zones are pre-programmed into yourStreetPilot III making display of local time simple.If the desired time zone is not pre-programmed, select‘Other’ and enter the offset from UTC to the local time.
