@dawngreeter you can influence this by picking your season to run it in too, if the city is far enough north or south.
Want it to feel frenetic? Run over midsummer equinox and limit how much twilight they can stand. Where I am, that gives you 9 hours to fit everything you need to do into your day. Do you really want to drive out to the outskirts, what with that two hour long trip there and back? Oh, hunting didn't go well and took 3 hours? Well, then I guess you can't spend as much of the night finishing that project as you thought.
And the inverse works too - in winter you could get 14 hours, longer if its cloudy....
