It is possible to construct invalid dates (eg 123/-5/12.4). Behavior in this case is undefined.

If 'str' is given, it will be used instead of month, day, and year. 'str' should be in the format 'M [sep] D [sep] Y'. M, D, and Y can be any number of digits long. Whitespace anywhere will be ignored, as long as it doesn't occur in the middle of a number.
