I travel from the west coast to the east coast regularly and retain my sleep schedule...but the app adjusts to the local time and continues to try to shift my pattern by 3hrs. I ignore it, but this should be fixed... Polyphasic sleep is awesome because I DONT need to adjust my sleeping for new time zones. It would be nice if the app supported this too.
