Hi Richard,
That's a very interesting question
I haven't checked it out myself, but 'night time' is defined by some entries in the route's .env file/s, although I would have thought the time the route goes dark will be controlled by the same entries, but we are talking about MSTS
Have a look at the second post here :

EDIT : Having a Google around reveals many fleeting references to this problem, but the most important being that Route Riter can set the appropriate sunrise/sunset times for each month based on the lat/long of the route. Again, I have not tested it, so don't know if it answers your question!
