This is so cool! But the coloring is a bit frustrating because -1 on the scale is just as red as -2 or -3 or more. So, for example, Western China is the region that is most disconnected from solar time. It's off by more than 3 hours. (Imagine a summer sunset at midnight, or a winter sunrise at 10am.) But it looks just as red as Saskatchewan, which is off by only an hour.
