Description:
ParseMySql method in MySqlDateTime only sets IsZero property to true and never sets is to false (which is default).
When for example a DATE field is fetched from the table and a zero date is found '0000-00-00' all subsequent records in this field are indicated as IsZero(=true). That causes problems itself and for example in ToString() method which then returns '0000-00-00' even when Value is correctly filled in the instance (method explicitly checks IsZero and if set than returns zero date).

How to repeat:
See description.

Suggested fix:
insert explicit set: `isZero = false;` at the beggining of the ParseMySql() in class MySqlDateTime (file:MySqlDateTime.cs, line: 169). Method beginning then should look like this:
	internal void ParseMySql( string s, bool is41 ) 
	{
		isZero = false; // inserted statement
		switch (mySqlDbType) 
		{
// code then goes on unchanged...
