Time Settings
Time Format allows current time to be displayed using a 12- or 24- hour clock. This
field is also used to select between local and UTC time readouts.
To select a time format:
1. Highlight the ‘Time Format’ field and press ENTER to display the available options.
2. Select ‘Local 24hr’ or ‘Local 12hr’ to display local time references. ‘Local 12hr’ will show current
time using a traditional AM/PM format, OR
3. Select ‘UTC’ to display universal time references (also referred to as ‘Greenwich’ or ‘zulu’ time).
Local Time Zone is used to define the current local time. UTC date and time are calcu-
lated directly from the satellites’ signals and cannot be edited. If you prefer to use local
time, you may designate an offset, either ‘Behind UTC’ or ‘Ahead of UTC’. The offset is
the difference, in hours and minutes, between local time and UTC time.
To enter the local time zone:
1. Highlight the ‘Local Time Zone’ field and press ENTER.
2. Select the desired offset amount (in hours and minutes) using the rocker keypad and press ENTER.
3. Highlight the offset direction field (immediately to the right) and press ENTER.
4. Select ‘Behind UTC’ or ‘Ahead of UTC’ (as appropriate) and press ENTER.
Time displays the current time based on the settings made above and information
provided by the satellites received.
Date displays the current date based on the settings made above and information
provided by the satellites received.
Enter an offset amount to
adjust the time display to
your local area. In the United
States, all offset amounts will
be ‘Behind UTC’.
If you’re unsure of the exact
offset, select a ‘Local’ time
format, then enter offset
values until you arrive at the
correct local time.
