Thanks for reviewing! We could exclude the time endpoint for now - I only included it since it appeared in my report of the required commands for the assessment files here.

I would leave it in as a no-argument call to get the current simulator time, which already works, and we can add a "set time" endpoint later if necessary.

I've made that change and updated the API docs 👍
