Date/Time
The Date/Time box provides settings for time format
(local or UTC; 12- or 24-hour) and time offset. The time
offset is used to define current local time. UTC (also called
"GMT" or "Zulu") date and time are calculated directly
from the GPS satellites signals and cannot be changed. If
you prefer to use local time, simply designate the offset by
adding or subtracting the correct number of hours.
The Date/Time section of the System Setup page
displays the following data:
• The current date
• The current time
• The current time format (local 12hr, local 24hr,

Display Units
The Display Units section of the System Setup Page
allows you to configure the displayed data to standard or
metric units of measure. The Display Units section also
provides two magnetic variation (heading) options: True
and Auto. If 'Auto' is selected, all track, course and heading
information is corrected to the computed magnetic
variation. The "True" setting references all information to
true north.
The Display Units section of the System Setup Page
displays the following data:
• Nav Angle
• Magnetic variation
• Distance and speed units
• Altitude and vertical speed units
• Barometric pressure units
• Temperature units
• Fuel and fuel flow units
The aviation database contains over 100 map datums
to adjust your position reading, making it conform to
specific paper charts. The default datum setting is WGS
84. If you are using a chart based on another datum, you
should set the G1000 to use the same datum. Using a map
datum that does not match the charts you are using can
result in significant differences in position information.
If you are using the paper charts for reference only, the
G1000 still provides correct navigation guidance to the
waypoints contained in the database, regardless of the
datum selected.
