The case where a parsed date-time fell in a transition, but only because the default value for some field lead it there, only dealt with the case of parsing a date-time, which is the only time it should be relevant. However, since the date and time do get combined as a date-time (even when only one of them is relevant) the same problem could arise when parsing a date (on which the current time-zone happened to make a transition at the start of the day) or a time (if the default date happens to be one on which the current zone had a transition). So handle both of those cases, as well as the date-time case.
