user4127: By looking at the uci option file of Stockfish 10 I found this line:
o["nodestime"]             << Option(0, 0, 10000);

How exactly does one use nodestime?

has everything you need. Essentially, it's an option for chess engine testing, not for production use. The option ensures the engine plays perfectly equally during development.
As a user, you shouldn't bother with this option because number of nodes per ms is not something easy to give a value.
