If you have permafrost, there are many, many other issues to deal with. (I live in/near permafrost). I think what you are referring to is that in most areas, you are required to extend the foundations below frost depth.
Oh, and November 19th in Barrow would be ~1,560 hours long, and you would you just skip those 65 days? Or you could have November 20th in Barrow while it is different dates in other parts of the world?
Live in Fairbanks, Alaska. There is no way this system would be feasible at northern latitudes. The days get longer/shorter at a rate of ~7 min. a day. Instead of an hour time change twice a year, it would be equivalent to an hour time change once a week. (and in december, it would get dark at 11:30am)
