Like many RPGs, Fallout: New Vegas has day/night cycles. Right now, I'm trying to infiltrate the REPCONN labs to find out why there are so many ghouls there, while still making it back to Novac in time to find out who's killing Bhramin.
I need to be in the Bhramin pen at midnight in order to catch the perp and it takes me about four minutes of real time to walk from REPCONN to Novac. I need to know when to leave to make my appointment.
What is the game-time to real-time ratio in Fallout: New Vegas?
