How to add time stamp to posts for Chateau theme

Hello, I have searched high and low and I cannot figure out how to add the timestamp to my posts for my current theme. I am currently using the theme Chateau, and it lists the day, date and year but I would also like to add the time that my posts are published. I’m pretty new to using css and all but I did try adding it to the section in settings but it did not work. Here is a link to my blog: bit.ly/1hG3boP

Any info is appreciated.
