If we have a BO that has a datetime column that we may at times want to use the date picker against in Strataframe what is the best method of setting the default in the BO Mapper and what is the difference between each method? IE... advantages, etc: FYI I mainly have used the first method which seems to work for SQL and Oracle.

First Setting: NULL VALUE OPTION = Return Alternate on Null / Set Null on Alternate (Value Type) and the NULL REPLACEMENT VALUE = new DateTime(1800, 1, 1)

Second setting:  NULL VALUE OPTION = Return Alernate on Null and the NULL REPLACEMENT VALUE = Convert.ToDateTime("1800-01-01 00:00:00.000")
