Setting the Time and Date
The following procedure is used to enter the time and date. The NMC
uses a real time clock set to Universal Coordinated Time
(UTC—formerly called Greenwich Mean Time). The correct UTC
must be entered for GPS sensors to initialize. During the power-up
sequence, the NMC briefly displays the current time and date. The
time and date may also be adjusted during the power-up sequence. The
NMC will update itself from GPS satellite data during power-up after
it gets a 3-D fix. For the procedure used to adjust the time and date
during power-up, see Operations, Power-Up Sequence.
