Hmm, yes I see... my version is about spot on for the US (Indiana) while the XKCD version is about an hour and a half behind. I'm not sure what to do about it other than re-draw the map but thanks for pointing that out! Any suggestions? For now I just rotated the map so that the time will be based on the Greenwich Meridian instead of my local meridian.
