What's the best way to set Raspberry PI time from NMEA
(connection from USB/NMEA adapter
or over the network via data from a NMEA 2000 Wifi Gateway
Use Case: I return to my boat
after several days or longer and power
up the Raspberry Pi I use for navigation
. I don't have internet
connection so I want the clock to be set from one of my GPS
devices. My AIS
transponder, with GPS
, is connected via USB/NMEA adapter. NMEA
data including GPS time is also available over the boat's wifi
via NMEA 2000 Wifi
I've set time on another Raspberry PI via an inexpensive USB GPS
and GPSD software
but I don't have a spare USB port.
I've searched this forum and broader internet
with no luck.
Thanks in advance for your help!
