Node Red Engine Hours timer

Thats beyond me Paddy - I haven't touched a database since Microsoft Access 20 years ago.

I do like the idea of integrating it with a LogBook so, just for fun, I have added a log function which writes out Engine hours to a text file. /home/pi/NavPi.txt
(If anyone wants to use it, you do need to load the Moment.js Node through Palette manager)
