DateTime.TryParse century control C#

Question

The result of the following snippet is \"12/06/1930 12:00:00\". How do I control the implied century so that \"12 Jun 30\" becomes 2030 instead?

I'd write a re-usable function:

public static object ConvertCustomDate(string input)
{
    //Create a new culture based on our current one but override the two
    //digit year max.
    CultureInfo ci = new CultureInfo(CultureInfo.CurrentCulture.LCID);
    ci.Calendar.TwoDigitYearMax = 2099;
    //Parse the date using our custom culture.
    DateTime dt = DateTime.ParseExact(input, "MMM-yy", ci);
    return new { Month=dt.ToString("MMMM"), Year=dt.ToString("yyyy") };
}

Here's my list of quasi-date strings

List dates = new List(new []{
    "May-10",
    "Jun-30",
    "Jul-10",
    "Apr-08",
    "Mar-07"
});

Scan over it like so:

foreach(object obj in dates.Select(d => ConvertCustomDate(d)))
{
    Console.WriteLine(obj);
}

Notice that it handles 30 as 2030 now instead of 1930...
