Go to System Prefs,/International/Formats. Hit the "customize" button next to "Dates" and configure that however you like. Then copy the entire date bar, hit the "customize" button next to "Time" choose "medium" formatting, and paste the date next to the time there. You can add spacing between the elements, just like regular text.
