6929 x.d = x.dst(), and assuming that doesn't raise an exception or
7065 a dst() offset, and starting *from* a time already in DST (we know z.d != 0),
7066 would have to change the result dst() returns: we start in DST, and moving
7087 and we would have stopped then), and there are only 2 possible values dst() can
7090 two possible dst() outcomes, one zero and the other non-zero). Therefore
7117 small dst() may get within its bounds; and it doesn't even matter if some
7118 perverse time zone returns a negative dst()). So a breaking case must be
