It would be really nice if there were a way to formally change your time zone. I know it would complicate things, but I would even be happy if I could reset my streak to 0 or only do it once a year, or something. I think I'm fairly sure I signed up yeaaaars ago in Canada, but I've since immigrated to Australia. It's really frustrating to try and figure out what time it is back in my old province all the time. Especially around daylight savings or whatnot, which doesn't match up! It's really frustrating losing a streak or a streak freeze when I've been playing consistently.
