Fabio Maulo commented on NH-2661:
---------------------------------

Neal, you can't change the TimeType that way because not all RDBMS may accepts a TimeSpan in the value of a parameter of DbType.Time.

In practice what you are looking for is something that use a DateTime in the domain and a TimeSpan for the DB.

> In .NET 4, setting a SqlParameter's DbType to Time does not work; it will be set to DateTime instead.  (http://msdn.microsoft.com/en-us/library/system.data.dbtype%28v=VS.100%29.aspx , c.f. http://msdn.microsoft.com/en-us/library/system.data.dbtype%28v=VS.90%29.aspx ).  To set a SqlParameter's DbType to Time, you actually have to set the SqlDbType property to SqlDbType.Time.  
> Unfortunately, this renders NHibernate unable to access TIME columns in the database if being used in .NET 4.0.
