A thin wrapper around the java.util.Date class that allows the JDBC
API to identify this as an SQL TIME value. The Time
class adds formatting and
parsing operations to support the JDBC escape syntax for time
values.

The date components should be set to the "zero epoch"
value of January 1, 1970 and should not be accessed.

Since:1.1
