Simply put, don't use DateTime.MinVaue as a default value.

There are a couple of different MinValues out there, depending which environment you are in.

I once had a project, where I was implementing a Windows CE project, I was using the Framework's DateTime.MinValue (year 0001), the database MinValue (1753) and a UI control DateTimePicker (i think it was 1970). So there were at least 3 different MinValues that were leading to strange behavior and unexpected results. (And I believe that there was even a fourth (!) version, I just do not recall where it came from.).

Use a nullable database field and change your value into a Nullable instead. Where there is no valid value in your code, there should not be a value in the database as well. :-)
