I enjoyed clicking on the buttons and seeing what they did. The person who made them must be a genius. And very handsome. :P
The Test Time Change was a bit bugged, though. When I added 10 or 30 minutes, starting at 5:00 AM, it suddenly was Night, even though the time was still 5:10 AM or 5:30 AM. When I added one hour or three hours, it was properly still morning. Weird.
