I recently returned from a roadtrip out to British Columbia. Throughout the trip, my Model S adjusted to the various time zones flawlessly. Until I got home to Saskatchewan, that is. I've been home for 6 and a half days now (let's say a week) and the time is still out by an hour! I've reset both screens, browsed the web and otherwise made use of the car's 3G connection to trigger a time zone request...yet, the time remains incorrect. What does a Model S use to determine its time anyway? The Cellular network? GPS? Both show the correct time on their respective devices, yet the car does not. The only thing I can think of is that my town is right on the border of two provinces (both with their own time zone) and it must not consider me to be far enough east to change over to CDT (the correct zone for my region). My location wreaks havoc with my satellite TV service, for example. I've read earlier threads about people having the incorrect time for a bit after the DST change but, like I mentioned earlier, it's been a WEEK now. That's a bit much, don't you think? What am I supposed to tell inquiring parties? "Sorry, my car from the future has trouble with its clock."
