Keeping the Peace

I was doing the quest to keep the peace and I beat the dude at dice. After that the game didn’t continue the quest. I left it running as a looked up online and some people said I have to wait till nightfall but I can’t wait. It says I can’t delay. So I decided to do some shit as i waited for nightfall. I ran and fixed up my swords at the grindstone, then i did some sword training, and after all that I left the game run for an hour and time doesn’t seem to be passing. Some places online said it was suppose to automatically make it night, but I am not sure if it was a bug or just the fact that I need to wait more. So I guess if you know what is going on I would appreciate your impute.
