| DateTime | | public class DateTime (Code) | | High performance converters from date/time byte encodings to JDBC Date, Time and Timestamp objects.
Using this class for direct date/time conversions from bytes offers superior performance over the alternative method
of first constructing a Java String from the encoded bytes, and then using
java.sql.Date.valueOfjava.sql.Date.valueOf() ,
java.sql.Time.valueOf java.sql.Time.valueOf() or
java.sql.Timestamp.valueOfjava.sql.Timestamp.valueOf() .
