I can see it work. As long as there aren't any unique occurrences at a certain time, like mobs spawning only at night, like skellies and undead. But, undead could spawn anytime indoors to fix that.

Have the data center's time zone match in game time. So the western US data center would follow PST, whereas the eastern seaboard would follow EST.

We can't have any of that "stores are only open at certain hours" stuff. Otherwise, someone who works 5 days a week 1st shift will never be able to use the shops.
