@cody6268 I've had that setting on for a long while. I can't play without it anymore. Mine is set to 50. I like that my sims actually have time to go places and it's not just go to work fill needs and sleep. I tried playing with it off when I was waiting on MCCC to update and everything felt so rushed.
One thing I will note is that your calendar times will be off schedule for about two sim weeks. School, festivals, etc. It will sort itself out though. That doesn't happen if you play on a new save though.
