All Implemented Interfaces:

Serializable, Cloneable, Comparable<Date>

public class Date
extends Date

Date with database semantics.

Differs from java.sql.Date when serialized/deserialized in different timezones. Databases don't provide a time and therefore no timezone for a date, i.e. when sent over wire to different locations a date should always remain the same for all timezones. In java.sql.Data, however, the epochal time is serialized which may lead to a different date when deserialized in another timezone. In Date the effective date is serialized as YYYYMMDD to provide the same semantics as databases do.

Date

public Date(long date)

If the given milliseconds value contains time information, the driver will set the time components to the time in the default time zone (the time zone of the Java virtual machine running the application) that corresponds to zero GMT.

Parameters:

date - milliseconds since January 1, 1970, 00:00:00 GMT not to exceed the milliseconds representation for the year 8099. A negative number indicates the number of milliseconds before January 1, 1970, 00:00:00 GMT.
