According to http://edocs.bea.com/wle/wle42/drivers/mssql.htm#1025291 :

================================================== ====================
The java.sql.TimeStamp class in the Java 2 software is limited to dates
after 1970. Earlier dates raise an exception. However, if you retrieve
dates using the getString method, the jdbcKona/MSSQLServer4 driver uses
its own date class to overcome the limitation.
================================================== ====================

But I don't see API do***ent mentioned this limitation, anyone know more
about this limitation?
