Animated backgrounds are based on a start time in local time - in case of a timezone change, that time is no longer accurate. To fix, we need to either make BGSlideShow aware of timezone changes (and notify us to update the animation), or just reload the animation - timezone changes should be a rare event, so go with the simpler second option. https://bugzilla.gnome.org/show_bug.cgi?id=758939
