Time

Time is a feature of The Sims games.

The Sims
In The Sims, there is a 12 or 24-hour clock system and it is very simple. There are no weeks in this series.

There are 3 modes of Speed. Normal, Fast and Ultra. There is also a Pause button to freeze the time

The Sims 2 and The Sims Stories
There is now a week system in The Sims 2 and The Sims Stories which effects what days Sims go to work. Bills are delivered to your house every Tuesday and Thursday. Exceptions to this are The Sims 2 University (If in University) and The Sims Castaway Stories.

The Sims 3 and The Sims Medieval
Time is same as earlier games but The Sims 3 and The Sims Medieval keeps track of days since you started the town, Mousing over the time will show how many days have passed since you started playing your town.
