Well, usually it makes sense to have the in-game time run faster than the real world time, to avoid that people in one timezone always have to play in the same in-game daytime when they always play during the same real-world daytime. Let's assume they all play in the afternoons or evenings of their timezone (after coming back from work, school, etc.), but in game, some would always play in in-game mornings, some always in in-game nights... depending on the timezone difference to the server time. How inconvenient. Especially when NPCs might have a daily cycle related to the in-game daytime ... oh wait, that already happened, NPCs started to "go home at night", remember? Now they don't enter their homes anymore.
