public class Date extends Date
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.

This method always throws an UnsupportedOperationException and should not be used because SQL Date values do not have a time component. |
