Time Zones and UTC Time Offset
The StreetPilot 2610/2650 has many time zones built into memory. To display the correct local time,
simply choose the corresponding time zone. Internally, the StreetPilot 2610/2650 does the necessary
“offset” calculations to convert from UTC (Coordinated Universal Time) to selected local time zone.
To select a time zone:
1. Press unit or remote MENU to select the Main Menu, then select ‘Options’.
2. Select the ‘Time’ fi le tab, then select the ‘Time Zone’ fi eld to display a list of available time zones.
3. Select the desired time zone and press ENTER.
If the desired time zone is not pre-programmed into the StreetPilot 2610/2650, you’ll need to enter the
time offset manually. To do this, select ‘Other’ as the time zone. Once selected, a ‘UTC Offset’ fi eld appears
directly adjacent to ‘Other’, allowing you to manually enter the difference between UTC and the local time
zone.
To manually enter a time zone offset:
1. Follow the steps above and select ‘Other’ in the ‘Time Zone’ fi eld.
2. Select the ‘UTC Offset’ fi eld, then use the enter the desired offset amount.
3. Select ‘OK’ when fi nished.
If you are not certain what the offset is between UTC and the local time zone, experiment. Simply enter
incremental offset values until the correct local time appears. To aid this endeavor, keep in mind that as
you move West of the Prime Meridian (0° longitude) the offset is negative (-), and as you move East of the
Prime Meridian the offset is positive (+). In other words, it is earlier in the day when you move West and
later in the day when you move East.
Many time zones are pre-programmed into your
StreetPilot 2610/2650 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.
