How to handle vague dates in .Net

I have a system that takes information from an external source and then stores it to be displayed later.

One of the data items is a date. On the source system they have the concept of a fuzzy date i.e. not accurate to a specific day or sometimes not to a month as well. So I get dates in the format:

dd/mm/yyyy
mm/yyyy
yyyy

I can parse these to DateTime objects and work with these but when rendering later I need to be able to determine the accuracy of the date since parsing "2010" will result in a date of "01/01/2010". I want to show just the year so need to know it's original accuracy.

I've mocked up a quick class to deal with this:

public class FuzzyDate
{
    public DateTime Date { get; set; }
    public DateType Type { get; set; }
}

public enum DateType
{
    DayMonthYear,
    MonthYear,
    Year
}

This will do the job for me and I can do something on the parse to handle it but I feel like this is probably quite a common problem and there is probably an existing cleaner solution.

Is there something built into .Net to do this? I had a look at the culture stuff but that didn't quite seem right.

Any help would be appreciated.
