A thin wrapper around a millisecond value that allows
JDBC to identify this as an SQL DATE value. A
milliseconds value represents the number of milliseconds that
have passed since January 1, 1970 00:00:00.000 GMT.
To conform with the definition of SQL DATE, the
millisecond values wrapped by a java.sql.Date instance
must be 'normalized' by setting the
hours, minutes, seconds, and milliseconds to zero in the particular
time zone with which the instance is associated.
