So, I tried using a dateFormat of @"j:mm" and got nothing but ":" in the result. I tried passing @"j:mm" to -dateFormatFromTemplate:options:locale:, but the result is always "HH:mm", even when I have things set to 12-hour.
It seems that iOS does not properly honor "j" (behavior is the same on device and sim, but on the sim I can't set the format).
