Hello,
  Is there anywhere I can get the UTC datetime from the GPS?

Thanks.

Hello

The actual implementation of TnrGps component does not decode UTS field reply of GGA GPS command.

But you can get necessary info after handling TnrGps.OnGpPacket event:

procedure TForm1.nrGps1GpPacket(Sender: TObject; Command: TnrGpsCommands;
  Fields: TStrings; var Skip: Boolean);
begin
  if Command = TnrGpsCommands.gpsGGA then begin
     OutputDebugString(PChar('Datetime =' + Fields[1]));
  end;
  Skip := false;
end;


You can decode string Fields[1] and get Hours Minutes and Second.


I hope we will include UTC time decoding in the next version of library.

Hello

Full DATETIME info is available after  ZDA request to GPS device.

you can try to decode the ZDA reply in GPS command handler:

procedure TForm1.nrGps1GpPacket(Sender: TObject; Command: TnrGpsCommands;
  Fields: TStrings; var Skip: Boolean);
begin
  if Command = TnrGpsCommands.gpsZDA then begin
     OutputDebugString(PChar('Time =' + Fields[1] + ' Date:' + Fields[2] + '-' + Fields[3] + '-' + Fields[4] + ' local zone:'+ Fields[5] +':' + Fields[6] ));
  end;
  Skip := false;
end;

We will add a more suitable way in the next release.
