Description

The DateFormat class handles January incorrectly. According to the docs, dates use a zero-based numbering system, but the dateFormat classes parses a month of "1" into January anyway. It parses the other dates correctly, which is to say that a month of 2 is March, 3 is April, etc.

For example, if you run the following block of code:

var formatter:DateFormat = new DateFormat("m/d/Y");
var dateString:String = "1/25/2008";
var date : Date = formatter.parse(dateString);
var dateFormatter : DateFormatter = new DateFormatter();
dateFormatter.formatString = "MMMM D, YYYY";
trace(dateFormatter.format(date));

The output is "January 25, 2008".

However, if you change the date to "2/25/2008", the output is "March 25, 2008."

I'd prefer seeing the months OTHER than January adjusted to use a 1-based array (so 2 is February, 3 is March, etc.) to make it easier to load data from an external file or text input or whatever, parse it in 1 line, and return an accurate date object. With the zero based array I need to adjust the months. Either way you choose to implement this it should be consistent across all months.
