But it certainly seems that despite this EKOS thinks it is about 6 hours later than it should be! Again the odd thing is that when I run directly from the Win10 laptop and bypass the RPI everything works as expected. SO - is there another way I can check to see if the time from the RPI is being passed correctly to EKOS?
