DateTime t1 = new DateTime();

DateTime? t2 = t1;

t1 = t2.Value
//or
t1 = (DateTime)t2

System.DateTime? means that it is either a System.DateTime OR a null.  
System.DateTime means it can ONLY be a System.DateTime.

In other words they are they same apart from one being able to have a value null.
